The manufacturer has provided the option of transporting goods using a trailer, but the towbar (towbar) is not included with the VAZ 2107 models sold. Installing additional equipment on the car should not cause damage to either the vehicle itself or the car owners’ wallet.

The ability to transport cargo using a trailer makes the VAZ 2107 a more versatile vehicle (if it does not have the most voluminous trunk). In the basic design, AvtoVAZ engineers provided only towing eyes. The presence of a tow bar will not only increase the load capacity, but also significantly improve the fastening of the tow rope, if necessary.

Type of towbars for VAZ 2107

The towbar is selected depending on the load capacity of the trailer used . For a VAZ 2107 car, it averages 350 kg. Trailers for passenger cars vary in purpose, design features, and, consequently, total weight. They can transport from 400 to 600 kg.

For installation on the VAZ 2107, the following manufacturers and models of towbars are recommended:

• Leader-Plus, VAZ-11H, maximum weight 600 kg;
• Avtos, VAZ-55, trailer weight up to 800 kg, VAZ-35 - up to 800 kg;
• Bosal, 1203-A, 1203-N – weight up to 600 kg;
• Trailer, 2105, 2105.R – weight up to 750 kg;

This model uses a type “A” tow ball. The maximum load on the ball varies depending on the final weight of the vehicle, trailer, and the tow ball itself.

Types of trailer hitch

• Removable.

Fairly easy to install. Due to their design capabilities they are very popular. Mounted with 2 (4) bolts.

• Quick release.

The design is equipped with a mechanism that allows you to fold the tow bar frame. The coupling ball is removed. For transporting trailers of small load capacity.

There is no need to try to save money and purchase a trailer hitch with a smaller load capacity. The use of such a product may result in deformation or destruction of the vehicle body structure with subsequent repairs. You can purchase a suitable towbar in specialized stores, where specialists will provide all the necessary advice. They will also send you to a specialized car service center for quick and high-quality installation work.

Installation of a certified trailer hitch on a VAZ 2107

Installation can be done by the car owner himself. But this can lead to deformation of body elements during operation. By seeking the help of licensed professionals with the necessary tools and skills, negative consequences can be avoided.

For installation work you will need:

• drill;
• a set of drills of various diameters;
• set of wrenches;
• pliers.

Installing a tow bar on a VAZ 2107 involves performing the following steps step by step:

• Drive the vehicle into the inspection hole;
• Place the towbar from below to the bottom of the car;
• Secure the ends of the cross beam using bolts and washers in the bumper mounting brackets or in the towing eyes;
• Mark with chalk the locations for drilling holes for attaching the longitudinal beam brackets;
• Drill technological holes and treat them with an anti-corrosion compound;
• Fix the longitudinal beam brackets using bolts with washers and nuts, reinforcing plates;
• Check the tightness of all bolts;
• Check whether the design of the trailer hitch interferes with the operation of the vehicle's systems and mechanisms.

It is also important to know 5 nuances about connection:

Look at the picture of the towbar connector. Switching off will not be particularly difficult, especially if there is a universal component element, which is a towbar connector. It is very convenient to make the connection if the plug and socket match the connectors. Accordingly, a seven-pin socket must be connected to a seven-pin plug. In this option, you can make a normal connection, do not forget to combine the required sockets with the corresponding sockets.

Connecting the towbar socket to the electrical wiring of the VAZ 2107

The basic set of towbars does not include an electrical package. It must be purchased separately.

The socket body is mounted in a special bracket on the towbar. It must be sealed. The socket contacts are tightly recessed into the sockets. Be sure to check the condition of all threaded connections on this kit.

It is recommended to connect the towbar wiring harness in the rear light unit, through the trunk. Upon completion of work, it is necessary to test for the absence of connection errors.

For the VAZ 2107, seven-pin (7 pin) connectors of the European type (RF) are most often used.

1. Place the towbar wiring in a corrugated tube;
2. Disconnect the car battery contacts;
3. Remove the carpet from the luggage compartment floor;
4. Punch a hole in the rubber plug of the trunk floor and pass the trailer hitch wires through it;
5. Connect the wires from the connectors of the towbar to the wires of the standard wiring of the VAZ 2107;
6. The contacts are connected by soldering or using crimp clips;
7. Fix the harness on the body with insulating tape or plastic ties;
8. To eliminate errors in the operation of the electrical wiring of the vehicle, it is recommended to include a Smart Connect matching device in the circuit;
9. Test the operation of new connections. Return the cover to the trunk floor.

If the trailer plug and the towbar socket have a different number of contacts, there are 7/13 or 13/7 adapters.

Pay attention to the quality of the existing fuses, since connecting a trailer will increase the load on the vehicle's electrical wiring. The trailer has its own optical devices:

• Parking lights.
• Stop lights.
• Turn signals.
• Registration number lamps.
• Fog lights.
• Reversing light.

Features of material selection

You can find a wide range of protective films online and in regular car dealerships. They may have different characteristics and vary in cost. In fact, all this is a wrapping material designed to protect body elements from defects and premature wear.

Popular solutions include 3M, SunTec, Llumar and Hexis films. The products are universal, that is, they are used on various cars:

• Skoda Octavia;
• Daewoo Lanos;
• Chevrolet Niva;
• Nissan Qashqai;
• Toyota Corolla;
• Ford Focus;
• Lada Largus;
• VAZ 2110;
• Chevrolet Captiva;
• Skoda Rapid;
• Nissan Sentra, etc.

Experts and simply experienced motorists advise paying attention to several basic parameters when selecting

A wise choice will initially allow you to obtain a material of good quality and with decent performance characteristics. Therefore, the protection will last longer and more reliably. You won’t have to remove the film soon and think about gluing a new coating.

I strongly do not recommend using low-quality film. Even if you glue it well, the effectiveness will be too low. Your time and energy will be wasted.

A good film for protecting car thresholds from wear is selected according to the following parameters.

• Material of manufacture. It is optimal to take polyurethane products. They serve for a long time, protect well from aggressive influences and mechanical wear;
• Layering. High-quality products have 3 layers, no less. The more there are, the thicker the film will end up;
• Color. The bulk are colorless or transparent. This allows you not to change the appearance of the car. But there are also decorative options. The choice is yours.

When choosing coatings, keep in mind that the manufacturer offers material in different lengths and widths. Choose so that you don’t have to glue one threshold together from several pieces of film.

Is it necessary to register a tow bar for a VAZ 2107?

The manufacturer assumes that the trailer will be transported by a VAZ 2107 vehicle (Operation Manual, section “Passport data”), so the car owner can install additional equipment without registration.

The vehicle identification plate is located on the bottom shelf of the air duct box.

The first number is the total permissible weight of the vehicle, the second is the permissible weight with a trailer.

Combining the above, we understand that it is enough to fulfill two conditions under which the towbar does not need to be registered with the traffic police:

• The installation of the trailer hitch is carried out during serial production at the plant. For VAZ 2107 this is not relevant.
• The manufacturer has provided for the possibility of installing a towbar in the operational documentation. The towbar must have a passport and certificate .

How to connect power

To connect the wire and the trailer socket, you need to find a special hole in the bottom of the trunk. If this is not the case, then we do it with a drill. At the same time, think carefully about this issue so that you don’t have to make another hole later.

Next, we fix the socket on the towbar, then we pull the wire through the drilled hole at the bottom of the trunk and connect it to the socket.

That's all, now we have finished the work of installing the towbar. Now you are the owner of a tow hitch that you made yourself. And now you can easily use a trailer to transport heavy and bulky cargo in your car outside the city, to the country.

Traffic police requirements for towbars in 2021

On July 1, 2022, new requirements for registration of changes (tuning) made to the design of cars came into force. Innovations negate the dubious benefits of using homemade towbars. For towbars, they only apply to non-certified towbars. The presence of such a trailer hitch on a VAZ 2107 will entail administrative penalties. To avoid this, the driver will need to undergo a certification procedure in an accredited laboratory (for a fee), or, as an option, dismantle the structure from the car body.

Parts, materials and tools for the manufacture of trailer hitches

To make a towbar with your own hands you will need:

• Welding machine.
• Angle grinder (grinder). Cutting and cleaning discs.
• Protective glasses.
• Drill.
• Drill.
• Steel ball on a hook. Its diameter depends on the trailer manufacturer.

The hitch for a trailer made in Europe must have a ball with a diameter of 50 mm. The ball for the “Americans” comes in two options: with a diameter of 2″, that is, 50.8 mm, or 17/8″, which is equal to 53.975 mm. For a Russian-made trailer, its diameter is exactly 50 mm as for a European one.

You also need to have:

• A piece of steel pipe with a cross section of 50 × 50 mm and a length of slightly more than one and a half meters.
• Two strips of 5 mm thick sheet steel measuring 300 × 70 mm and another pair of the same thickness measuring 200 × 70 mm, as well as a piece of 2 mm thick steel sheet measuring approximately 120 × 120 mm for the socket bracket.
• Bolt M 10 × 1.25, length 80 mm with nut - 2 pcs.
• Bolt M 12 × 1.25, length 50 mm with nut - 6 pcs.
• Screws with nuts for fastening the socket (M 3 or M4, about 40 mm long).
• Socket.
• Multi-colored stranded copper insulated wires and PVC electrical tape.

On registration of a towbar, the installation of which is not provided by the manufacturer

If a towbar is installed on a car, but there is no documentation for it, the driver’s procedure is as follows:

• If there is a marking, contact the specified manufacturer and ask to send documents for the product;
• If it is impossible to determine the brand of the vehicle, make an appointment with the local traffic police department to coordinate changes in the design of the vehicle;
• Complete and submit an application for a preliminary examination of an existing product;
• If the decision is positive, receive a certificate with the result of the examination carried out on the basis of an accredited laboratory;
• Pass a technical inspection of the car;
• Pay state fees;
• Re-issue the vehicle vehicle (a note about the installation of the vehicle vehicle must be entered in the “special notes” column).

To obtain a certificate you must present the following documents:

• device certificates;
• a completed preliminary examination report;
• technical safety assessment protocol;
• application for permission to make design changes (with a note of a positive decision);
• receipts for payment of state fees;
• diagnostic card;
• STS and PTS for a car;
• identification document of the car owner (citizen's passport).

This certificate must be presented along with your license and registration certificate.

If it is clear that the towbar is clearly homemade (welded to the body, secured in an unintended place, of non-standard size, etc.), it is better to get rid of such a product yourself.

Penalty for violations when installing a tow bar

The Code of Administrative Offenses of the Russian Federation (Article 12.5) stipulates the moments when a fine will be issued:

1. The device is not registered.
2. The design interferes with the identification of the state license plate.
3. The vehicle is driven with a towbar installed, but without a trailer.

The structure must be folded when moving. The tip of the product should not protrude too much beyond the dimensions of the bumper.

If one of the violations is detected, a traffic police officer has the right to issue a fine of 500 rubles. Repeated violation - a fine of 5 thousand rubles. Deprivation of a driver's license for a period of 1 to 3 months is applied. Failure to comply with the order to eliminate the violation will result in the cancellation of the vehicle registration.

To reduce the time spent on proceedings with the traffic police inspector, it is recommended to carry the VAZ 2107 Operating Manual and documents for the tow hitch in the glove compartment. The OSAGO policy must contain a note indicating the permitted use of a car with a trailer.
