2905220-J08 Noise-Reducing​​ Long-Lasting Vehicle-Specific​​ Shock Absorber for Great Wall Motor

Product Introduction

2905220-J08 Noise-Reducing Long-Lasting Vehicle-Specific Shock Absorber for Great Wall Motor

Product Advantage

1. Exceptional Durability & Long-Lasting Sealing

Our shock absorbers are built with high-carbon steel piston rods, precision-ground and hard chrome-plated to a hardness exceeding HV650, providing superior wear and corrosion resistance. Combined with an innovative triple-lip sealing system (including a Teflon oil seal), they effectively prevent oil leakage, ensuring lasting, stable performance. Rigorous testing, including 1000-hour salt spray tests and over 500,000 cycles of fatigue endurance tests, validates a service life far exceeding that of standard market products, significantly reducing your clients' replacement frequency and long-term ownership costs.

2. Precision Damping Control & Driving Comfort

Featuring a Computer-Aided Engineering (CAE) optimized valve system, our shock absorbers provide precise control over damping force. Whether on smooth highways or rough, uneven roads, they deliver optimal response speed and energy absorption. The use of low-viscosity, anti-foaming hydraulic oil ensures minimal performance fade (less than 15%) across an extreme temperature range of -40°C to 120°C, effectively eliminating "aeration" and guaranteeing a smooth ride and excellent road grip at all times.

3. Optimized Internal Structure & Heat Dissipation

These shock absorbers feature a high-pressure nitrogen gas charge (stable at 25-30 Bar), which significantly suppresses oil foaming and rapidly absorbs high-frequency vibrations. The monotube design offers a larger oil capacity and a more efficient heat dissipation area. Compared to traditional twin-tube designs, this results in a temperature rise reduction of over 20% during continuous operation. This ensures consistent performance and enhanced safety on long journeys or under heavy loads by effectively preventing performance fade due to overheating.

4. Stringent Quality Assurance & Global Standards

Every single shock absorber undergoes 100% performance testing before leaving the factory, ensuring its damping force curve deviates by less than 5% from design specifications. Our manufacturing system is certified under the ISO 9001 Quality Management System, and our products comply with internationally recognized strict standards. We back our quality with a long-term warranty of up to 3 years or 100,000 kilometers, providing global distributors and end-users with the confidence to purchase, supported by authoritative certifications and reliable data.

Technical Parameters

Product Uses

Here are specific application scenarios of Shock Absorber:

1. For Daily Commuting & Urban Driving

Experience a noticeably smoother and quieter ride in city conditions. Our shock absorbers are optimized to effectively dampen high-frequency vibrations from rough pavement, potholes, and speed bumps. This translates to reduced cabin noise and enhanced driving comfort for daily errands and school runs. By maintaining consistent tire contact with the road, they also contribute to improved steering response and safety during frequent stop-and-go traffic.

2. For Challenging & Unpaved Roads

Engineered for resilience, these shock absorbers provide reliable performance on poorly maintained or unpaved roads. The robust monotube design and high-pressure nitrogen charge prevent performance fade from overheating, effectively managing large impacts and sustained vibrations. This ensures vehicle stability and control, protecting both the chassis and cargo from the wear and tear associated with demanding driving environments.

3. For Load-Carrying & Towing Needs

When your vehicle is carrying heavy loads or towing, standard shock absorbers can quickly overheat and sag, compromising safety. Our units feature reinforced construction and a precisely calibrated valve system to provide superior support and damping force under load. This minimizes body roll and suspension bounce, ensuring stable braking and confident handling for a safer journey with added weight.

4. For Restoring Original Performance on Worn Vehicles

Over time, factory-installed shock absorbers wear out, leading to a vague steering feel, increased braking distance, and uneven tire wear. Our direct replacement units are designed to restore, and often exceed, the vehicle's original ride quality and handling. By replacing worn components, you effectively renew the vehicle's safety margins and driving dynamics, making it feel tight and responsive again.

5. For Long-Distance & Highway Travel

Ensure fatigue-free driving and optimal high-speed stability on long journeys. These shocks excel at providing excellent damping control on highways, where stability and precise handling are paramount. The advanced internal design minimizes performance degradation over long, continuous drives, giving drivers confidence and control during extended travel at cruising speeds.
