This Chery shock absorber adopts high-density hydraulic oil and a reinforced piston structure. It has passed over 3 million simulated road condition cycle tests (far exceeding the industry standard of 2 million times) and maintains stable damping performance even in extreme environments ranging from -40℃ to 80℃. This effectively extends the product service life and reduces the frequency of replacement for car owners. Its dynamic characteristic fluctuation rate is strictly controlled within ≤5%, ensuring consistent shock absorption effects under different road conditions and providing core protection for driving safety.
As a shock absorber specifically designed for Chery models, the product strictly complies with original factory dimensional parameters and installation interface specifications, allowing direct replacement without additional modifications. It has obtained ISO/TS 16949 automotive industry quality system certification. Each product undergoes double inspections of air tightness and damping force before leaving the factory, with a sealed leakage rate of less than 0.5ml per hour. This avoids the risk of shock absorption failure caused by improper installation or sealing issues and improves maintenance efficiency.
This Chery-compatible shock absorber is equipped with an adaptive damping adjustment system, which can automatically adjust the damping force according to the degree of road bumps. It maintains a soft shock absorption effect on smooth highways to enhance riding comfort, and strengthens the damping intensity on rough roads to suppress excessive body sway and improve handling stability. According to third-party testing, when the vehicle passes a speed bump at 60km/h, the body vibration amplitude of this product is 30% lower than that of ordinary shock absorbers, effectively protecting the vehicle's suspension system and chassis components.
The product shell is made of corrosion-resistant cold-rolled steel plate, which undergoes electrophoretic coating + spray coating double anti-rust treatment. The salt spray test can last for more than 500 hours, effectively resisting erosion from harsh environments such as rain and mud, making it particularly suitable for rainy or coastal areas. The internal oil seal is made of imported nitrile rubber, whose wear resistance is 40% higher than that of ordinary rubber, reducing oil leakage problems caused by oil seal aging during long-term use and further ensuring the long-term stable operation of the shock absorber.
Aiming at the common abnormal noise problem of traditional shock absorbers, this Chery shock absorber adds a mute and wear-resistant coating between the piston and the cylinder barrel, and optimizes the oil passage structure to reduce the flow noise of hydraulic oil. According to laboratory noise testing, the noise value of the product during operation is lower than 45 decibels (far below the industry average of 55 decibels), and there is almost no obvious abnormal noise during vehicle driving, creating a quiet and comfortable riding environment for car owners and improving the product use experience.
We have 15 years of experience in R&D and production of automotive shock absorbers. This Chery shock absorber provides a 2-year or 60,000-kilometer warranty (whichever comes first), far exceeding the industry's 1-year warranty standard. At the same time, we have a professional technical team to provide customers with installation guidance and fault diagnosis support. If the product malfunctions due to quality issues, customers can enjoy free return and exchange services. Currently, the product has served Chery car owners in more than 50 countries around the world, with a customer satisfaction rate of over 98%, making it a reliable Chery shock absorber solution.

Here are specific application scenarios of Shock Absorber:
Its shell resists rust for over 500 hours (per GB/T 10125-2021 salt spray test), and imported oil seals fight aging. Even in rainy, salty air, it prevents oil leaks and rust, ensuring long-term stable performance in high-humidity environments.
Pre-Installation Check
Verify no external damage or seal defects, and ensure interface dimensions match OEM parts (per ISO/TS 16949). Clean the installation area to remove debris—this avoids performance issues from faulty components.
Professional Installation
Have qualified auto technicians install it. Use a torque wrench to fasten bolts to OEM-specified torque (80-120N·m typically) to prevent abnormal noise or oil leaks caused by over-tightening/loosening.
Post-Installation Test
Test-drive 5-10km. Check for abnormal noise and verify damping stability on smooth roads/speed bumps (meeting QC/T 491-2018 standards) to confirm proper function.
Daily Maintenance
Inspect for oil leaks or rust every 10,000km. Avoid overloading to prevent premature wear—this extends the shock absorber’s service life (up to 60,000km under normal use).
