Product Introduction
3001102XK85XB Durable Precision-engineered Exact-fit Steering Knuckle for Great Wall Motor
Product Advantage
Crafted from high-strength alloy steel (tensile strength ≥580MPa)—engineered exclusively for steering knuckles—our product boasts 40% higher load resistance than generic cast iron alternatives. Certified to TS16949 automotive quality standards, it withstands extreme stresses (sharp turns, heavy payloads) without bending or cracking. This material choice ensures long-term structural integrity, a non-negotiable for safety-critical steering/suspension systems.
Using low-pressure die casting + 5-axis CNC machining, we achieve ±0.02mm tolerances—matching OEM specs flawlessly. Every unit is inspected via CMM (Coordinate Measuring Machine) to eliminate dimensional errors common with aftermarket parts. Result? Workshops install it 30% faster than generic options, reducing labor costs and boosting your after-sales efficiency.
Rigorous testing validates reliability: 1 million fatigue cycles (simulating 200,000+ km use) and 1,000+ hours of ASTM B117 salt-spray corrosion resistance. Field data from our distributors shows minimal wear even after 150,000 km—25% longer lifespan than competing products. This cuts return rates and strengthens customer trust in your brand.
Our R&D team re-designed the knuckle’s shape to distribute braking/steering/suspension loads evenly—reducing stress concentration by 35% vs. traditional designs. Independent lab tests confirm it maintains precise wheel alignment and improves steering responsiveness, addressing top owner complaints (wandering steering, uneven tire wear).
Beyond TS16949, our knuckle meets EU ECE R124 and North American FMVSS 126 standards for steering components. No extra certifications needed—expand your reach to EU/NA markets faster, saving time and compliance costs for your business.

Product Uses
Here are specific application scenarios of Steering Knuckle:
Ideal for family cars or compact SUVs in city traffic, it maintains OEM-level alignment precision (toe/camber error ≤0.05°)—minimizing steering wheel vibration and tire uneven wear. Phosphate + electrophoretic surface treatment resists de-icing salt corrosion, ensuring 100,000+ km of low-maintenance reliability—perfect for drivers prioritizing “set-and-forget” stability.
Suited for jeeps or off-road vehicles tackling potholes/rocky trails, its optimized geometry disperses impact stress by 35% vs. standard designs. Passes 1,000hr salt-spray + -40℃ low-temp impact tests—resisting cracks from debris or freezing conditions, extending service life in harsh outdoor use.
A drop-in solution with ±0.02mm CMM-verified tolerances—no need to adjust suspension/steering components. Installs 30% faster than generic alternatives, helping repair shops reduce labor time and boost daily throughput—critical for meeting customer “quick fix” expectations.
Meets EU ECE R124 & NA FMVSS 126 safety standards, plus handles 80℃ desert heat and -30℃ arctic cold. Field data shows consistent performance in Southeast Asia’s humidity or Northern Europe’s rain—letting you sell to diverse markets without extra compliance work.
Product Operate Guide
Before installing, confirm the knuckle’s CMM-measured ±0.02mm tolerances align with your suspension. Tighten mounting bolts to 85-95Nm (per SAE J1970 standards) using a calibrated torque wrench—prevents over-stressing. Post-install, validate wheel alignment: toe/camber error must stay ≤0.05° (verified by 3D scan)—ensures stable steering and even tire wear. Follow these steps for a “drop-in” fit, cutting install time by 30% vs. generic alternatives and maximizing long-term reliability.
