Product Introduction
M11-2905010 Stability-optimized Precision-engineered Certified-compliant Shock Absorber for Chery
Leveraging 15+ years in automotive suspension R&D, our shock absorbers deliver tailored damping for enhanced ride comfort and handling. Crafted with monotube aluminum bodies and gas-charged valving, they suppress 30% more road vibrations vs. standard units (lab-tested at 80km/h). With TÜV-certified 100,000km fatigue resistance, the precision-machined piston ensures ±5% damping consistency across temperatures (-40°C to 85°C). Trusted by 50+ global distributors, this OEM-grade solution balances performance and longevity for diverse light-duty applications. Elevate your inventory with proven, road-ready engineering.
Product Advantage
1. Monotube Gas-Charged Design: Faster Response, Zero Cavitation
Our shocks feature a precision-engineered monotube layout with nitrogen gas charging—solving the “cavitation” (performance drop from gas bubbles) that plagues twin-tube units. Lab tests prove 15% quicker piston reaction to road inputs, delivering instant handling feedback during cornering or pothole impacts. The design also dissipates heat 20% faster, maintaining peak damping on long highway drives. This is the foundation for consistent, sporty performance.
2. ±5% Damping Consistency: Uncompromised in Extreme Climates
Using OEM-grade valving and high-purity seals, our shocks hold tight damping tolerance (+/-5%) from -40°C to 85°C. Third-party testing confirms no degradation after 1,000 cold starts (-30°C) or 500 hours of 90°C heat exposure. This consistency ensures predictable ride quality—whether in freezing winters or scorching deserts—reducing wear on tires, springs, and ball joints.
3. TÜV-Certified 100,000km Fatigue Life: Built for Long-Term Value
Backed by TÜV SÜD certification, our shocks survive 100,000km of simulated abuse (potholes, cobblestones, high-speed cruising). Post-test, wear on critical parts (piston rod, seals) is just 8%—30% better than industry averages. This translates to fewer warranty claims for you and longer-lasting performance for end-users, boosting brand loyalty.
4. 35% Higher Vibration Suppression: Comfort Meets Safety
Our proprietary valving targets high-frequency road vibrations (5-20Hz)—the main cause of driver fatigue and poor tire contact. Compared to generic aftermarket units, we suppress these vibrations by 35%, reducing cabin noise by 20% at 80km/h (independent test data). Drivers enjoy a smoother ride, while improved tire grip enhances safety on wet or uneven roads.
5. Corrosion-Resistant Anodized Aluminum: Outlast Steel by 2X
Crafted from aircraft-grade anodized aluminum, the shock body resists rust 2x longer than steel—even in coastal salt environments. The scratch-proof hard-anodizing protects internal components, extending service life to 150,000km under heavy use. This aligns with EU REACH and North American emissions standards, making it a compliant choice for global distributors.

Product Uses
Here are specific application scenarios of Shock Absorber:
1. Urban Daily Commuting: Balancing Comfort & Noise Reduction
Ideal for stop-and-go city traffic, our shocks suppress 35% of high-frequency road vibrations (5–20Hz) from potholes and speed bumps. Independent tests show 15% lower cabin noise at 60km/h vs. generic units, reducing driver fatigue. With ±5% damping consistency across -10°C to 40°C (typical urban temps), they maintain plush yet controlled rides—trusted by 50+ fleet operators for daily-use vehicles.
2. Cross-Regional Highway Transport: Stability at High Speeds
Engineered for long-distance hauls, the monotube design ensures 20% faster piston response during lane changes or sudden steering inputs. At 120km/h, it cuts body roll by 25% (SAE J1100 testing), enhancing safety. TÜV-certified 100,000km fatigue life means zero performance drop even after 15,000km/week—perfect for logistics fleets prioritizing uptime.
3. Unpaved/Rough Roads: Protecting Components & Payload
On gravel, dirt, or damaged pavements, our shocks reduce wheel hop by 40% and suspension articulation stress. Third-party data confirms 20% less tire wear over 50,000km—critical for off-road delivery or agricultural support vehicles. Hard-anodized aluminum bodies resist stone chipping, cutting maintenance costs for operators in rural areas.
4. Extreme Climate Zones: Performance in -40°C to 85°C
For fleets operating in freezing winters or desert heat, the shock’s viscosity-stable fluid maintains damping force within ±7% across temperature extremes. Cold-start tests (-30°C) show full functionality in <10 seconds—no “soft shock” delays. Adopted by 30+ Arctic/African transport companies for year-round reliability.
5. High-Frequency Commercial Use: Low Failure, High ROI
Designed for taxis, ride-hailing, or delivery vans (avg. 50,000km/year), our shocks boast <1% failure rate after 100,000km (TÜV field validation). Reduced piston rod wear (thanks to chrome plating) cuts replacement intervals by 50%, boosting fleet profitability—backed by 80% repeat orders from commercial buyers.
Product Operate Guide
Pre-Install: Match threads (M14×1.5) and stroke (320mm) to your suspension—avoids fitment issues.
Install: Tighten with a torque wrench to 15-20N·m (OEM spec)—prevents seal damage from over-tightening.
Maintain: Monthly, check for leaks/scratches; every 10k km, test rebound (≤2 bounces post-press = proper function, TÜV-guideline).
