Product Introduction
The Differential Assembly 3873501323 / 3553500227 / 3873505923 is designed for Mercedes-Benz and European heavy-duty truck rear axle systems. It is used to distribute torque between the left and right drive wheels while allowing different wheel speeds during turning, helping improve drivetrain stability and reduce axle gear stress.
Manufactured with a durable differential housing, precision-machined gears, and high-strength internal components, this differential assembly provides reliable torque transmission, smooth gear engagement, and long service life under heavy-load transportation conditions. It is suitable for axle repair, differential replacement, fleet maintenance, and European truck spare parts supply.
