Technical characteristics and 48:11 (4,363) gear ratio

The presented rear axle differential utilizes a gear set with a 48:11 (4,363) ratio, which determines the relationship between the rotational speed of the driveshaft and the rotational speed of the wheels. This configuration is particularly beneficial in commercial vehicles, where the following are important:

• adequate driving force when starting with a load,
• stable behavior at low and medium speeds,
• predictable characteristics during city and suburban driving.

The choice of gear ratio has a direct impact on dynamics, fuel consumption, and drivetrain comfort, which is why using the correct rear axle in a Sprinter W906 is crucial for maintaining factory vehicle parameters.

Purpose and vehicle placement

The differential belongs to the Differentials category and is intended for installation on the rear axle of the vehicle. Its placement in the rear part of the drivetrain means it is responsible for:

• distributing torque to the rear wheels,
• compensating for the difference in wheel rotational speed during turns,
• maintaining the proper geometry of the half-shafts and the rest of the drivetrain.

A rear axle configured in this way is an essential element for maintaining proper traction, especially in a commercial vehicle that often operates with varying loads and in diverse road conditions.

Compatibility and part identification

The offered component comes from the Mercedes manufacturer's range, which facilitates matching it to a specific version of the Sprinter W906 using catalog data. Identification is based on the OEM part number and available interchangeable numbers, which are listed in the technical specifications section. This allows for precise comparison with the axle currently installed in the vehicle and verification of gear ratio compatibility.

The product is in used condition, which in practice means it has been dismantled and is intended for users looking for a solution with a favorable cost-to-functionality ratio, while maintaining the original design of the vehicle manufacturer.

Practical application and gear ratio selection

The rear axle with a 48:11 (4,363) ratio will perform well in configurations where the priority is a balance between load-carrying capacity and driving comfort. In practice, this means:

• more predictable vehicle behavior when loaded,
• appropriate throttle response under typical commercial vehicle operating conditions,
• the ability to maintain parameters close to factory specifications when replacing a worn-out differential.
