The towbar on Largus is considered an indispensable element, which applies not only to the cars of summer residents or owners of country houses. Sometimes it is able to solve many problems associated with the transportation of large cargo. At the same time, the towbar allows you to safely move over rough terrain, without fear of getting stuck off-road.
No matter what anyone says, a towbar is a multifunctional towbar
Basic functions of the hitch
Most car owners mistakenly believe that the Lada Largus towbar is mounted exclusively from the position of protection against rear impacts during road accidents. In many ways this is true, but why then is it allowed to drive with it all over the world only if there is a trailer. This is due to the fact that the car, on the contrary, is damaged much more if the impact falls on it rather than on the bumper. In this case, the advantages of a removable tow bar are obvious.
It is believed that such a tow hook is an elementary means of transportation in the event of a breakdown. However, it also provides a rigid connection to the trailer, providing it with maneuverability and allowing it to move along a vertical axis.
In addition, the tow bar sometimes connects the vehicle's electrical system to the trailer's lighting components. In this case, all maneuvers must be duplicated by optics located at the rear: stops, turns or other visual signals.
Design options
Let's start with choosing a trailer hitch and try to determine which one is better.
There is a wide selection of manufacturers and suppliers on the market. So the list of those in demand includes:
- Baltex;
- bosal;
- PT Group;
- Leader Plus, etc.
But you shouldn’t rely only on the brand, since a smart choice requires a comprehensive approach to the issue.
The various types of towbars available on the market are confusing to the buyer. Therefore, first of all, let’s understand this.
Main types
Varieties of towing devices can be structured according to different characteristics that affect the size of the tow bar on Largus. The following options are mainly used.
By mounting method:
- fixed (included in the basic package);
- removable (can be removed if necessary so as not to spoil the appearance of the vehicle);
- flanged (fixed with bolts to special platforms).
By construction method:
- ball type “A” (load not exceeding 150 kg);
- ball type “H” (load not exceeding 150 kg, but relatively cheaper than its predecessor);
- ball type “F” and “G” (transportation of loads up to 3.5 tons, with the ability to change the height of the structure fastening);
- “V” type ball (load capacity up to 2.5 tons, non-adjustable due to insufficient number of holes);
- ball type “VMA” (with a vertical mount that can be quickly removed).
If we talk about the above-mentioned domestic car, today it is very popular to install a tow bar on a Lada Largus with a ball of the latest type. It is very easily removed, becoming an inconspicuous mount that can be mounted if necessary.
Electrical wiring installation
First you need to remove the rear lights and run the trailer wiring through the standard holes. The wiring will be fixed to the towbar using plastic clamps. The main thing in this matter is to make the connection strictly according to the diagram.
The left connector has the following diagram:
- brake light (orange wire);
- mass (black insulation color);
- rear PTF (pink);
- left turn duplication (green);
- side lights (blue wire).
The wires on the right connector are slightly different. The purpose of the orange, black and blue wires is similar, and the yellow one is responsible for turning on the reverse indicator, the gray one is responsible for turning on the right turn signal repeater. Parking sensors are connected separately. All connections are carefully insulated. Work must be carried out with the negative terminal of the battery disconnected. Only after the wiring is correctly connected can we say that the trailer hitch is installed.
Arguments influencing the choice of tow bar
When choosing such a device for the Lada Largus, you should take into account such characteristics as the maximum vertical or horizontal load. To calculate it correctly, you need to know the approximate weight of frequently transported cargo and the trailer, the configuration and type of coupling element.
If the load on the towbar exceeds the maximum permissible level, then not only it can be damaged, but also a large part of the body of the car itself. Moreover, if this happens on the road, then such a breakdown can cause a traffic accident.
Nowadays, when there is a large selection of parts, it can be difficult to decide whether to give preference to cheapness or quality
Trailers for LADA cars with optimal characteristics
For the LADA model range, we offer trailers that are optimal in terms of total weight and are spacious enough to solve almost any transportation issues.
For example, the “SST-7132-MINI” model is perfect as a trailer for LADA Largus, the total weight of which is 500 kg with a load capacity of 400. This ratio gives you great opportunities with trailer dimensions of only 2.4 m in length and 1. 23 m in width, which will allow it to be used even on a narrow road.
You can always get advice on selecting a trailer for LADA Kalina, Granta, Largus or another model by phone. We select the length of the passenger trailer and other parameters based on the capabilities and specifications of your car, which allows you to avoid overpaying for unnecessary options or excess weight.
Towbar installation steps
Selection of tools
In order for the installation of the towbar on Largus to proceed correctly, it is necessary to prepare the necessary tools in advance. This procedure cannot be accomplished with just a Phillips screwdriver or an adjustable wrench.
Here you should pay attention to lifting devices: working under a car raised with a jack is very dangerous. Taking this into account, installation of the towbar is carried out only in the inspection pit. Of course, you can resort to using a stationary lift.
If you plan to drill holes, then a torque wrench will greatly simplify this task. In addition, most fasteners also need to be tightened with them.
You should first study in detail the instructions for the installed mechanism, where, as a rule, step-by-step installation of the towbar is prescribed. Particular emphasis is placed on ensuring an appropriate level of tightness.
Other tools you will need include clamps, drills, wrenches, bolts and nuts. If you intend to connect the Largus tow bar, or more precisely, the headlights and lights on the trailer, then you should prepare wire cutters, wires and electrical tape.
Preparatory work
Before direct installation, you need to make sure that you purchased exactly the device that is suitable for the Lada Largus. Reading the instructions and checking the installation location are some of the important actions that are primarily performed by the car owner.
It is strictly forbidden to start connecting a trailer if the coupling points are subject to corrosion or mechanical damage. In addition, the safety measures of the car owner himself - the use of special tools for their intended purpose and protective devices can protect him from injury.
Installation should not begin when the machine is tilted. After all, even a few degrees of deviation from the norm can have catastrophic consequences. The transmission should be in neutral, the front wheels locked, and the parking brake raised.
After the car has been installed in the inspection hole, it is firmly fixed with jacks. The terminal is removed from the battery, and the trunk is cleared of flammable parts. This will prevent the spread of fire in the event of an unexpected fire.
Fixing the towbar
When the Largus towbar drawings are used before attaching the towbar, this greatly simplifies the process of the same name. If the holes have been drilled in advance, the mechanism is simply attached using a pair of clamps. If they are missing, a drill will be useful, which will quickly make them in the bottom of the trunk.
The towbar is tightened using nuts and bolts with a diameter of 14 mm. In this case, the holes themselves must fully correspond to the fasteners.
In addition, two additional holes are made on the inside of the trunk using reinforcing linings, which help securely fix the device and remove part of the load from the body. Upon completion of installation, it is recommended to lubricate all attached parts with a special compound.
Wiring connection
First of all, you need to think about where it is best to place the wire connections and sockets. Here you need to purchase a good kit that will be universal for any vehicle, including the Lada Largus. This significantly reduces the likelihood of short circuits or other faults. In addition, the instructions for it describe in detail the entire connection diagram, and the car owner will only have to do it himself.
It is recommended to carry out the wiring connection with the trailer itself, since there are non-standard wiring diagrams on trailers

Digital control of electrical equipment assumes that thick conductors do not go directly to the light devices from the steering “dragonfly”, “frog”, relays and other switches to the tail lights, stops and other light devices. The supply voltage and digital control signals are received there.

A simple twist-type connection to the tail light conductors is inappropriate here. Even if you connect directly to the rear headlights, which are now mostly LED, it is not a fact that the electronics will not display an error message and turn off these lights altogether, since the current consumption will be exceeded.
