Product Introduction
M11-2905020 High-response Long-lasting Smooth-riding Shock Absorber for Chery
With 12+ years in suspension R&D, our monotube gas-charged shocks deliver refined damping for balanced ride comfort and handling. Crafted from aircraft-grade anodized aluminum, they suppress 30% more road vibrations (5–20Hz) vs. standard units (lab-tested at 80km/h). TÜV-certified for 100,000km fatigue life, the precision valving maintains ±5% damping consistency across -40°C to 85°C. Trusted by global distributors, this OEM-grade solution blends performance and longevity—ideal for enhancing vehicle stability and reducing component wear. Elevate your inventory with proven, road-ready engineering.
Product Advantage
1. Monotube Gas-Charged Design: Faster Response, Zero Cavitation
Our shocks leverage a precision monotube layout with nitrogen gas charging—solving the “cavitation” (performance drop from gas bubbles) plaguing twin-tube units. Lab tests prove 15% quicker piston reaction to road inputs, ensuring instant handling during cornering or potholes. It also dissipates heat 20% faster, keeping damping peak on long highway drives. This design is trusted by fleet operators for consistent, sporty performance.
2. ±5% Damping Consistency: Stable in Extreme Temperatures
Using OEM-grade valving and high-purity seals, our shocks hold tight damping tolerance (+/-5%) from -40°C to 85°C. Third-party testing shows no degradation after 1,000 cold starts (-30°C) or 500 hours of 90°C heat—critical for drivers in harsh climates. Consistent damping reduces tire/wheel wear and delivers smooth rides year-round.
3. TÜV-Certified 100,000km Fatigue Life: Low Maintenance, High ROI
Backed by TÜV SÜD, our shocks endure 100,000km of simulated abuse (potholes, cobblestones, high-speed cruising). Post-test, piston rod/seal wear is just 8%—30% better than industry averages. This cuts warranty claims for you and extends end-user satisfaction, boosting brand loyalty for distributors.
4. 35% Vibration Suppression: Comfort & Safety Combined
Our proprietary valving targets 5–20Hz high-frequency vibrations (the main cause of driver fatigue and poor tire grip). Compared to generic units, we reduce these vibrations by 35%, lowering cabin noise by 20% at 80km/h (independent lab data). Drivers get a quieter ride; improved traction enhances wet-weather safety.
5. Corrosion-Resistant Anodized Aluminum: Outlasts Steel
Crafted from aircraft-grade anodized aluminum (6061-T6), the body resists rust 2x longer than steel—even in coastal salt environments. Hard anodizing protects internal parts, extending service life to 150,000km under heavy use. Compliant with EU REACH and North American emissions, it’s a safe, sustainable choice globally.

Product Uses
Here are specific application scenarios of Shock Absorber:
1. Urban Daily Commuting: Comfort & Noise Reduction
Ideal for stop-and-go city traffic, our shocks suppress 35% of high-frequency road vibrations (5–20Hz) from potholes. Independent tests show 15% lower cabin noise at 60km/h vs. generic units—reducing driver fatigue. With ±5% damping consistency (-10°C to 40°C), they keep rides smooth. Trusted by 50+ fleet operators for daily-use vehicles, balancing comfort and control.
2. Highway Long-Haul Transport: Stability & Safety
Engineered for 120km/h+ speeds, the monotube design ensures 20% faster piston response for lane changes. SAE J1100 testing confirms 25% less body roll, enhancing safety. TÜV-certified 100,000km fatigue life supports weekly 15,000km runs—perfect for logistics fleets minimizing downtime and maximizing uptime.
3. Rural/Unpaved Roads: Component Protection
On gravel or damaged pavement, our shocks reduce wheel hop by 40% and suspension stress. Third-party data shows 20% less tire wear over 50,000km—critical for off-road delivery or agricultural support. Hard-anodized aluminum resists stone chipping, adopted by rural transport companies for low maintenance costs.
4. Extreme Climates: Year-Round Reliability
For -40°C (Arctic) or 85°C (desert) operations, stable fluid viscosity maintains ±7% damping. Cold starts work in <10 seconds (-30°C)—no “soft shock” delays. Used by 30+ polar/African fleets, it proves performance in harsh conditions without failure—ideal for global distributors.
5. Commercial High-Use Fleets: Low ROI Risk

Product Operate Guide
Pre-install: Match threads (M14×1.5) & stroke (180mm) to avoid fitment issues. Install with a 15-20N·m torque wrench (OEM spec)—prevents seal damage. Maintain: Monthly check for leaks/scratches; every 10k km, test rebound (≤2 bounces post-press = proper function, TÜV-guideline). This routine ensures 100k km of reliable use—backed by our fatigue testing. Simple steps, lasting results.
