Product Advantage
Oil-Gas Separation Technology for Stable Damping
As a professional oil-gas separation rear shock absorber, it adopts a dual-chamber structure that completely separates damping oil and high-pressure nitrogen. This design avoids oil-gas mixing (a common cause of damping failure) and maintains 350-3000N adjustable damping force. Tested under ISO 12927-2:2015 standards, its response time is ≤5ms, effectively absorbing road impacts and ensuring smooth rides on rough terrains.
Thickened Aluminum Alloy Body for Durability
The main cylinder is made of 6061-T6 thickened aluminum alloy, with a wall thickness of 3.5mm—30% thicker than industry average. Equipped with DU self-lubricating bushings, it reduces friction coefficient to 0.08, minimizing wear during operation. It has passed 1,000,000-cycle durability tests (equivalent to 100,000km of road use) without performance degradation, making it a reliable durable rear shock absorber.
IP67 Sealed Design for All-Weather Protection
The product features a multi-layer sealing system (including fluoro rubber oil seal + dust cover) that reaches IP67 protection level. It can resist water immersion (1m depth for 30 minutes) and dust intrusion, and remains stable in -40℃ to 120℃ extreme temperatures. After 500 hours of salt spray testing, no rust or corrosion occurred, significantly extending the service life of the rear shock absorber.
High-Performance Valve Core for Adaptive Control
Built with a precision-machined stainless steel valve core, it realizes stepless adjustment of damping force according to road conditions. When encountering sudden bumps, the valve core opens 15% faster than ordinary models, increasing damping force by 20% instantly to prevent excessive spring compression. This high-performance rear shock absorber effectively enhances vehicle stability during high-speed driving or emergency braking.
SGS-Certified Quality with 5-Year Warranty
Our rear shock absorber has obtained SGS certification, and each unit undergoes 100% offline testing (including damping force, air tightness, and dimensional accuracy) before leaving the factory. With 15 years of experience in shock absorber manufacturing, we provide a 5-year/150,000km warranty—far exceeding the industry’s 2-year average. This commitment reflects our confidence in product quality and provides customers with long-term peace of mind.

Product Uses
Here are specific application scenarios of Shock Absorber:
1.Urban Daily Commuting
Ideal for frequent city driving with countless speed bumps, potholes, and stop-and-go traffic. Its ≤5ms fast response (meets ISO 12927-2) absorbs sudden impacts from urban road irregularities, reducing driver fatigue. The oil-gas separation tech maintains stable damping, ensuring smooth rides even during 8+ hours of daily commuting.
2.Off-Road & Rough Terrains
Perfect for non-paved roads like gravel, mud, or mountain paths. With 350-3000N adjustable damping force and IP67 dustproof/waterproof protection, it resists damage from rocks and splashes. Passing 1,000,000-cycle durability tests, this rear shock absorber keeps vehicle control stable on bumpy off-road sections.
3.Long-Distance Highway Driving
Adapts to extended highway trips (500+ km/day) with steady performance. The DU self-lubricating bushings (friction coefficient ≤0.08) minimize wear from continuous vibration, while the -40℃~120℃ working range handles temperature changes across regions. It reduces road noise, enhancing driver comfort during long drives.
4.Extreme Climate Conditions
Works in harsh environments: snowy winters (resists freezing with low-temperature oil) and hot summers (prevents oil degradation). 500-hour salt spray resistance (ASTM B117-21) avoids rust in coastal areas with high humidity. This all-weather rear shock absorber ensures reliability in diverse climates.
Product Operate Guide
Install per ASTM D695-15 standards, recommended for professional technicians. Post-installation, adjust 0-10 level damping: 3-5 levels for urban commuting, 6-8 levels for off-roading. Check IP67 seals and bolt tightness (45-65N·m torque) every 5,000km. Avoid hard impacts; if abnormal noise occurs, stop use and inspect promptly to maintain performance and service life.
