Product Advantage
Authoritative certification and strict quality control
Our Front Shock Absorber L is fully certified to IATF 16949:2016 (automotive quality management standard) and complies with QC/T 491-2018 (China’s shock absorber industry standard). Every unit undergoes 100% factory testing, including 20+ performance checks (damping force, sealing tightness, etc.), with a pass rate of 99.8%. This ensures consistent quality that meets global automotive aftermarket requirements.
Precision Damping Technology for Stable Performance
As a precision-engineered front shock absorber, it features a multi-stage damping valve design that adapts to 0.13-1.04m/s piston speeds—covering daily commutes to rough roads. It reduces body roll by 35% and vibration transmission by 40% (tested under ISO 18571 standards), maintaining tire contact with the road for safer, smoother driving.
High-Durability Materials & Weather Resistance
Crafted with corrosion-resistant steel housing (double-layer galvanization + electrophoretic coating) and a nitrided piston rod, this front shock absorber L endures 480-hour salt spray tests (exceeding ISO 9227 standards) and operates stably at -40℃ to 80℃. It withstands 300,000+ durability cycles, far beyond the industry average of 200,000 cycles.
Long Service Life & Low Maintenance
With a projected service life of 120,000km (verified via accelerated life testing), this high-durability front shock absorber reduces replacement frequency by 30% compared to ordinary models. Its sealed oil chamber uses high-temperature resistant hydraulic oil (viscosity index ≥140), avoiding oil leakage and ensuring consistent performance over time.
Direct Replacement & Easy Installation
Designed as a direct-replacement front shock absorber, it matches original mounting dimensions with an installation error of ≤0.02mm—no modifications needed. We provide a 24-hour technical support service for installation guidance, and each unit comes with a 24-month warranty, solving post-purchase concerns for buyers.

Product Uses
Here are specific application scenarios of Shock Absorber:
1.Daily Urban Commuting
Ideal for vehicles navigating city roads with frequent stops, speed bumps, and uneven pavements. Its ≥85% vibration reduction rate (ISO 18571-tested) minimizes driver fatigue, while stable damping at low piston speeds ensures smooth rides during daily commutes.
2.Rough & Rural Road Conditions
Suitable for areas with gravel, dirt, or unpaved roads. With 300,000+ durability cycles (ISO 19474), it withstands repeated impacts, and the corrosion-resistant coating (480-hour salt spray test, ISO 9227) prevents rust from mud or moisture.
3.Commercial Load-Bearing Scenarios
Works for light commercial vehicles carrying moderate loads. Its 3.5 MPa maximum operating pressure maintains damping stability under load, avoiding excessive body sag and ensuring consistent handling—critical for delivery or utility vehicles.
4.Extreme Climate Regions
Performs reliably in frigid (-40℃) or hot (80℃) areas. The high-temperature resistant hydraulic oil (viscosity index ≥140) prevents viscosity changes, while the sealed chamber avoids oil leakage, adapting to harsh weather conditions.
5.Aftermarket Maintenance & Replacement
Serves as a direct-replacement part for worn shock absorbers. With ≤0.02mm mounting error (CNC standard), it requires no modifications, reducing repair time. Backed by a 24-month warranty, it’s a trusted choice for repair shops.
6.Performance-Oriented Upgrades
Fits users seeking better handling (e.g., weekend drivers). Its adjustable 1:1.3-1:1.6 compression/extension ratio lets users fine-tune damping, enhancing stability during sharp turns or sudden lane changes without compromising comfort.
Product Operate Guide
For optimal use, have the shock absorber installed by IATF 16949-certified repair personnel (avoids improper fitting). Post-installation, check mounting tightness every 10,000km. Avoid exceeding its 3.5MPa max operating pressure (e.g., overloading). Clean the outer coating monthly to maintain corrosion resistance (480-hour salt spray-tested). If abnormal noise/vibration occurs, stop use and inspect—this preserves 120,000km+ service life.
