Product Advantage
Authority-Certified Quality with High-Strength Material
This left rear shock absorber has passed ISO/IATF16949 automotive quality system certification, ensuring compliance with strict industry standards. Its cylinder body adopts high-strength steel with a tensile strength of 510MPa, which is 30% higher than ordinary shock absorber materials. This structure effectively resists deformation under high pressure, laying a solid foundation for long-term stable operation.
Stable Damping Performance with Extreme Temperature Adaptability
Equipped with built-in high-pressure nitrogen and high-performance shock-absorbing oil, the high-pressure nitrogen shock absorber maintains consistent damping force in the temperature range of -40℃ to 120℃. Even in harsh environments such as cold winters or hot summers, it can quickly attenuate vibrations, reducing body bounce by over 40% and improving driving comfort and stability.
Superior Durability Verified by Rigorous Testing
The product has undergone a fatigue test of no less than 3 million cycles, far exceeding the industry average of 2 million cycles. The internal hydraulic buffer device further reduces stress fatigue of components, extending the service life by 50% compared to conventional left rear shock absorbers. This durability ensures long-term reliability for users, reducing replacement frequency and maintenance costs.
Corrosion-Resistant Coating for All-Environment Adaptation
The surface of the shock absorber is treated with black powder coating, which has passed a 720-hour neutral salt spray test (meeting ASTM B117 standards). This coating forms a dense protective layer, effectively resisting rust and corrosion caused by rain, snow, and road salts. It makes the corrosion-resistant automotive shock absorber suitable for various complex road and climate conditions, maintaining structural integrity for years.
Precise Fitment & Easy Installation Design
With CNC precision machining, the shock absorber’s mounting dimensions have an error of less than 0.1mm, ensuring perfect compatibility with most automotive suspension systems. The standardized interface design allows for direct replacement without additional modifications, shortening installation time by 30%. This feature not only improves efficiency for repair shops but also reduces installation difficulty for individual users.

Product Uses
Here are specific application scenarios of Shock Absorber:
1.Urban Commuting Scenarios
Ideal for daily urban driving with frequent starts/stops and traffic lights. The left rear shock absorber effectively buffers vibrations from manhole covers, speed bumps, and uneven road surfaces, reducing body 颠簸幅度 by over 40%. Its stable damping (maintained via high-pressure nitrogen) ensures smooth handling when switching lanes, enhancing ride comfort for daily commutes.
2.Rural & Unpaved Road Scenarios
Perfect for rural gravel roads, dirt paths, or construction zones with large potholes. With a cylinder body made of 510MPa high-strength steel and ≥300k fatigue test verification, it resists impact damage. The shock absorber quickly attenuates strong vibrations from rough terrain, preventing excessive suspension compression and ensuring stable vehicle control, even at low speeds.
3.Long-Distance Highway Scenarios
Suitable for 4+ hour highway drives, where cumulative minor vibrations easily cause driver fatigue. The product’s -40℃~120℃ temperature adaptability keeps damping consistent (variation ≤±8%) even in high-speed wind-heated or cold environments. It reduces vibration transmission to the cabin by 35%, alleviating driver waist/back fatigue and improving long-distance driving safety.
4.Extreme Climate Scenarios
Applicable to regions with heavy rain, snow, or extreme temperatures. Its 720-hour salt spray-tested powder coating resists rust from road salt (in snowy areas) and rain erosion. In high-temperature deserts or frigid winters, the high-performance shock oil maintains fluidity, ensuring the left rear shock absorber operates normally without damping failure, adapting to diverse climate conditions.
5.Light Load-Carrying Scenarios
Useful for vehicles carrying luggage, groceries, or light cargo (e.g., family trips). The shock absorber’s 12,000N maximum load capacity and hydraulic buffer device suppress body sag caused by extra weight (reducing sag by 25%). It maintains balanced suspension height, preventing uneven tire wear and ensuring stable braking/steering when loaded.
Product Operate Guide
For safe use, please have the left rear shock absorber installed by professionals following ISO 18798 installation standards—ensure mounting bolts are torqued to 25-30N·m. After installation, test for smooth damping operation. For daily maintenance, check the shock absorber every 5,000km: inspect for oil leaks, ensure connection parts are tight, and replace if abnormal noises/vibrations occur (avoid self-disassembly, as it may damage internal high-pressure components).
