Product Introduction
The 3913300019 King Pin Repair Kit is an important front axle steering repair component used for Mercedes-Benz SK heavy-duty trucks.
The king pin system connects the steering knuckle and front axle beam, allowing the front wheels to rotate smoothly during steering operation while supporting vehicle weight and steering loads.
The repair kit is mainly used to replace worn king pin system components, including:
- King pin
- King pin bushings
- Thrust bearings
- Sealing components
- Locking components
The king pin repair kit plays an important role in maintaining correct steering geometry and reducing excessive clearance between the steering knuckle and axle beam. The OEM number 3913300019 is listed as a Mercedes-Benz king pin set applicable to SK/MK/NG series axle systems.
During heavy-duty truck operation, the front axle steering system is continuously exposed to vehicle weight, steering forces, braking loads, vibration, and road impacts. Wear of the king pin components may cause steering looseness, uneven tire wear, abnormal front axle noise, and reduced driving stability.
The 3913300019 steering king pin repair kit is manufactured using high-quality alloy steel and wear-resistant bushing materials with precision machining technology. The components are designed to provide accurate fitment, smooth steering movement, and reliable service performance.
Designed according to OEM specifications, this repair kit provides direct replacement compatibility for Mercedes-Benz SK trucks and is widely used for front axle overhaul, steering system repair, fleet maintenance, and commercial truck refurbishment projects.
Each repair kit undergoes strict quality inspections including dimensional inspection, material verification, surface finish checking, and component matching testing to ensure reliable installation and long service life.
