Life hack: spacer (stretch) of Priora front struts


Lada Priora is a domestic car, the production of which started in 2007. It begins its history with the sedan model. Quite quickly, this model aroused the trust of buyers and gained great popularity. The Priora car, in addition to the sedan model, also has a hatchback and a station wagon.

Owners of any car want to improve its performance by constantly supplementing, equipping and tuning their “iron horse”. Likewise, Priora owners try to improve their car with each repair, adding more and more necessary car parts to it.

Front top and bottom

The upper and lower parts are reinforced at the front. The most popular amplifier is the upper extension of the cups of the front shock absorber elements on the Lada Priora. Firstly, they are easy to install, and secondly, they are clearly visible under the hood; their presence, in the opinion of many, gives the car a sporty look. Such designs are indeed widely used in professional motorsport. But a brace alone doesn't make a car a race car.

The part is attached to the front suspension strut cups from above, which creates a rigid connection between the right and left parts of the body. The cost of these parts is 700-1600 rubles. The original Lada Sport spare part is designated by number 21100-8403770-87. Price about 900 rub.

In the manufacturers' catalog there are amplifiers designated as two- or three-point amplifiers, but they are called four- or six-point amplifiers. They differ in the number of mounting holes:

  1. For two-point ones - 2 on each side, 4 in total.
  2. Three-pointers have 3 each, for a total of 6.

Expensive models are available with six mounting holes on each side:

  • Adjustable - the length can be changed, providing ease of installation on an old car with broken body geometry.
  • Non-adjustable - simpler in design, more rigid, but suitable only for machines with the correct distance between glasses.
  • A special type of strut is a stretching of the front struts for a Priora car, with an additional support attached to the engine (for a Priora with a 16 valve engine). The part allows you to increase the rigidity of the body and the mounting of the power unit. It has a complicated design and a price of 1600–2200 rubles.

The lower brace strengthens the suspension arms. The price of the lower part is 500–1200 rubles. The number of the lower reinforcing element of Lada Sport is 21100-5301265-87. Costs approximately 750 rubles. Many car enthusiasts note that installing a lower brace creates a more noticeable effect than adding reinforcement to the cups.

When replacement is required

It will not be difficult for a more or less experienced driver to understand that the silent blocks are out of order and they need to be replaced. First of all, you will feel a certain discomfort while driving, you will hear the impact of iron in the suspension. But that's not all.

Determining the need to replace silent blocks is not difficult if you pay attention to the characteristic signs of their wear:

  • While driving, strong or minor rubber squeaks are observed. It all depends on the degree of wear. Loud noise is a very bad sign;
  • A noise similar to a knock is heard in the wheel area. This indicates that the silent blocks are poorly fixed and they are gradually destroyed;
  • Cracks form on the surface of the elements, after which the process of disintegration of the silent block begins. In such a situation, it will be impossible not to hear a knock.

Ass around the perimeter and only between the glasses

To strengthen the rear of the machine, three types of struts are used:

  1. Single strut brace attached to the top of the rear shock absorber cups.
  2. A rectangular “TV” located around the perimeter of the opening between the elements.
  3. A set forming a cross-shaped structure.

These amplifiers are either unregulated or adjustable. The original rear strut strut is designated by number 21100-5601265-87. Price – 1000–1100 rubles. The lower one, from Priora, costs about the same, similar to other manufacturers.

Its installation makes it impossible to transport large items inside the cabin; when sporting a car, its cargo characteristics do not matter.

The rectangular rear strut brace includes four components:

  • 2 horizontal (top, bottom).
  • 2 vertical.

The parts are connected to each other at their ends, forming a rectangular structure. The upper horizontal pipe is attached to the top of the rack glasses. Bottom - to the transverse floor panel. On some models of “TVs,” quick-release upper horizontal elements are installed between the rear pillars; this helps maintain a large volume of luggage compartment when the rear seats are folded. Cost – 3700-4500 rubles.

The rear cross-shaped amplifier is present in the Lada Sport range. Article – 21100-5601260-87. Price – from 3000 rubles. Stretches of similar design are produced by many companies.

“Fucking basin. "

Hi all! My name is Mikhail, now I’ll tell you a story about how I managed to exchange my two-wheeler for a 2010 Camry. It all started with the fact that I began to be wildly irritated by the breakdowns of the two-wheeler, it seemed like nothing serious was broken, but damn it, there were so many little things that really started to irritate me. This is where the idea arose that it was time to change the car to a foreign car. The choice fell on the melting Camry of the tenth years.

Yes, I had matured morally, but financially I just couldn’t handle it. I’ll say right away that I am against loans and taking a car, especially not a new one, on credit is unreasonable. My salary is 24k a month, so collecting 600-700 thousand is almost impossible for me. I started looking for different ways to make money on the Internet. You can’t imagine how many scams there are, what I haven’t tried: sports betting, network marketing, and even the volcano casino, where I successfully lost about 10 thousand ((The only direction in which it seemed to me that I could make money was currency trading on the stock exchange, they call it Forex. But when I started delving into it, I realized that it was very difficult for me. I continued to dig further and came across binary options. The essence is the same as in Forex, but it’s much easier to understand. I started reading forums, studying trading strategies. I tried it on a demo account, then opened a real account. To be honest, I didn’t manage to start earning money right away, until I understood all the mechanics of options, I lost about 3,000 rubles, but as it turned out, it was a precious experience. Now I earn 5-7 thousand rubles a day. I managed to get the car buy after half a year, but in my opinion this is a good result, and it’s not about the car, my life has changed, I naturally quit my job, I have more free time for myself and my family. You’ll laugh, but I work directly on the phone)) If If you want to change your life like me, then here’s what I advise you to do right now: 1. Register on the site 2. Practice on a Demo account (it’s free). 3. As soon as you get something on the Demo account, top up your REAL ACCOUNT and go to REAL MONEY! I also advise you to download the application to your phone, it’s much more convenient to work from your phone. Download here.

Removal and installation of all types of spacers

Almost all amplifiers of AvtoVAZ cars are installed in standard places and do not require drilling, welding, or other changes to body parts. A standard set of wrenches is sufficient. Sometimes it is necessary to use other fasteners. For example, when installing the lower part, longer than standard bolts are used.

Most manufacturers include with their products the necessary components and installation instructions, which include the following steps:

  • Removing standard fasteners.
  • Installation in place of a new part.
  • Fixing the structure using removed or special fasteners.

Adjustable amplifiers require pre-adjustment of the length in accordance with the actual dimensions of the car body by rotating the bushing. It is impossible to change the length of the reinforcing elements in order to influence the geometry after their installation.

What is the process of installing a stretcher?

The installation, in fact, is not very complicated; it can be done on your own, without calling for service. You need to use a size 1 wrench to unscrew the nuts on the “cups” without fear that they will fall through. Install the spacer and tighten the nuts. If you purchased an adjustable spreader bar, the distance between the support plates is adjusted before installation and fixation. Otherwise, the wheel alignment angles may be disrupted.

Pros and cons of stretching the front struts

Strengthening the car's body, both front and rear, makes it stiffer. For example, the upper part of the struts reduces the movement of the suspension mounts, reduces stress at the mounting points, and increases rigidity. Thereby:

  • The car becomes more composed when cornering.
  • The maneuverability of the vehicle increases due to increased control accuracy.
  • Improves stability during straight-line movement.
  • Body deformation is reduced when driving on uneven roads.
  • The likelihood of fatigue cracks in metal elements is reduced.
  • The main disadvantage of installing reinforcement is that due to the rigid connection between the right and left parts of the car, elements on both sides are damaged in an accident.

In addition, boosters violate the vehicle's manufacturer-designed crumple zones, which impairs safety in serious accidents. Therefore, using the part for civilian use is inappropriate in most cases.

The purpose of the front, lower, rear, and other reinforcements is to increase body rigidity. This improves the driving characteristics valued in motorsports, but reduces the safety and practicality required for normal use of the car.

Adjustable stretchers on Priora - what are they for?

Over time, the distance between the car's suspension cups changes slightly (on average from three to eight millimeters), so installing the brace is problematic - you have to use a jack, lift the front wheels and arm yourself with a pry bar. Accordingly, adjustable stretching was invented to neutralize this effect. It is not possible to adjust the stretcher that is already installed on the machine.

Description

Lower lever spacer (stretch) AR 0160 / AR10-2801070.

Purpose: reduces the movement of the front suspension arm bracket by more than 3 times. Reduces stresses occurring in the lever bracket and the spar-to-floor connector by 35% and stresses occurring on the front panel in the area of ​​the right steering gear bracket by 8.5%.

The kit includes: — Lower spacer — 1 pc. — Bolt M12x1.25x80 — 2 pcs.

The procedure for installing the lower spacer.

1. Remove the mudguard.

2. Unscrew the nuts and remove the bolts securing the arms to the body.

3. Attach the spacer to the arm mounting brackets, and, aligning the holes on the body with the holes in the spacer, insert the M12 bolts from the kit.

4. Fit and tighten the nuts.

5. Reinstall the mudguard by tightening the nuts on the front. At the rear, screw the mudguard to the spacer with two M8 bolts through the existing 10mm diameter holes. in the splash guard.

The manufacturer reserves the right to change the characteristics of the product, its appearance and completeness without prior notice to the seller.

What does the Priora front suspension diagram look like?

The structure of the part is shown in detail in the figure, where the following components are indicated in the kit:

  • rounded fist;
  • eccentric type bolt;
  • strut responsible for shock absorption;
  • lever arm;
  • a rod suitable for the stabilizer;
  • a bracket fixing a cushion related to the stabilizer bar;
  • a stand that fits the stabilizer bar;
  • transverse suspension component;
  • ball type support;
  • stretching;
  • spring device;
  • rod nut;
  • a detail limiting the rebound stroke of the support located in the upper part;
  • support placed at the top;
  • bearing;
  • silent blocks;
  • a gasket created specifically for a spring device;
  • spring cup at the top;
  • an element limiting the compression movements of the upper support;
  • compression motion buffer;
  • case for protection.

How to understand that the racks have become unusable

On a Priora, it is quite easy to determine that the struts have become unusable; you can go to a service station where they will check the chassis using a mount or drive the car onto a vibration stand.

You can determine the malfunction of the racks yourself. If the car struts are faulty, it will experience the following problems:

  • The car will sway after each smooth bump. You can check this by rocking the car yourself and letting go; working struts should stop the car from rocking, but faulty ones won’t be able to do this and the car will continue to rock.
  • Another point of faulty struts will be knocking noises when driving over uneven surfaces similar to washboard gravel, asphalt joints, etc.
  • You should also inspect the racks for leaks. If there are traces of leaking liquid on the racks, then the rack is faulty and must be replaced.
