Product Description

Product Introduction

S11-2915010 Smooth Responsive Enhanced Shock Absorber for Chery

This premium shock absorber is engineered for superior driving comfort and vehicle control. Manufactured in our IATF 16949-certified facility with over a decade of OE manufacturing experience, it guarantees direct replacement and perfect fitment.

Each unit undergoes rigorous testing, exceeding 50,000 cycles to ensure durability and consistent performance under various road conditions. Key features include:

Precise Damping: Optimized valve design effectively absorbs road shocks, reducing bounce and noise.
Robust Construction: Corrosion-resistant piston rod and high-grade hydraulic oil for long-term reliability.
Enhanced Safety: Improves tire contact with the road for better stability and braking.

It meets or exceeds OE specifications, offering a perfect balance of comfort, safety, and value

Product Advantage

1. Precision Damping Control with Advanced Valve System

Leveraging a proprietary multi-stage valving technology, our shock absorbers deliver adaptive damping performance across varying road conditions. The precision-machined valve stack, with 0.01mm tolerance, ensures consistent damping force accuracy (±2.5% error rate)—outperforming industry norms (5-8%). Tested on our in-house hydraulic simulation rig, it reduces body roll by 40% during cornering, enhancing vehicle stability. This tech is validated by TÜV Rheinland, guaranteeing optimal control for diverse driving scenarios.

2. Premium Materials & Corrosion Resistance

Crafted from SAE 52100 high-carbon steel for the main body and 7075 aerospace-grade aluminum for the piston rod, our units resist wear and deformation. Surface-treated with a 7μm electroplated chromium layer, they withstand 1,000+ hours of salt-spray testing (ASTM B117) without rust—double the industry average (500 hours). This ensures extended service life even in humid or coastal markets, reducing after-sales claims by 35% for our OEM partners.

3. Rigorous Testing & OE-Standard Durability

Each unit undergoes 2 million compression cycles (simulating 150,000 km) on our fully automated fatigue tester, with zero structural failure—surpassing ISO 16231-2 standards (1.5 million cycles). We also replicate extreme temperatures (-40°C to 120°C) to ensure consistent performance. Backed by SGS-certified data, our shock absorbers match OE fitment tolerances (±0.1mm), making them a drop-in upgrade for aftermarket and replacement needs.

4. Aerodynamic & Heat-Dissipation Design

Engineered with a tapered body and internal heat fins, our shocks reduce oil temperature by 18% under continuous use (from 110°C to 90°C). This prevents viscosity breakdown, maintaining damping efficiency over long drives. Wind tunnel tests show a 12% reduction in air resistance compared to generic designs, lowering fuel consumption slightly for the end-user—an added value highlighted by our distribution partners in fuel-conscious markets.

Product Uses

Here are specific application scenarios of Shock Absorber:

1. Daily Urban Commuting: Smooth Ride Comfort

Ideal for stop-and-go city traffic, our shock absorbers reduce impact harshness by 30% when passing speed bumps or potholes (tested with 50kg load simulating passenger weight). The multi-stage valving system softens damping at low speeds, absorbing 90% of minor road irregularities—critical for passenger comfort in taxis, ride-hailing fleets, and family cars. Backed by SGS feedback from urban delivery partners: "Reduced driver fatigue complaints by 25% after switching."

2. High-Speed Highway Driving: Stable Control

Engineered for sustained speeds (100–140km/h), the gas-charged design minimizes "float" and body sway during lane changes or crosswinds. Tested on a 500km highway loop: lateral acceleration reduced by 22% vs. generic shocks, ensuring sharper steering response. Validated by TÜV for OE-level handling—preferred by logistics fleets and performance-oriented aftermarket installers seeking reliability at speed.

3. Wet/Coastal Regions: Long-Term Corrosion Resistance

In high-humidity or salt-laden environments (e.g., coastal cities, tropical areas), our 7075 aluminum piston rods and 7μm chromium plating withstand 1,000+ hours of salt-spray testing (ASTM B117)—double industry averages. A Southeast Asian distributor reported "80% fewer corrosion-related returns"after 18 months of use, making these shocks a top choice for marine-adjacent markets.

4. Off-Road Light Terrain: Rugged Durability

For gravel roads or mild off-roading, the double-tube gas-charged structure resists damage from impacts and debris. With a 2-million-cycle fatigue rating (ISO 16231-2), they outlast standard shocks by 40% in rough conditions—tested by an overlanding equipment supplier: "Zero failures during 6-month off-road trials with 50+ vehicles."

5. Aftermarket Upgrades: OE-Matching Fit & Performance

Designed to replace worn factory units without modifications, our shocks match OE mounting tolerances (±0.1mm) and damping curves. A European auto parts retailer noted: "92% of customers report improved ride quality vs. budget brands, with no installation issues."Ideal for garages and DIY enthusiasts seeking reliable, drop-in performance upgrades.

Product Operate Guide

Pre-Installation Prep: Clean chassis mounts/shock threads with alcohol wipes to remove oil/dirt—prevents seal leaks (a top failure cause per our field data). Inspect piston rods for scratches; replace if found.
Installation: Torque upper/lower bolts to 18–22N·m (do not overtighten—causes body deformation). Align oil seals carefully to avoid contamination.
Post-Install Test: Drive first on dry roads at 30–50km/h for 5 mins (lets oil fill the system). Then test normal speeds—stable handling/no noise confirms success.
Maintenance: Check dust boots every 10k km (replace if torn) and avoid hitting potholes >20km/h—extends life by 20% vs. harsh use.
