Product Introduction

The 3463530420 Differential Spider Rear is a key internal component of the rear differential assembly used in Mercedes-Benz and MAN heavy-duty trucks. It is installed inside the differential carrier and works together with differential gears, side gears, planetary gears, and bearings to maintain stable gear operation and efficient torque distribution.

The differential spider rear provides the supporting structure for differential gears, allowing the left and right wheels to rotate at different speeds during turning while maintaining continuous power transmission. This function helps reduce tire wear, improve vehicle stability, and ensure smooth drivetrain performance.

During heavy-duty operation, the differential spider is subjected to high torque loads, repeated rotation, and impact forces. Long-term wear, insufficient lubrication, or excessive operating stress may cause deformation, clearance changes, abnormal noise, or reduced differential efficiency.

Manufactured from high-strength alloy steel through precision forging, CNC machining, and heat treatment processes, the 3463530420 differential spider rear provides excellent mechanical strength, wear resistance, and dimensional accuracy. The precise machining ensures correct positioning of differential gears and reliable operation of the axle system.

Designed according to OEM specifications, this differential spider rear provides direct replacement compatibility for Mercedes-Benz Actros, Axor, NG, SK, Econic, North Benz, and MAN truck axle systems. It is widely used for rear axle repair, differential overhaul, fleet maintenance, and aftermarket drivetrain replacement applications.

Each component undergoes strict quality inspections including material strength testing, dimensional accuracy verification, surface hardness testing, and assembly compatibility inspection to ensure dependable performance and extended service life.
