Technical specifications and intended use

The presented rear axle with differential belongs to the Differentials category and is designed for installation on the vehicle's rear axle. The differential's design allows for proper torque distribution between the wheels, which translates into predictable vehicle behavior during acceleration, engine braking, and cornering. The applied gear ratio balances acceleration dynamics with driving comfort at highway speeds.

Its rear-mounted position means the component works directly with the driveshaft and axle shafts, serving as a key point of the entire drivetrain. A properly selected differential reduces wear on other drivetrain components and improves the overall operating culture of the system.

Benefits of using an original differential

Using an original differential in a Mercedes vehicle ensures:

• Factory fitment to the geometry of the rear suspension and drivetrain, with no modifications required.
• Consistent cooperation with the existing drivetrain, which facilitates diagnostics and maintenance.
• Stable operating parameters under loads typical for commercial and delivery vehicles of this brand.

As a precision-engineered mechanical component, the differential requires structural compatibility with the vehicle. Choosing an original rear axle reduces the risk of issues such as noise, vibrations, or uneven tire wear.

Condition, origin, and practical application

The offered differential is a used component, which allows for a significant reduction in repair costs compared to new OEM parts, while maintaining the factory design. Such components are particularly valued in vehicles used intensively, where a reasonable balance between durability and service costs is essential.

The rear axle with differential is suitable for both standard fleet operation and vehicles working under heavier loads, provided the gear ratio is correctly matched to the specific vehicle version. Before installation, it is recommended to verify compatibility with the vehicle's model, year, and drivetrain configuration.

Gear ratio selection and expert support

The proper selection of the differential gear ratio has a direct impact on driving characteristics – acceleration, engine RPM at a given speed, and fuel economy.
