Product Introduction
L3001100B1 Durable Reliable Precision Steering Knuckle for Chery
Product Advantage
Crafted with CNC machining (tolerance ≤0.02mm) and cold forging, this steering knuckle matches Lifan’s original specifications flawlessly—no modifications or adjustments needed. Our 8 years of OEM manufacturing experience for Lifan ensures 100% compatibility, helping 500+ distributors achieve zero post-installation complaints. A top pick for installers prioritizing time and accuracy.
Made from SAE 4140 high-strength forged steel (965MPa yield strength—45% stronger than cast iron), it survived 1000+ hours of fatigue testing (simulating harsh road conditions). Third-party reports confirm 18% higher impact resistance than industry norms, minimizing breakage risks in potholes or heavy loads. Built to outlast standard parts.
Every unit undergoes 100% CMM (Coordinate Measuring Machine) inspection (covering 20+ critical dimensions) with a defect rate <0.01%. Dual ISO 9001 & IATF 16949 certifications, plus zero recalls in 3 years, validate our commitment to consistency. Distributors trust us for worry-free inventory—no quality claims to handle.
Unique triangular reinforcement ribs distribute steering force evenly—handling 25% more lateral load than traditional designs. Reduces steering system “play” (looseness) by 15%, improving responsive, precise handling. This safety-focused design is why we’re approved by Lifan’s original equipment suppliers.
While matching OEM quality, this steering knuckle offers 15–20% better value than Lifan’s genuine parts. Our scaled production (50K+ units/month) cuts lead times to 10–15 days, letting you fulfill orders faster without sacrificing durability. Perfect for budget-conscious buyers wanting premium performance.

Product Uses
Here are specific application scenarios of Steering Knuckle:
Ideal for high-frequency, low-intensity use in city delivery vans or ride-hailing cars. With its SAE 4140 forged steel construction (965MPa yield strength), it withstands 120,000+ km of stop-and-go traffic without deformation. Third-party data shows fleets using this knuckle report 30% fewer steering-related repairs vs. generic parts—backed by 500+ fleet clients praising its “set-it-and-forget-it” reliability.
Suited for agricultural vehicles or light off-road machinery navigating potholes, gravel, or uneven surfaces. Tested to survive 1,000+ hours of simulated off-road stress (ISO 16750-4), its triangular rib design distributes lateral loads 25% better than standard knuckles. A 2022 field trial with 100+ rural transport units recorded zero cracks or misalignment—even after 6 months of daily rough use.
Engineered for trucks or trailers carrying 10+ tons of cargo over long distances. Its quenched & tempered surface resists fatigue from continuous steering inputs, validated by 1 million-cycle fatigue testing. Logistics partners report 99.8% uptime over 500,000 km, attributing it to the knuckle’s “no-wear” performance under heavy loads—critical for minimizing costly roadside breakdowns.
A go-to for independent repair shops replacing worn-out original knuckles. With ±0.02mm dimensional tolerance (CMM-inspected), it matches legacy specs perfectly—no drilling or grinding needed. Data from 200+ workshops shows install time drops by 40% vs. aftermarket alternatives, boosting technician efficiency and customer satisfaction with “like-new” steering response.
Preferred by global auto parts wholesalers for its consistent quality. IATF 16949-certified production (defect rate <0.01%) ensures every batch meets tight tolerances, reducing return rates to <0.5%. Distributors note 15% faster turnover vs. competitors, thanks to our 10–15 day lead times and zero quality claim history over 3 years.
Product Operate Guide
Start by cleaning mounting surfaces and inspecting for debris—prevents misalignment. Use a calibrated torque wrench to fasten bolts to 85-95 N·m (our tested optimal range), ensuring even pressure. Align with factory positioning marks (±0.02mm tolerance guaranteed), avoiding forceful hammering. Post-install, test steering for smooth operation; our data shows this process cuts post-installation issues by 30%. Always refer to service manual for final checks—8 years of OEM support validate this workflow for worry-free performance.
