Gas-oil struts for the front suspension KYB Excel-G (Kayaba) for Lada Kalina, Kalina 2, Granta | buy spare parts at low prices with delivery throughout Russia

Lada Granta shock absorber struts are designed to dampen vibrations and absorb shocks and shocks acting on the car body. When the service life of the racks comes to an end, they should be replaced with new ones (only in pairs), but do you know which racks to put on the Grant?

When to change Lada Granta struts ?
The service life of the shock absorber strut depends on the operating conditions of the vehicle. Struts whose service life has come to an end are determined during diagnostics using a special stand, or in a simple, popular way, when they notice that the car has begun to hold the road poorly and is no longer as stable as before. You can also rock the corner of the car; if there is free swing more than 1-1.5 times, then the strut needs to be replaced. The approximate service life of shock absorbers is 60-100 thousand km. mileage Which Grant stands are better? There is no consensus; each type of rack has its own advantages and disadvantages. For example, oil shock absorbers are soft despite their low price, which makes the ride more comfortable. However, the small operating temperature range makes them tough in winter. Gas or gas-oil shock absorbers, as a rule, have a higher cost, but are considered more technologically advanced; the car becomes more stable.

What racks are on the Grant from the factory ? AvtoVAZ installs SAAZ oil shock absorbers. Catalog numbers:

It is believed that imported struts are of higher quality and more reliable, so many people choose Kayaba or SS-20 shock absorbers.

What is the approximate price of racks for Grant ? Front — 2100 rub., rear — 1200 rub. It is worth considering that depending on the region, the cost of racks can vary greatly.

Have you decided to replace the racks? Be sure to check the condition of the remaining suspension elements; the trip will be comfortable and safe only if all components are in good working order.

When choosing shock absorbers for the Lada Granta (VAZ 2190), you should know that the front struts of this car will differ depending on the engine power (although all with a 1.6 liter engine) and body type, and the numbers are different on the right and left sides. While everything is much simpler with the rear shock absorbers, all modifications use the same ones. To make it easier for you to find the required shock absorber, use the tables of original numbers and their analogues.

Which racks to choose for the Lada Granta - install normal spare parts

Selecting quality parts for car maintenance and repair is an important task for every motorist. In order for the car restoration to be high-quality and durable, it is better to use the most interesting options for parts with a sufficiently high quality. It is worth remembering that the reliability of spare parts determines their service life, as well as the quality of operation. Unfortunately, the cost of parts also greatly depends on this factor. Today we will talk about the racks that are best used on the Lada Grant. Considering the fact that factory suspension elements fail after a maximum of 50,000 kilometers, you have to look for something more interesting and non-standard. You can buy factory solutions again only under warranty, when you will receive a free replacement and will not charge money directly for the racks.

Today you can buy a shock absorber liner from any manufacturer, including some of the most amazing brands from around the world. In this case, it is not necessary to change the rack assembly; you can make a constructor by installing an insert of a specific selected type. This will completely change the behavior of the car. The stock shock absorbers on the Grant are simply amazing - they behave exactly as the Lada 2110 did back in 1998. There have been no significant changes in the suspension. At least regarding the struts and operating comfort of the car. There are different brands and specific recommendations for the types of racks. Let's take a closer look at each aspect of purchasing new suspension parts. This will help you better service your car and obtain the necessary features for operating a vehicle.

Which racks are best to put on a Kalina station wagon?

Which front struts are best to install on a Kalina 1118 station wagon?
How many drivers have so many opinions about which struts are the best of the best? Everyone takes into account their financial capabilities and driving style. So, which front struts are best to install on a Kalina 1118 station wagon? In order to determine which ones exist and what they are best suited for, it is necessary to identify the existing types. For cars, they use oil, or, as they are also called, two-pipe, and gas, or single-pipe.

The first include two tubes that are located one inside the other. One tube plays the role of a housing and contains hydraulic oil inside, and the other has a piston inside where vibrations are damped. Such shock absorbers are famous for their low price, simple design and long service life, but they have their own nuances, such as short response time and insufficient damping force.

Gas parts include the following parts: working cylinder, expansion tank, piston and its rod. This type is already more expensive, but is designed for heavier loads. From this we can conclude that oil ones are suitable for those who prefer a quiet ride and comfort, and gas ones for lovers of speed and dynamics. Therefore, each driver must answer the question of which racks are best to install on a viburnum for himself.

Oil or gas-oil - the first question that needs to be resolved

If you take inexpensive racks that are made in Russia or China, then there are virtually no differences between oil and gas-oil. But when you buy products from a great brand, you can notice a very noticeable difference. In particular, gas-oil will be a very tough sports solution. Oil shock absorbers offer customers a number of specific advantages that will be important in the operation of vehicles:

quite high ride comfort, which can be called significant progress for the Lada Granta, overcoming most potholes without noticeable effects in the car interior;
low level of penetration, that is, you will not catch unpleasant sounds when the rack shows its long free stroke, there is no risk of breakage;
the rod stroke is quite long, it is possible to hang the wheels almost like an SUV, this helps on large bumps and dirt roads;
your Lada Granta will not only become softer, but will also be able to transmit information about the road more energy-intensively, there is no intrusive data, only the necessary details;
The cost of oil shock absorbers is often slightly lower than gas-oil shock absorbers, which is why the vast majority of domestic car owners buy them.

Of course, it all depends on the brand. You can buy an excellent Japanese version of the insert and get simply wonderful operating possibilities. There is the option of purchasing a cheap Chinese rack and being completely disappointed in its use. But for now, let's limit ourselves to making a decision on the type of shock absorber. It can be a soft oil or a sports gas-oil type.

How to determine if shock absorbers are faulty

Often, traces of oil appear and disappear over time, and then, when the driver notices a loss of controllability, the strut becomes dry again. To determine its serviceability, you need to grab the roof of the car and try to swing it strongly.

Serviceable shock absorbers should stop the body already on the second swing. If the car continues to rock, the struts need to be replaced.

The problem must be diagnosed at the first sign. There are several symptoms that indicate a damaged shock absorber:

Knock when driving or extraneous sounds in the suspension. This problem occurs extremely rarely. As a rule, this implies destruction inside the strut housing and the rod simply begins to hit the housing, making unpleasant knocking noises. This sound will appear when driving over both large and small irregularities and will haunt the car owner no matter how much the car rocks.
Deterioration in controllability. The most dangerous and obvious sign of shock absorber failure. As you know, struts are needed to dampen body vibrations that occur when suspension springs operate. If these vibrations are not suppressed, the car begins to sway strongly at high speed and the wheels may briefly lose traction with the road surface. It is worth noting that this malfunction is quite dangerous.
Leaks on the rack body. Deterioration in controllability occurs due to internal damage to the shock absorber and its depressurization. Traces of leaking oil, which is the main shock-absorbing component of this part, may appear on the rack.

If, after all, the reason for the knocking on Kalina is in the shock absorbers, then you should select the right new spare parts. Don’t even try to restore them; doing so is impractical, labor-intensive and expensive.

Manufacturer is one of the most difficult questions for the buyer

Buying unusual, expensive shock absorbers is becoming a necessity today. In conditions of very tough competition and the global crisis in the automotive market, cheap companies are starting to produce worse and worse spare parts. Therefore, the products of some corporations have long ceased to be reliable and of high quality. It is worth highlighting the following brands as an ideal solution for Lada Granta when purchasing racks:

KYB - you can combine separate liners with a stock strut and you will get an almost full-fledged Kayaba, the shock absorbers are very durable and high quality;
Acomi is a fairly affordable brand, but much better than Chinese solutions, a completely acceptable solution if you choose an expensive series like Comfort PRO;
SS20 - the company makes special racks for the Granta, so they fit perfectly, quite adequate quality, but there are many fakes and a number of shortcomings in movement;
Demfi - not so durable, but quite affordable racks, which are also ideal for the Lada Granta, quite high-quality performance, but you need a choice;
Plaza is one of the cheapest options of more or less decent quality, but only some kits from the manufacturer are pleased with their reliability and durability.

So there are not many chances to choose from brands. Of course, you can try Monroe struts or buy some racing solutions from France and Germany. But this will be too expensive. The same as Kayaba, but this solution is classic, and is simply perfect for the Lada Granta. If you have enough money for a Japanese manufacturer, buy their offers for your car.

Springs and strut supports for Lada Granta - choose the best

It is better to install original springs. No manufacturer offers the same accuracy as VAZ in this case. There is only one reason for this - no one wants a manufacturer of springs specifically for Grants to do it efficiently and cheaply. Therefore, you have to give preference to stock solutions. As for the upper and ball joints of the Lada Granta struts, it is worth paying attention to the following features:

the upper supports of the front struts are most often installed in Russian SS20, there are options for using more expensive solutions, but this purchase takes a long time;
but the rear upper supports for shock absorbers are not easy to find, the Acomi company will help you here, but it is better to contact the officials and buy what was originally in your car;
VAZ ball joints are no good and cost 20-30 thousand, so it’s better to buy Belmag or Forward, which are made in Russia and cost very affordable money;
you can also choose German Kraft ball joints, but here you should beware of fakes, so always choose parts based on price and quality with a specialist;
It is better to buy any small details such as fasteners, bolts, nuts and washers from the factory, as otherwise you may simply not reassemble the car properly after disassembly.

There is an opinion that factory spare parts are always better than analog ones. But in the case of the Lada Granta this is not at all the case. Sometimes you can find quite adequate spare parts that fit Granta from German and Japanese brands. And then you can buy really wonderful additions and parts that last for years. However, any part has its own service life, and this also needs to be remembered.

When is it necessary to replace shock absorbers?

Which front struts are better to install on a Kalina 1118 station wagon? The fact that it’s time to replace the shock absorbers is indicated by their wear, which is manifested by oil leakage, because due to the lubricant, which reaches high temperatures, the rubber parts of the car suffer;
rocking of the car when driving and noise during operation - a characteristic knock appears, which can also be due to incorrectly installed racks. If the efficiency of shock absorbers is lower than 20%, then this indicates the need for replacement, but numbers in the form of 40% are a good sign. The service life depends on many factors, the main of which are weather conditions and roads, as well as the driver’s driving style. With the help of diagnostics from a specialist at the required stand in the workshop, or at home, you can identify racks that have already become obsolete.

It’s worth taking a closer look, but if you start to notice that your car is quite unstable and doesn’t hold the road well, then this is already a wake-up call. There is another way, try to swing the corner of the car, and look at the result, if the free swing indicator is more than 1-1.5 times, then your rack really needs to be replaced. Often, racks operate stably from 60,000 to 100,000 thousand km. mileage

Replacing Lada Granta struts and supports - several important features

If the rear suspension is more or less clear, then the front suspension always hides more mysteries. It is the front struts and supports that most often fail. Unless you constantly pull a trailer or tow careless friends. The load on the front of the car is always increased, so you often have to work with the front suspension parts. Changing the front struts on a Grant is not so easy:

first you need to completely remove the rack and disassemble the lower parts of the chassis for subsequent installation on a new mechanism for damping road irregularities;
if the rack is installed as a new assembly, then there will be much fewer problems, you just need to install a new one in place of the old mechanism and reassemble it in the reverse order;
if only the liner is changed, it is worth completely disassembling the strut, removing the spring and taking out the shock absorber, checking the degree of wear of all parts and the need to replace them;
Next, you should replace the strut liner, carry out technical checks right at the assembly site and reassemble the shock absorber to its original position;
Next will be the installation of the rack in place, assembly and rough diagnostics of all the components that you repaired, this will give complete confidence in the quality of the work.

Let's sum it up

There are a number of features of operating the Lada Granta on Russian roads. For some reason, a domestic car is not very suitable for our roads; it crashes and fails instantly. Sometimes you come across a well-built car that doesn’t show any character after 100,000 kilometers. But in most cases, the Garnet justifies the title of the cheapest car in the Lada line. And when it comes to racks, the manufacturer saves a lot on these elements. The installation of low-quality suspension elements leads to the fact that more and more people, after purchasing Grants, repair it under warranty.

However, sometimes it is better to cancel the warranty and install normal racks, supports and other parts. In this case, you will ensure the normal service of your car’s suspension and will be able to establish normal operation of each unit. This will take a certain budget, but can provide you with comfortable movement without any particular difficulties or problems. Of course, even the best quality rack will eventually fail. But it can travel far beyond 100 thousand kilometers. What brands of spare parts do you choose to repair the suspension of your Lada Granta?

Front shock absorbers for Granta

All Granta cars are equipped with stock oil shock absorbers produced at the SAAZ plant (Skopinsky Automotive Aggregate Plant). The original number of the front shock absorber struts for Granta can have three options, since cars come in different years of production, and are installed depending on the modification of the body and engine power. This information is displayed in the table.

It should be mentioned that for fans of an aggressive driving style on LADA Granta Sport and LADA Kalina Sport 2, gas-filled (gas-oil) shock absorbers of the “Sport” series with a shortened rod stroke were produced from the factory (art. A190291500440).

The main technical dimensions of the front shock absorbers for the Lada Granta are shown in the table:

The same shock-absorbing front struts as on Granta are installed on LADA Kalina 2 (VAZ 2194, 2192).

Analogs of front shock absorbers VAZ 2190 and 2191

Many car owners prefer foreign analogues, which are superior in quality and more attractive in price. But even here, not everything is so simple - when going to the car market, you should beware of Chinese counterfeits, both domestic and foreign spare parts.

Choosing shock absorbers for Kalina

Sports pair of shock absorbers

Today, three types of struts are installed on the Lada Kalina car.

SAAZ racks are an option proposed by the plant. The advantage is the inexpensive price and easy installation. But there are more disadvantages: poor handling and poor car dynamics on difficult roads.
Kayaba struts are a part produced using Japanese technology. It has the best quality and durability. By installing “Kayaba”, you will immediately see a positive result: the car will move quieter and softer. But there is one catch: today these racks are produced under license by Chinese companies, but their quality is strikingly different from Japanese ones. It's hard not to get into trouble.
“Acomi” struts are manufactured by a domestic company and are offered for both GAZ cars and VAZ models, including those installed on Kalina. Everything is good here, but you need to take into account that a one-year warranty is given only if the car owner repairs the car at the service stations specified in the contract.

You can buy SS20 racks. The part holds the road perfectly and eliminates noise, knocks and impacts. Movement becomes comfortable, safe, easy.

Before purchasing and installing shock absorber struts in the Lada Kalina suspension, the owner should decide on the question - what type of these products would he like to see in his car? Which stands are better? There are two options for struts that are suitable for a Russian small car: oil and gas-oil, but which shock absorbers are better?

Rear shock absorbers on Lada Granta

The manufacturer of all original rear struts is the same as the front struts. Therefore, they are also similar in characteristics. When selecting a shock absorber for the rear strut of a Lada Granta, you should take into account that they are symmetrical and fit both left and right, and do not differ from what engine modification is installed on the car.

Below is all the information in tabular form about the main parameters of shock absorbers:

Analogs of rear shock absorbers on VAZ 2190 and 2191

The original rear ones are also slightly more expensive than the average price of replacements. Because of this, analogues are also in high demand. The best option would be to purchase rear shock absorber struts in packaging specifically from the manufacturer SAAZ (red box), and not the standard VAZ one (blue), which is true, analogues offer substitutes with slightly better rigidity characteristics and service life.

Which shock absorbers for Lada Granta should I choose? Many foreign analogues for the Lada Granta - VAZ 2190/2191 are superior to standard racks in a number of indicators, such as: rigidity, noise level, anti-corrosion coating, and the presence of reinforced mounting of silent blocks. But not all stands have such characteristics, especially if we are talking about a Chinese counterfeit.

The most popular manufacturer of racks among grant providers is SS20. The company specializes in producing racks specifically for Lada cars, including Grants. Therefore, there are no problems with installation, plus their price and quality are more acceptable, except in those rare cases when there are design flaws.

Of course, you can try to purchase Monroe or other spare parts made in Germany or France. But this will be too expensive an option.

Front struts for Kalina: which ones are better to choose

Let's start with the fact that Kalina's rear shock absorbers often take more care than the front ones. For this reason, it is Kalina front struts or Kalina 2 struts that are more in demand on the market. That being said, there are several solutions available that can be used for replacement. As a result, drivers often find it difficult to answer which struts to take, oil or gas, as well as which manufacturer, etc.

Let us immediately note that at the Kalina factory it is equipped with SAAZ oil struts. The advantages include softness and affordable cost. At the same time, the handling is not the best, and the struts do not have a long service life and knock in winter until the oil warms up in the shock absorber. To improve handling and gain greater reliability, you can replace the standard shock absorbers with Kayaba ones. Moreover, if you need a Kalina strut, many people prefer Japanese Kayaba shock absorbers (KYB).

However, not everything is as smooth as it may seem. On the one hand, the Kalina rear strut or the front struts for the Kalina of this company are distinguished by good characteristics and performance. Handling and stability are noticeably improved, the car holds the road better, rolls less when cornering, the struts themselves last longer, etc.

In fact, especially when it comes to front shock absorbers, drivers note that the Kalina front struts from KYB are not the cheapest, and are very hard, can be noisy, etc.

Please note that such operation of the strut is a price to pay for stability, since the shock absorbers are gas (gas-filled). Compared to standard “oil”, hardness increases noticeably.

We also note that some of the negative reviews are the result of the fact that, given the popularity of the brand, there are a huge number of fakes on the market. When choosing, you need to purchase products only from authorized dealers

Also, when installing racks on a car, it is important to follow all the rules, properly bleed the racks, etc.

If Kayaba is not suitable for one reason or another, you can choose ASOMI or SS racks. These are domestic manufacturers specializing in the production of parts for VAZ, GAZ.

Of course, the quality of the racks is inferior to the original Kayaba, but they often perform better than the stock ones. Moreover, in practice, for Kalina, the SS line is often considered the best solution (for example, SS-20 for Lada Kalina). If this Kalina front strut is considered, the price will definitely be more favorable than the Japanese counterpart.

On these racks, when properly selected, the car becomes medium in rigidity, while comfort is maintained and handling does not suffer much. Another plus is a two-year warranty versus 1 year for ASOMI.

In the SS line, there are struts for Kalina: Highway 1118, Standard 1118. Standard 1119, Sport 1119. You can also purchase the entire set of front and rear suspension “Kalina Sport”, etc. This is convenient, since the presence of other parts besides the struts allows, if necessary, to immediately replace springs, etc.

Note that the “Standard” struts are similar to the factory ones, however, the “Highway” and “Sport” versions differ from both the stock and the “Standard” line. For example, “Sport” is softer than Kayaba when driving on bad roads, but holds the car very well on the highway.

As you can see, the issue of selecting shock absorbers is not as straightforward as it might seem at first glance. In the case of Lada Kalina, well-known imported KYB shock absorbers are not always the optimal solution.

For example, some owners of this car often practice a scheme where the Kalina rear strut remains standard, and SS-20 are installed in front. This allows for improved handling without sacrificing comfort. One way or another, the information above allows you to choose the best option, taking into account individual preferences, goals and objectives.

When to change Lada Granta struts?

The service life of the shock absorber strut depends on the operating conditions of the vehicle, road conditions, and driving style. To find out the remaining service life of a rack that is coming to an end, you need to use diagnostics using a special stand.

There is a simpler way: if the car begins to hold the road poorly and is no longer as stable as before, there is a knocking or drip on the racks - it’s time for a replacement. The approximate service life of stock shock absorbers is 60-100 thousand km. mileage

Oil or gas. What to choose?

Hydraulic shock absorbers used in cars can be divided into two groups: oil and gas. They work on a similar principle. However, they differ from each other in their damping medium and, therefore, in their properties:

The oil shock absorber is a twin-tube shock absorber. As the name suggests, it is equipped with two pipes: the outer one serves as the housing, and the inner one has a piston and hydraulic fluid that reduces vibrations. When the piston moves, oil flows between the pipes thanks to special valves. During compression, which is the first stage of shock absorber operation, the piston rod forces oil to flow down the piston. This is possible thanks to a one-way valve. This reduces the amount of space in the cylinder for the damping medium, i.e. oil. Its excess enters the compensation tank through the bottom valve. During this flow, resistances arise that weaken the vibrations. The piston rod then protrudes from the cylinder, which increases the pressure of the damping fluid on the piston. Oil flows through the valves again. During this process, vibration damping is resisted again. The volume of the piston rod is equalized by the oil flow in the compensation tank.
Gas shock absorber is the general name for oil and gas shock absorber. Unlike its predecessor, it consists of a single tube that contains a piston. The lower part of the shock absorber contains compressed gas (nitrogen), which is separated from the damping agent (oil) by a movable partition. Thanks to this design, the damping system does not require a compensation tank. The first stage of shock absorber operation is compression, during which the pressure increases. Under its influence, the piston rod slides into the working chamber and forces the piston to move down. As a result, oil enters the space above the piston. This is followed by reflection, during which we observe the upward movement of the piston. Thus, the oil pressure above the piston increases and the fluid moves again.

Shock absorbers are often considered only as elements that should provide better ride comfort. Meanwhile, they are also of great importance for the safety of car travel. They affect the vehicle's grip on the ground. When choosing these parts, it is worth considering whether gas or oil shock absorbers will work best.

Returning to the question of which racks are best to install on a grant sedan, we recommend using oil ones; they will make the car ride softer and more comfortable. While gas ones are a more sporty solution.
