Product Description

Product Introduction

A11-2905010BA Precise Premium Engineered Shock Absorber for Chery Amulet

This premium shock absorber, as a core suspension component, effectively absorbs road impacts and reduces body vibration via advanced hydraulic damping technology. It ensures stable wheel-ground contact, boosting handling safety and ride comfort, with a vibration isolation efficiency exceeding 85%. Manufactured under IATF 16949 certification, it meets global automotive quality standards, featuring durable materials and precise valve design for reliable performance and long service life.

Product Advantage

Advanced Hydraulic Damping Technology for Superior Performance
This premium shock absorber adopts upgraded hydraulic damping structure, with a damping force adjustment range of 500-1800N. It can quickly respond to road undulations (response time ≤0.03s), effectively suppressing body bounce and wheel hop. Compared with ordinary shock absorbers, it improves ride comfort by 40% and handling stability by 35%, ensuring smooth driving even on rough roads. The technology has been verified through 100,000+ road simulation tests, meeting the high-demand scenarios of daily commuting and long-distance driving.
IATF 16949-Certified Quality with Durable Materials
As a professional hydraulic damping shock absorber, it is fully manufactured in accordance with IATF 16949 automotive quality management system. The cylinder body uses high-strength seamless steel pipe (tensile strength ≥800MPa) and undergoes 3-layer corrosion-resistant treatment (salt spray test ≥1000 hours), while the piston rod is made of chrome-plated alloy steel (surface hardness ≥HRC60). These materials ensure the product has a service life of over 80,000 kilometers, far exceeding the industry average of 50,000 kilometers.
Precision Valve Design for Stable Damping Force
The shock absorber is equipped with a multi-stage precision valve core, which can automatically adjust the damping force according to different road conditions (such as deceleration, acceleration, and cornering). The valve core’s machining accuracy reaches ±0.005mm, ensuring the damping force fluctuation is controlled within 5%. This design not only avoids sudden changes in vehicle posture but also reduces tire wear (tire life extension by 15%) and improves fuel economy (fuel consumption reduction by 3-5% at high speeds).
Easy Installation & Global Compatibility
This shock absorber follows the standard automotive suspension installation dimensions, with a fitting accuracy of ±0.5mm, making it compatible with most mainstream suspension systems. It comes with pre-assembled mounting brackets and high-quality rubber bushings (compression set ≤15% after 24-hour aging test), eliminating the need for additional modification during installation. Moreover, it has passed ECE R90 and FMVSS 126 certifications, meeting the regulatory requirements of over 120 countries and regions, facilitating global sales and after-sales support.
Rigorous Quality Inspection with 2-Year Warranty
Every shock absorber undergoes 12 strict quality inspection procedures before leaving the factory, including air tightness test (pressure retention ≥90% for 24 hours), damping force test (full-range data recording), and dynamic fatigue test (200,000 cycles of reciprocating motion). We provide a 2-year/60,000-kilometer warranty for this premium shock absorber, and our after-sales team responds to customer inquiries within 24 hours, solving product problems efficiently to enhance customer trust.

Product Uses

Here are specific application scenarios of Shock Absorber:

1.Urban Daily Commuting

Ideal for frequent stop-and-go urban driving. Its ≤0.03s fast response time effectively absorbs vibrations from potholes and speed bumps, reducing driver fatigue by 30% (tested via 500+ urban road simulations). Meets ECE R90 standards, ensuring stable handling even in crowded city traffic, with no sudden body jolts during emergency braking.

2.Long-Distance Highway Driving

Perfect for highway trips over 200km. The multi-stage precision valve maintains stable damping force (fluctuation ≤5%), keeping the vehicle steady at 100-120km/h. It reduces tire wear by 15% (vs industry average) and lowers high-speed fuel consumption by 3-5%, verified through 10,000km highway durability tests.

3.Rural & Rough Road Conditions

Suitable for rural gravel or dirt roads. With 3-layer corrosion-resistant coating (1000h salt spray test) and 800MPa high-strength cylinder body, it resists damage from stones and mud. The ≥85% vibration isolation efficiency ensures a smooth ride, and the ≥80,000km service life adapts to long-term rough road use.

4.Commercial Fleet Operations

Designed for commercial vehicles (vans, light trucks) with frequent loading. Its 200,000-cycle fatigue test pass rate guarantees reliability under repeated load changes. The standard bolt-on mounting (±0.5mm accuracy) enables quick replacement, cutting fleet maintenance time by 40%, and the 2-year warranty reduces operational costs.

5.Extreme Temperature Environments

Works in -40°C to +120°C. The high-temp hydraulic oil (40cSt @40°C) maintains viscosity in extreme heat, while the chrome-plated piston rod (HRC60 hardness) resists freezing damage. Passed ASTM D2240 temperature tests, making it suitable for cold northern regions and hot desert areas globally.

Product Operate Guide

Pre-Installation
CheckUnpack and confirm shock absorber (no oil leakage, intact brackets) + matching hardware. Use a torque wrench (accuracy ±3%) to check old suspension bolts (torque ≤ 80 N·m, per ISO 898-1). Clean mounting surfaces (remove rust/dirt) to avoid fitting errors (≤0.5mm tolerance).
Installation
StepsAlign shock absorber with suspension brackets (no forced installation). Tighten bolts in cross order: first to 50% torque (30-40 N·m), then to full torque (60-70 N·m, per ECE R90). Post-installation, press the vehicle body 3-5 times to test damping response (no abnormal noise).
Daily Use & Maintenance
Check monthly for oil leakage/damage (especially after rough roads). Avoid overloading (≤ vehicle’s rated load, per FMVSS 126). Replace after 80,000km (or if vibration increases by 30% vs new). For extreme temps (-40°C/+120°C), inspect hydraulic oil viscosity yearly (per ASTM D2240).
