Welcome to our store selling car suspension springs. You can buy suspension springs of excellent quality from us. Our store will offer a suspension spring that fits your car. To select springs, you need to select the make, model, body and engine size of your car, and you can also select a spring by the original number. To clarify and make sure that the product you have chosen is correct, you can read in the description of the technical characteristics for the spring Order and buy springs using our catalog number.
The springs are replaced in pairs so as not to disturb the balance of the vehicle. When replacing the suspension springs, it is recommended to pay attention to the condition of the bump stop as part of the shock absorber, since it is he who protects the spring and shock absorber from damage.
When choosing replacement springs, it is important to consult with our manager and choose the ones that are suitable for your car.
Together with our manager, you will learn all the nuances of the selection and operation of springs.
The type of spring is determined by the automaker, and when choosing a replacement option, it is highly desirable to be guided by the rule: the new spring must be completely identical in shape to the original. Our company has all the springs in terms of applicability coincide with the original.
How do suspension springs work?
When the wheel hits a bump, the spring is compressed and transfers the residual vibration to the body. The shock absorber at this moment compensates for the resulting buildup and extinguishes it, converting the mechanical vibration energy into thermal energy. The spring then expands and returns the wheel to its normal position, ensuring its contact with the road surface. The more precisely the interaction of the shock absorber and the spring is calibrated, the better the car is controlled, and the less it loses directional stability on bumps.
Over time, exposed to constant loads, the suspension springs begin to lose their properties – their range of travel is shifted, and the compression / rebound cycle time increases. At the same time, the car begins to lose controllability, and the suspension begins to break through on those irregularities that could have been ignored earlier.
- increase the life of the shock absorbers;
- provide tight and constant contact of the wheels with the asphalt;
- take on the irregularities of the road surface;
- are responsible for maintaining ground clearance under vehicle loads.
Spring wear alarms
An experienced driver will immediately understand if the suspension springs no longer function normally. Here are five main signs of this sore, which will help to identify the problem for not the most experienced car owners: the car sags on one wheel, the difference in the distance from the ground to the arch at the wheels of one axle is visible. On the one side of the axis, the distance is normal, on the other, it is clearly less. Let’s imagine that we are talking about the front axle and you are the driver.
Feeling as if a flat tire, but the tire is completely intact;
The presence of defects in the design of the spring itself. Usually, cracks are visible with the naked eye; extraneous noises, clanks and creaks appear in the suspension;
the vehicle’s ground clearance decreases, under load the vehicle seems to lie on the ground;
the usual parking place has become not so convenient, for example, when the door is opened, it bumps into a curb, or the front bumper suddenly began to crash into it, although nothing like this was observed before;
on the springs themselves, when viewed, traces of rust or mechanical damage are visible.
These are all clear signals to replace the suspension springs. If you postpone the replacement, then you can “get” to the obligatory replacement of shock absorbers and parts of the suspension parts.
Replacing springs with shock absorbers
To change or not is an individual question. The spring can travel 300 thousand km, and maybe 40 If we are talking about an average car, then the approximate service life of a set of springs can be considered a mileage of 120-150 thousand km, which roughly corresponds to two sets of shock absorbers. The third one is strongly recommended to be installed with new springs. This is especially true for cars that are bought on the secondary market. Often, before selling them, the mileage is twisted and the likelihood that the springs are from the factory and the shock absorbers have already been changed is very high.
“The coil of the spring has broken”
How lucky you are. A broken coil can rip a tire, damage a brake hose, or break a suspension part. It can also fly out from under your wheel into the windshield to the one who follows you.
Change the springs if:
- The ground clearance has changed or the car began to sag heavily under load;
- there are traces of corrosion or damage to the paintwork;
- you own a car for a long time and change racks for the third time;
- change shock absorbers on a car that you bought on the secondary market; especially if there is a suspicion of a twisted run.
What can reduce spring life?
The service life of automotive suspension springs depends on many factors that must be considered both at the stage of production and at the stage of direct operation of the vehicle. For example, this is the choice of material (steel of certain grades) from which the springs will be made. It is very important to select a steel grade with the proper parameters, which will subsequently be able to provide the required degree of spring elasticity for a long time. Our company uses only high quality spring steel according to the drawing. Accordingly, the proper quality of wire production is maintained. The technology for the production of springs is observed at all stages of the production process (preparation, winding, hardening, tempering, preparation for painting, painting, etc.). Quality control at all stages. High-quality preparation of the surface of the wire for painting and proper painting. Use for painting a special coating with elastic properties, capable of withstanding various mechanical loads and chemical influences in a wide range of ambient temperatures.
During operation, there are also many factors that can shorten the life of the springs. The most common factor is a violation of the manufacturer’s recommendations for the selection of springs, as well as the choice of unsuitable shock absorbers. Actually, the untimely replacement of “native”, but worn out shock absorbers also negatively affects the resource of the springs. A defective shock absorber does not cope well with damping the vibration of the suspension spring, which is why the spring performs more compression cycles per unit of time.
A suspension shock absorber with more than 50% wear will reduce the life of the suspension spring by about 1.5 times. Of course, constant use of the car in bad road conditions or regular overloading also does not add to the life of the springs. The worse the quality of the road surface, the more “actuation” of the spring occurs per unit of time. The body swing amplitude is also important. With constant mechanical stress, metal fatigue occurs earlier. Damage to the surface of the spring wire (stones, sand, salt or reagents) leads to damage to the paintwork and, accordingly, to the appearance and development of wire corrosion processes.
Various tuning of the suspension, especially handicraft, has an extremely negative effect on the operation of the springs.
In addition, other, not so obvious, operational factors can shorten the life of the suspension springs: a malfunction of the bearing of the upper support, constant uneven loading of the car, the use of tires and discs with different parameters on the same axle, and even incorrect tire pressure.
What consequences for suspension and handling can the wrong spring choice have?
— Illiterate selection of springs
— the primary reason for the deterioration in handling and comfort, as well as an increase in stopping distance.
Purely technically unsuitable springs increase the stress on the valve mechanisms of the suspension shock absorbers, as well as on its other elements. Very stiff springs increase the load on the power elements of the body, which causes distortion, door wedging, cracks on glued glass, etc.
There are frequent cases of incorrect operation and malfunctions in the auxiliary electronic systems responsible for the safe control of the vehicle (ABS and ESP). Problems with “electronic assistants” up to the exit of the ECU in emergency mode. The more modern and “more complex” the car is, the more urgent the problem is.
Installing springs that drastically change ground clearance is another problem for the suspension and other vehicle components. The angles of the wheels are changed. There is an increased wear of tires, silent blocks, drive shafts, CV joints, bearings and wheel hubs, upper shock absorber supports, bumpers and suspension travel stops, as well as shock absorber anthers.
In addition, after installing the suspension springs to increase the ground clearance, the location of the car’s center of gravity changes, which increases the body swing (both longitudinal and lateral), impairs the car’s behavior during maneuvers and negatively affects the control of handling.
