Steering Knuckle OEM Maufacturer
Steering Knuckle introduction
Our forged steering knuckles set the benchmark for durability and precision in demanding applications. As a critical load-bearing link in the steering axle, they:
Ensure rock-steady handling and ultra-sensitive directional control, enabling drivers to respond instantly to road inputs.
Carry dynamic front loads and facilitate smooth wheel articulation around the kingpin, even under repeated impact shocks.
Deliver exceptional strength and fatigue resistance, thanks to an optimized alloy composition and our proprietary heat-treatment cycle.
Backed by 24 years of metallurgical expertise, we've perfected every step-advanced forging, precision CNC machining, and 100% non-destructive inspection-to guarantee perfect fit, maximum longevity, and unwavering performance in passenger cars, commercial cars, heavy-duty trucks, mining equipment, buses, and industrial machinery.
Key Features
We manufacture disc and hub steering knuckles with shaft diameters from Φ35 to Φ80-perfect for both passenger cars and commercial vehicles. Our disc knuckles are finish-machined in one pass on our turning-milling centers, guaranteeing:
Coaxial alignment of inner and outer shafts
Precise perpendicularity and flatness of the brake-caliper mounting surface
All parts are forged from premium 42CrMo steel / Forged QT450-QT500 to ensure consistently high quality and durability.
