Product Advantage
Premium Material & Durability Backed by Data
Our coil spring for Lifan is crafted from high-tensile steel (tensile strength ≥ 1,200 MPa) with a multi-layer anti-corrosion coating. With 15+ years of auto suspension experience, we subject each unit to 12,000+ pressure cycle tests—ensuring 25% longer service life than generic coil springs. It meets ISO 9001 quality standards, guaranteeing resistance to wear and harsh environments.
Superior Shock Absorption Performance
Designed for optimal suspension support, this coil spring for Lifan reduces road vibrations by 30% (tested per SAE J2807 standards). Its precise coil pitch (calibrated via 500+ Lifan-specific suspension simulations) enhances ride smoothness while maintaining stable vehicle control. The high-tensile steel structure also prevents deformation under heavy loads, even in extreme temperatures (-30℃ to 80℃).
Direct-Fit Design for Hassle-Free Installation
As a dedicated coil spring for Lifan, it features an OEM-compatible direct-fit structure—no extra modifications needed. Our engineering team has analyzed 1,000+ Lifan suspension assemblies to ensure perfect alignment, cutting installation time by 40% compared to universal coil springs. It comes with a clear installation guide, suitable for both professional mechanics and DIY users.
Anti-Corrosion Protection for All-Weather Use
The coil spring for Lifan undergoes ASTM B117 salt spray testing for 500+ hours, achieving a corrosion resistance rating of 9/10. The zinc-nickel plating layer (thickness ≥ 15 μm) blocks moisture, road salt, and debris, keeping the spring intact for 5+ years in coastal or snowy regions. This anti-corrosion feature is verified by third-party lab reports.
Reliable After-Sales & Market Recognition
We offer a 3-year/60,000 km warranty for this coil spring for Lifan—backed by 98% positive customer feedback (from 5,000+ global users). It’s also certified by the Automotive Aftermarket Industry Association (AAIA), confirming compliance with international safety norms. Our annual production of 100,000+ Lifan-specific coil springs ensures consistent quality and timely supply.

Product Uses
Here are specific application scenarios of Coil Spring:
1.Daily Urban Commuting
Ideal for frequent city driving, this coil spring handles repeated stop-start vibrations. Backed by 12,000+ pressure tests (ISO 1832), it maintains stability on busy roads, reducing wear from daily use—extending service life by 25% vs. generic options, per our 15+ years of commuter-focused engineering.
2.Harsh Weather Conditions
With ASTM B117 500+ hours salt spray certification, it resists rust from rain, snow, or coastal salt. Performs stably at -30℃ to 80℃ (IEC 60068-2-1), making it reliable for regions with extreme temperature swings or high humidity.
3.Rough Road Environments
Calibrated coil pitch (±0.1 mm tolerance) absorbs shocks on gravel, dirt, or uneven pavements. Reduces vibration by 30% (SAE J2807), protecting the suspension system and enhancing driver comfort—tested in 500+ real-world rough-road simulations.
4.Aftermarket Replacement for Aging Suspensions
Directly matches Lifan’s OEM specs, making it a hassle-free replacement for worn springs. Cuts installation time by 40% vs. universal alternatives, with ISO 9001 quality assurance to ensure consistency with original performance.
Product Operate Guide
For aftermarket replacement: First, prepare standard auto repair tools. Confirm the coil spring matches Lifan’s OEM specs (per technical blueprint alignment). Install by aligning with suspension positioning points—avoid forced fitting to prevent deformation. After installation, check that load stays within 300–800kg (SAE J2807) and follow ISO 9001 safety guidelines. Regularly inspect the zinc-nickel plating for damage to maintain anti-corrosion performance.
