Product Introduction
S11-2905010 High-efficiency ISO-certified Reliable Shock Absorber for Chery
This shock absorber is precisely engineered to fit Chery models, crafted with mature manufacturing expertise and strictly compliant with international standards such as ISO 17286 and ECE R90. Equipped with a finely tuned damping system, it responds to road conditions within 0.1 seconds, absorbing over 80% of residual spring vibrations to significantly enhance driving stability and ride comfort. Made from high-quality wear-resistant materials and validated through rigorous durability tests, it can extend the service life of suspension components by 30,000-50,000 kilometers, making it a reliable OE-level replacement option.
Product Advantage
International Standard Compliance & Professional Manufacturing Experience
This Chery shock absorber is manufactured in a facility with 15+ years of automotive suspension experience, strictly adhering to ISO 17286 and ECE R90 standards. Every unit undergoes 3 rounds of quality inspections (material strength, damping performance, corrosion resistance) before leaving the factory, with a product qualification rate of 99.8%. It fully meets OE specifications, ensuring seamless compatibility with Chery vehicles.
High-Performance Damping System for Stable Driving
Equipped with a precision-tuned hydraulic damping core, the shock absorber responds to road undulations within 0.1 seconds. It can absorb over 85% of residual spring vibrations, effectively reducing body sway during cornering and braking (body roll amplitude decreased by 30% compared to ordinary shock absorbers). This technology significantly enhances driving stability and prevents premature wear of suspension parts, making it an ideal OE-level shock absorber replacement.
Wear-Resistant & Corrosion-Resistant Material for Long Service Life
The outer cylinder is made of cold-rolled seamless steel with electrophoretic coating, which has a salt-spray resistance of 500+ hours (far exceeding the industry average of 300 hours). The piston rod uses chrome-plated stainless steel with a surface roughness of Ra 0.02μm, reducing friction by 25% during operation. The shock absorber’s service life reaches 80,000-100,000 kilometers, 40% longer than standard aftermarket shock absorbers.
Temperature-Resistant Oil Seal for All-Condition Adaptability
The oil seal adopts imported nitrile rubber with high temperature resistance (-40℃ to 120℃), maintaining excellent sealing performance even in extreme climates (such as cold winters or hot summers). It effectively prevents oil leakage—test data shows that after 10,000 cycles of simulated extreme temperature operation, the oil leakage rate is 0. This ensures the Chery shock absorber maintains stable performance in all driving environments.
Enhanced Comfort with Optimized Vibration Isolation
Through 100+ times of road test adjustments, the shock absorber’s damping force is optimized to match Chery’s chassis characteristics. It filters out small road vibrations (e.g., gravel roads) while retaining proper road feedback, improving ride comfort by 35% (based on user experience surveys). Whether driving on urban roads or rural rough roads, it provides a balanced combination of comfort and handling.
Easy Installation with Complete Accessories
Each shock absorber comes with a full set of installation accessories (including mounting bolts, washers, and dust covers) that meet OE size standards. The mounting points are precision-machined with a tolerance of ±0.05mm, allowing mechanics to complete installation in 30 minutes or less (saving 20% of installation time compared to non-OE compatible products). It is a cost-effective and time-saving solution for Chery suspension maintenance.

Product Uses
Here are specific application scenarios of Shock Absorber:
1.Urban Daily Commuting
In busy city traffic with frequent starts, stops, and potholes, the Chery shock absorber’s 0.1s rapid response filters 85% of road vibrations. It reduces body jolts when passing manholes, improving ride comfort—90% of urban users report less fatigue after 1-hour commutes, making it ideal for daily use.
2.Rural & Rough Road Driving
For gravel or dirt roads in rural areas, its 500+ hours salt-spray resistant outer cylinder and high-strength piston rod withstand stone impacts. Tests show it maintains stable performance after 5,000km of rough road driving, with no oil leakage or structural damage, solving suspension wear issues on unpaved roads.
3.Extreme Climate Conditions
From -40℃ cold winters to 120℃ hot summers, the shock absorber’s imported oil seal keeps sealing tight. In cold regions, it avoids damping oil solidification; in hot areas, it prevents oil thinning. Data proves 98% stable operation in extreme climates, suitable for global Chery users.
4.Long-Distance Highway Travel
During long highway drives (500km+), its optimized damping force reduces body sway at high speeds (30% less roll than ordinary shocks). It also lowers suspension part wear—after 10,000km highway testing, suspension component wear rate dropped by 25%, cutting maintenance costs for long trips.
5.Commercial Vehicle Usage
For Chery vehicles used for small cargo transport, the shock absorber’s 80,000-100,000km service life and 1 million+ compression-rebound resistance handle frequent load changes. It maintains stable damping even with 500kg loads, ensuring cargo safety and reducing vehicle maintenance downtime by 30%.
Product Operate Guide
Pre-Installation
CheckUnpack the Chery shock absorber and verify no damage (e.g., oil leaks, dents) — confirm the product matches OE part specs via the label. Check accessories (bolts, washers) are complete; use a torque wrench to test bolt tightness (preferred torque: 35-45 N·m) to avoid installation issues.
Installation
TipsInstall per automotive repair standards (SAE J2538): Secure the upper/lower mounting points first, then adjust the shock absorber to align with chassis holes. Avoid over-tightening bolts (may deform parts); after installation, press the vehicle body up/down 3-5 times to activate the damping system.
Post-Installation
TestTake a 5-10km test drive: Check for abnormal noises (no creaks/rattles) and stable handling. Use a vibration tester to confirm vibration absorption rate ≥80% (meets factory standards). Recheck bolt tightness after 100km of use to ensure long-term reliability.
