The elements of the rear and front suspension of the “seven” provide sufficient smoothness of movement. Despite the presentation of the VAZ 2107 as a “luxury” model, the design of the suspension parts does not differ from the VAZ 2101 (FIAT 124). This also applies to shock absorbers, which do not always do their job well. What is the difference between different types of shock absorbers, which shock absorbers are better to install on a VAZ 2107 - this article is devoted to these issues.
Front shock absorbers VAZ 2107
Front shock absorbers for the VAZ 2107 are not divided into right and left, and have one article number for both sides. As drivers note, these shock absorbers are too soft, and therefore the car body often sags greatly when cornering or when transporting cargo. They serve for a relatively long time. Often VAZ 2107 owners install shock absorbers from Niva. But this is not the best option, since in addition to this, you also need to install springs from the Niva. As a result, the front of the car rises significantly, and on top of everything else, these racks turn out to be much stiffer. And as a result, riding them is uncomfortable.

| vendor code | Rod diameter, mm | Case diameter, mm | Body height (excluding stem), mm | Rod stroke, mm |
| 21012905004, 21012905402 | 12 | 41 | 215 | 112 |
Also, the seven has original front gas shock absorbers under article number 210102905402. They are never installed from the factory, you need to buy and install them yourself. Compared to oil ones, they are a little stiffer, and according to most drivers, more comfortable.
Analogs of front shock absorbers for VAZ 2107
Numerous replacements for the original shock absorbers are very popular among drivers of sevens. The reason for this is higher quality foreign spare parts, and most often at a lower cost. After all, for the price of an original oil shock absorber, you can find a gas analogue, which, as a rule, is more expensive than conventional hydraulic struts. The table shows the most popular oil analogues, as well as one gas one from Kayaba.
| Manufacturer | vendor code | price, rub. |
| KYB | 343097 (gas) | 1300 |
| KYB | 443122 | 800 |
| Hola | S401 | 700 |
| Fenox | A11001C3 | 600 |
What other options are there?
Most drivers leave the standard “original” shock absorbers. Some people install dampers from the Niva - such parts are much stiffer, because the 2121 model was originally designed for poor road conditions.
Gas-oil ones are not particularly popular, but are great for those who drive quite quickly. This is an indispensable part for tuning. Improved comfort. Adjustable shock absorbers are used in sports cars. For ordinary cars, such a solution is impractical.
Rear shock absorbers for VAZ 2107
The rear shock absorber struts are identical in characteristics and design to the front ones. They still have the same significant drawback - excessive softness. Since the VAZ 2107 is often used for economic needs, in particular for transporting various cargoes, overly soft shock absorbers are a problem. Therefore, installing seven shock absorber struts and springs from Niva on the rear wheels is more justified.

| vendor code | Rod diameter, mm | Case diameter, mm | Body height (excluding stem), mm | Rod stroke, mm |
| 21012915402 | 16 | 42 | 310 | 182 |
For the rear wheels there is also an original gas shock absorber, which is not installed from the factory - 21010291500610.
Analogs of rear shock absorbers for VAZ 2107
For the rear suspension of the VAZ 2107, replacements are especially relevant, since in most cases the owners of this car require stiffer shock absorbers.
| Manufacturer | vendor code | price, rub. |
| KYB | 343098 (gas) | 1400 |
| KYB | 443123 | 950 |
| Fenox | A12175C3 | 700 |
| QML | SA-1029 | 500 |
What are the best shock absorbers for the VAZ 2107 to buy? If the car is not actively used for business purposes, and is operated mainly in urban conditions, then stock oil shock absorbers are well suited. In all other cases, many drivers recommend installing shock absorber struts from Kayaba (KYB), oil ones if moderate rigidity is needed, or gas ones if a stiffer suspension is needed.
According to the rating of shock absorbers for the VAZ 2107 on PartReview dated 04/07/20, owners prefer products from KYB. Manufacturers FENOX, Bilstein and Monroe also stand out.
Which manufacturer to choose
In fact, all manufacturers of parts for VAZ cars should be the same, but there is still a difference in driving performance.
Oil shock absorbers from different companies do not differ from each other. It will not be possible to find gas-oil parts made by “our” manufacturers - they are simply not produced. Therefore, foreign companies come to the rescue. The most common companies are:
- Kayaba;
- Sachs;
Here are the most common companies that meet the price/quality criterion. In fact, for domestic classics you can find a list of manufacturers that will be several times larger. If you have not found products from the above brands, before choosing another company, read the detailed information in detail. Forums and all kinds of communities will become faithful assistants in this matter.
When to change shock absorbers on a VAZ 2107?
According to the VAZ 2107 maintenance regulations, shock absorbers are checked, as everywhere else, at every scheduled maintenance. Vary depending on the condition. Symptoms when replacement is necessary are standard - extraneous sounds from the suspension, the car does not hold the road well, the shock absorber struts have begun to leak, etc. As the experience of owners of sevens shows, original shock absorbers last an average of 50-70 thousand km. mileage But this largely depends on the driving style and operating conditions.

Changing shock absorbers on a VAZ 2107
A car shock absorber is a device that provides not only comfort, but also safety for the driver and passengers. Shock absorbers ensure that the car's wheels are firmly pressed against the road surface, resulting in body vibrations being reduced to a minimum. The domestic car VAZ 2107 is equipped with shock absorbers, which are installed in the chassis structure near each of the wheels. Let's look at what it means to replace shock absorbers on a VAZ 2107 in detail.
The importance of the quality of shock absorbing springs
An important element that influences the quality of adhesion of car wheels to the road surface is the shock-absorbing spring, which softens shocks, reduces vibrations and shaking, which accelerate the wear of shock absorbers.
Indicators characterizing the quality of the spring are:
- Rigidity.
- The length is in good condition.
- Length under load.
- The diameter of the rod from which the part is made.
The table shows the characteristics of springs installed on various VAZ car models.
| Spring and car type | Load (kg) | Spring stiffness (kgf/cm) | Normal spring length (mm) | Spring length under load (mm) | Bar diameter (mm) |
| Front spring VAZ 2106, 2107 | 450 | 35.3 | 360 | 232 | 13.13 |
| Rear spring VAZ 2106, 2107 | 305 | 18.9 | 434 | 273 | 12.4 |
| Front spring VAZ 2110, 2114 | 325 | 19.0 | 383 | 211 | 12.9 |
| Rear spring VAZ 2110, 2112 | 325 | 19.7 | 403 | 240 | 11.6 |
| Front spring VAZ 2112 | 355 | 21 | 383 | 211 | 13.2 |
| Rear spring VAZ 2114 | 295 | 17.1 | 418 | 245 | 11.15 |
Replacing springs on cars operating in Russian road and climatic conditions is usually required when the mileage is 100,000 km or more.
When choosing springs, it is necessary to take into account their characteristics and the quality of products from various manufacturers. The design of the spring must correspond to the original one, you should also take into account the general layout of the suspension parts and the dimensions of the shock absorber.
Springs from different manufacturers differ in the type of steel, manufacturing technology, and the quality of the anti-corrosion paint and varnish coating. Combination with unsuitable shock absorbers and incorrect selection of unit parameters accelerates spring wear.
When is it necessary to replace shock absorbers?
Both front and rear shock absorbers on the VAZ 2107 perform the same function. Despite this, these elements differ structurally. The main difference between these elements is the method of fastening, but we will learn more about this when we consider the process of replacing units.
The products in question need replacement in the following cases:
- When the mechanism becomes unusable, that is, it does not have the ability to cushion the car body and smooth out shocks. It is not difficult to detect a malfunction of this mechanism, because in this case it becomes not entirely comfortable in the car interior.
- Presence of oil leaks on the device. You can detect leaks even without removing the product from the car.
Replacing shock absorbers on a VAZ 2107 car
The suspension on VAZ cars of the classic family has certain features and differences from the suspensions installed on modern car models. The design of the suspension on Zhiguli cars has an archaic and heavy design, which inevitably affects the quality characteristics of the stability and controllability of the car. In this connection, there are certain nuances associated with the installation and adjustment of shock absorbers on rear-wheel drive VAZ models.
Due to the design features, the front shock absorber mount on the VAZ 2107-2101 “Classic” is a separate part. The rear dampers on the classics and their fastenings are completely installed on the dependent axle, which negatively affects the stability of the car. That is why it is extremely important to pay attention to the adjustment of shock absorbers and subject the suspension to timely repairs and maintenance.

Today, the next article in the series “Crystal VAZs or typical breakdowns of domestic cars” is dedicated to the “classics”: VAZ-2101, 2103, 2104, 2104, 2105, 2106 and 2107. These cars have been driving along our roads for decades and, despite Despite all the shortcomings that we will talk about, their popularity is still high.
Purpose and design of shock absorbers VAZ 2107
The main purpose of shock absorbers in a car is to smooth out and absorb vibrations (shocks) from the road surface and prevent the transfer of mechanical energy to the car body. Dampers are attached on one side to the power parts of the body, and on the other to the suspension parts (levers, bridge).
The suspension arms are constantly subject to vertical vibrations, ensuring the stability of the car, so shock absorbers in this “bundle” play an important role. When shock-absorbing parts in a car wear out, part of the load is transferred to the suspension and body elements, which greatly affects the service life of the suspension.
The racks are a tubular structure of hydraulic or gas type. Smoothing of vibrations from the road surface in such shock-absorbing struts occurs due to the oil or gas located inside. The rigidity of the struts and the progress of work depend on the speed of movement of the rod in the structure, the viscosity of the oil (gas density) and the settings of the bypass valves.
When hitting an obstacle, the movable rod in the strut structure moves, and the oil (or gas) inside the shock absorber tube moves into a special cavity, thereby smoothing out vibrations from the road surface.
Design features of fastenings
Depending on the car model and the type of suspension installed on the front and rear axles, the types of shock absorbers and their mountings (from torsion bars to the body) vary. All modern dampers (with the exception of air suspension) can be divided into two types according to the type of design:
- classic pipe design with top and bottom bolted fasteners;
- dampers designed for MacPherson-type front suspension.
Dampers are also divided into two types, depending on the damping element used. It could be:
On modern cars, front dampers are often strut-style and are compatible with MacPherson-type front suspension. Since the front suspension on classic VAZ models is a “multi-link”, the mounting under the strut on it will be appropriate. On the front suspension in this configuration, the shock absorber mounting bolt in the upper part is installed on a special shock absorber mounting pad, and the lower part of the strut is attached as standard - to fasteners on the lower arm.
In the rear suspension, the struts are installed similarly to any modern cars. Through standard fastenings in the body (to the upper part) and to a special platform through a silent block (at the lower part) installed on the bridge.
Why is shock absorber wear dangerous?
Failure of shock absorbers leads to a loss of vehicle stability on the road: skidding and rolls occur, and the brakes work worse. With such unstable driving, tires wear out faster, supports break, and other important suspension elements fail, which leads to an increased risk of an accident.
With 50% wear, the braking distance of the car increases by 2 m (if the car is moving at a speed of 50 km/h). That is, worn shock absorbers are just as dangerous as faulty brakes.
The reasons for accelerated wear of shock absorbers can be factory defects, corrosion, accumulation of dirt, temperature and mechanical deformation, and malfunction of other suspension elements.
Signs of shock absorber wear are:
- body swaying during maneuvers;
- skidding on corners;
- sagging of the rear part of the body when accelerating the car and the front part when braking;
- increased sensitivity to road irregularities;
- uneven tire wear, “squealing” when turning and braking;
- vibration of the steering wheel while the car is moving;
- Frequent activation of the ABS anti-lock braking system.
The need for urgent replacement of shock absorbers is also indicated by the appearance of oil leaks on the struts.
If there is obvious wear on one of the shock absorbers (rear or front), it is necessary to change both cylinders at once, since they work in pairs, and their quality most likely deteriorates simultaneously.
Experts advise diagnosing shock absorbers every 20,000 km, and this should be done at a service station where there is special high-precision equipment for this. It is important to remember that it is usually difficult for a driver to “by eye” determine the initial signs of deterioration in the performance of shock absorbers.
How to choose shock absorbers
Choosing shock absorbers is not an easy task, since it is necessary to take into account a number of important factors that will subsequently affect the handling and service life of the car’s suspension. First of all, you need to pay attention to the following points:
- type of racks (gas or oil);
- length;
- permissible loads;
- compatibility with specific brands and models of cars.
The type of struts affects the stiffness of the suspension and its service life. Thus, gas struts are better suited for those drivers who prefer a more or less sporty ride and the most informative and “understandable” steering wheel. Installing oil-filled shock absorbers is more preferable for quiet motorists who use the car to perform everyday tasks.
Oil dampers are softer than gas dampers and provide comfort for the driver and passengers. Gas models are quite rigid, but this is a kind of payment for greater stability of the car on the road.
The length of the struts affects the vehicle's ground clearance. Installation of tuning models of struts with a lowering from -30 to -70 mm has a positive effect on the handling and stability of the car, as the center of gravity is reduced. There are models on the market with both factory length parameters and modified ones.
The permissible load indicator indicates how much the car can be loaded without compromising the condition of the suspension. As a rule, in expensive gas models this indicator is higher, which has a positive effect on the overall condition of the suspension and the service life of its parts.
Features of repair of shock absorber mounts
The designers of VAZ cars of the classic family did not provide for the possibility of serious loads when designing the design of the upper mounts for the rear dampers. Therefore, many car enthusiasts encounter problems when installing rear struts on the upper mounts.
The upper mounts are metal studs secured to the body cross member at the rear of the car. Over time, metal fatigue appears at the fastening points due to the constant loads from the operation of the dampers, so the metal studs often crack and break off, or the fastenings themselves fail.
To solve problems with the upper fastenings, owners of classic Lada cars often resort to replacing the studs with new ones. To do this, holes are cut out at the locations of the fasteners using a grinder and the old studs are removed.
After that, new steel pins and washers are installed in the mounting holes, and the fastening points are securely welded with a welding machine.
You can safely install new shock absorbers on new mounts and not worry about the reliability of the mounts.
