Shock absorbers primarily control the oscillation of springs after shock absorption and impacts from the road. While shock-absorbing springs filter road vibrations, they themselves undergo reciprocating motion. Shock absorbers suppress this spring bounce. If shock absorbers are too soft, the vehicle body will bounce up and down; if they are too hard, they will create excessive resistance, hindering the normal function of the springs. Shi Xiaohui indicated that in suspension system modifications, hard shock absorbers should be paired with hard springs. Spring hardness is closely related to vehicle weight; therefore, heavier vehicles generally use harder shock absorbers. Modifications require continuous experimentation to design optimal shock absorber and spring combinations. Professional modification shops can usually help car owners find suitable pairings.

1. Check if the product offers a 2-3 inch lift requirement. Some products only offer a 2-inch lift, and forcing them to 3 inches can easily cause damage during off-roading.

2. Ensure the shock absorber's central telescopic rod diameter is 16mm or more. This is a basic indicator of strength.

3. Verify that the upper and lower connecting sleeves of the shock absorber are made of high-strength polyurethane. This is crucial for ensuring long-term, high-intensity use, as ordinary rubber cannot withstand high intensity for extended periods.

Shock absorbers are easily damaged parts in vehicle use. Their proper functioning directly affects the vehicle's smooth operation and the lifespan of other components. Therefore, we should ensure shock absorbers are always in good working condition. The following methods can be used to check if the shock absorbers are working properly.

1. Drive the vehicle on a relatively rough road for 10km, then stop and touch the shock absorber casing. If it's not hot, it indicates a lack of internal resistance, meaning the shock absorber is not working. In this case, add appropriate lubricating oil and retest. If the casing heats up, it means the shock absorber lacks oil and needs to be refilled. Otherwise, the shock absorber has failed.

2. Push down firmly on the bumper and release it. If the vehicle bounces 2-3 times, the shock absorbers are working properly.

3. When the vehicle is slowly driving and brakes suddenly, significant vibration indicates a problem with the shock absorbers.

4. Remove the shock absorber, stand it upright, and clamp the lower connecting ring in a vise. Pull and push the shock absorber rod several times. There should be stable resistance, with upward resistance greater than downward pressure. Unstable or no resistance may indicate a lack of oil or damaged valve parts inside the shock absorber, requiring repair or part replacement.

If a shock absorber problem or failure is confirmed, check for oil leaks or signs of old oil leaks.

If there are no oil leaks, check for damage, welding defects, cracks, or detachment in the bushings. If the above checks are normal, further disassemble the shock absorber to check for excessive clearance between the piston and cylinder, cylinder scratches, proper valve sealing, tight valve and seat fit, and whether the shock absorber extension spring is too soft or broken. Repair or replace parts as needed based on the condition of the shock absorber connecting pin, connecting rod, connecting hole, and rubber.

Additionally, shock absorbers may make noise during use. This is mainly due to collisions between the shock absorber and the leaf spring, frame, or axle; damaged or detached cushions; deformed shock absorber dust boots; or insufficient oil. The cause should be identified and repaired.

After inspection and repair, shock absorbers should undergo performance testing on a specialized test bench. When the resistance frequency is 100 ± 1mm, the resistance of the extension and compression strokes should meet the specifications, indicating that the shock absorber is functioning properly.

These shock absorbers have a special rubber cross-section for shear and compression loading, allowing for good axial displacement. The bracket is a low-cost isolator with high load capacity in a compact size, providing a solution for a wide range of applications. This mounting is ideal for trucks, car engines, radiators, etc. The cab mount is equipped with two safety washers to prevent overloading. CN A version features two different radial stiffnesses.
