Product Advantage
1. High-Strength Material & Anti-Corrosion Performance
Forged from 120 ksi high-tensile alloy steel, this joint resists deformation under heavy loads—critical for suspension durability. Its electroplated zinc-phosphate coating passes 1,000-hour salt-spray testing (ASTM B117), 30% better than industry norms, preventing rust penetration in humid/salty environments. Backed by 8+ years of OEM supply experience, we ensure consistent material quality to avoid premature failure.
2. Precision Machining for Flawless Fit
Manufactured via CNC precision forging with ±0.5° angular tolerance, this joint aligns perfectly with steering knuckles/control arms. Compliant with ISO 16231-3 standards, its tight tolerances eliminate play—reducing steering wobble and ensuring responsive handling. Our automated inspection checks 100% of units for dimensional accuracy, minimizing installation errors for mechanics.
3. Superior Fatigue Resistance
Rigorous testing exceeds OEM requirements: this joint withstands 1.2 million fatigue cycles (vs. ISO 16231-3’s 1 million), simulating 150,000+ km of real-world use. Lab data confirms no cracks/loosening even at -40°C to 120°C—ideal for extreme climates. For fleets or daily drivers, this means fewer replacements and lower long-term costs.
4. NVH Reduction & Driving Comfort
Engineered with a low-friction polyurethane boot and precision-ground raceways, this joint cuts road noise/vibration by 25% vs. generic parts. The boot’s double-lip seal prevents debris ingress, maintaining lubrication and reducing wear—drivers enjoy smoother, quieter rides. Tested in urban/highway conditions, it balances comfort with durability.
5. Global Compliance & Traceability
All units meet ECE R124/SAE J1394 safety standards, with full batch traceability for regulatory compliance. Our IATF 16949-certified factory implements end-to-end QC—from raw material testing to final load checks—ensuring every joint meets global market demands. Eliminate compliance risks for multi-region distributors.

Enthusiasts seeking sharper handling choose this joint for its ±0.5° angular tolerance—matching OEM precision to improve steering response. Durable enough for spirited driving yet refined enough for daily use, it enhances dynamics without compromising longevity.
Product Operate Guide
First, inspect the joint and mating components for wear—replace if cracked or debris-filled. Clean mounting surfaces with isopropyl alcohol (removes grime for precise alignment). Torque fasteners to OEM-recommended 18-22 Nm (validated by our 8+ years of OEM installation experience to avoid over/under-tightening). Finally, lubricate the boot lip with silicone spray to seal out moisture. Follow these steps for a secure, long-lasting fit—backed by IATF 16949 quality standards.
