Product Introduction

The 3913320201 Steering Knuckle is an important steering and suspension component used in the front axle system of Mercedes-Benz SK and Beiben NG80 HL6 / HL7 trucks.

The steering knuckle is installed between the front axle beam, king pin assembly, wheel hub, and steering linkage system. Its main function is to support the front wheel assembly, transfer steering force, and allow the wheels to rotate according to driver input while maintaining accurate wheel positioning.

The steering knuckle works together with components including:

• Front axle beam
• King pin kit
• Wheel hub assembly
• Steering arm
• Tie rod assembly
• Brake components

During heavy-duty truck operation, the steering knuckle is continuously subjected to vehicle weight, steering forces, braking loads, vibration, and road impact. Wear, cracks, or deformation of the steering knuckle may result in steering play, uneven tire wear, abnormal front axle noise, and reduced driving stability.

The 3913320201 steering knuckle is manufactured using high-strength forged steel materials with precision machining technology. The reinforced structure provides excellent mechanical strength, fatigue resistance, and accurate fitment with front axle components.

Designed according to OEM specifications, this steering knuckle provides direct replacement compatibility for Mercedes-Benz SK and Beiben NG80 HL6 / HL7 front axle systems. It is widely used for front axle repair, steering system overhaul, fleet maintenance, and truck chassis rebuilding projects.

Each steering knuckle undergoes strict quality inspections including material strength testing, dimensional accuracy inspection, king pin bore measurement, machining surface inspection, and assembly fitment verification to ensure reliable performance and long service life.
