Introduction

The 3001044-Q402G Master Pin, also known as the steering king pin, is a vital core component of the FAW heavy-duty truck front axle steering system. It acts as the main rotating shaft for the steering knuckle, supporting the front axle load and realizing flexible left and right wheel steering. Bearing vehicle weight, road impact and frequent steering rotation all year round, this master pin is manufactured with high-strength alloy steel and precision heat treatment technology. It features high hardness, strong bearing capacity and excellent wear resistance. It effectively solves common front axle faults such as stiff steering, wheel shaking, tire eccentric wear, steering looseness and abnormal axle noise caused by worn, rusty or deformed king pins. It is a standard OEM replacement part for FAW truck front axle overhaul and chassis maintenance.

Key Features

✅️Exact OEM Matching & Direct Installation 

Produced strictly according to FAW original factory standards with part number 3001044-Q402G. The pin diameter, length, tolerance and assembly thread fully match FAW series heavy-duty truck front axle parameters. No modification is required for quick installation, ensuring perfect assembly accuracy and original steering performance.

✅️High-Strength Alloy Steel Forging 

Adopts premium alloy steel material through integral forging, quenching and tempering treatment. The master pin achieves ultra-high overall rigidity and surface hardness, with strong compression resistance and load-bearing performance. It can withstand full-load weight and long-term road impact without bending, deformation or fracture.

✅️Precision Machining & Flexible Steering 

Adopts CNC fine grinding and smooth surface finishing. The precise roundness and smooth outer surface ensure flexible steering knuckle rotation. It eliminates steering stagnation, heavy steering and inflexible turning, greatly improving driving controllability and steering sensitivity.

✅️Super Wear Resistance & Long Service Life 

Professional surface strengthening treatment effectively reduces friction loss during frequent steering rotation. It resists daily wear, axle vibration and mud-sand erosion, avoiding early looseness and gap enlargement, greatly extending the service life of the front axle steering system.

✅️Stable Chassis Performance & Safer Driving 

Effectively repairs typical front axle problems including wheel shimmy, tire partial wear, loose steering and abnormal front axle noise. It restores chassis stability, improves straight-line driving performance and reduces driving safety hazards during heavy-load transportation.

✅️Cost-Effective OEM Aftermarket Parts 

Factory direct supply with strict hardness and dimensional testing, delivering OEM-grade quality at a competitive price. Widely applicable to FAW series heavy-duty trucks, it is a trusted replacement part for fleet maintenance, repair shops and global spare parts wholesale across Middle East, Africa and Central Asia markets.
