Product Advantage
Advanced Hydraulic Damping Technology
Our shock absorber adopts upgraded hydraulic damping cores, which efficiently convert vibration kinetic energy into heat and dissipate it in 0.3 seconds. Backed by 15+ years of auto parts R&D experience, the product has passed IATF16949 certification and 500+ hours of extreme environment tests (including -40℃ low-temperature resistance and 70℃ high-temperature stability). It achieves a vibration suppression rate of over 92%, significantly reducing road impact transmission and enhancing driving comfort—making it a reliable high-performance shock absorber for aftermarket needs.
Superior Fatigue Life Performance
Through precision heat treatment of internal components, our shock absorber boasts a fatigue life of over 300,000 cycles, which is 50% higher than the industry average (200,000 cycles). Each unit undergoes 10,000+ dynamic load tests before leaving the factory to ensure no oil leakage or damping failure under long-term use. This data-driven durability ensures customers get a long-lasting shock absorber that minimizes replacement frequency and maintenance costs.
High Adaptability to Multiple Road Conditions
Designed with adjustable damping force, our shock absorber adapts to various road surfaces (paved roads, gravel roads, mountain roads, etc.). The dynamic stiffness error is controlled within ≤2%, which is lower than the industry standard of ≤3%. This stability ensures the automotive suspension system maintains optimal performance at all times, reducing tire wear by 15% and improving vehicle handling—solving the pain point of poor adaptability of ordinary shock absorbers.
Premium Material & Precision Craftsmanship
The shock absorber uses a double-tube structure with high-strength carbon steel cylinders (tensile strength ≥600MPa) and chrome-plated piston rods (plating thickness ≥20μm). It has passed 2000-hour salt spray tests, with corrosion resistance reaching grade 9 (ISO 9227 standard). The seamless welding process of the cylinder body reduces oil leakage risk by 98%, ensuring the hydraulic damping shock absorber maintains stable performance in humid or corrosive environments.
Intelligent Performance Optimization
Equipped with a rapid-response valve core, our shock absorber adjusts damping force within 0.1 seconds when encountering sudden road changes (such as potholes or speed bumps). Test data shows it shortens vehicle braking distance by 8% on uneven roads and reduces body roll by 12% during cornering. This real-time performance adjustment makes it an ideal automotive suspension shock absorber for customers pursuing both safety and driving experience.

Product Uses
Here are specific application scenarios of Shock Absorber:
1.Urban Daily Commuting Scenarios
Ideal for daily travel on city roads with frequent stop-and-go and uneven manholes. Our shock absorber’s 92% vibration suppression rate reduces jolts from road gaps, cutting driver fatigue by 30% during 1+ hour commutes. Its 0.1s damping response also minimizes sudden body 晃动 when passing speed bumps, enhancing ride comfort for urban users—aligning with the high-performance shock absorber’s daily-use advantages.
2.Rural & Unpaved Road Scenarios
Perfect for rural gravel roads or mountain dirt roads where road conditions are complex. With dynamic stiffness error ≤2% (lower than industry standard ≤3%), it maintains stable damping performance on bumpy surfaces. Test data shows it reduces tire wear by 15% compared to ordinary shock absorbers, solving the problem of rapid part damage on rough roads—trusted by users in rural aftermarket markets.
3.Commercial Cargo Vehicle Scenarios
Suitable for light-duty commercial vehicles (e.g., delivery trucks) that carry loads and face long-distance driving. Boasting ≥300,000-cycle fatigue life (50% higher than industry average), it resists wear from continuous load pressure. During 10,000+ dynamic load tests, it showed 0 oil leakage, ensuring stable suspension performance—lowering maintenance costs for commercial fleet operators.
4.Extreme Climate Scenarios
Adaptable to cold regions (-40℃) and high-temperature areas (70℃), as well as coastal humid environments. Passing 500h extreme temperature tests and 2000h salt spray tests (corrosion grade 9), it maintains consistent damping force without performance decay. This makes it a reliable choice for customers in polar, desert, or coastal regions—proving the shock absorber’s environmental adaptability.
Product Operate Guide
Install your shock absorber following ISO 18575 automotive suspension installation standards: fasten bolts to 80-120N・m (check product manual for exact value) to avoid damping failure from loose/tight connections. Inspect every 5,000km for oil leakage or piston rod scratches—prompt repair prevents 30% shorter service life. Avoid long-term overloading (it cuts shock absorber fatigue life by 30%); if driving 异响 occurs, stop to check immediately for stable performance.
