Purpose and function of the differential

The presented differential belongs to the Differentials category and is mounted on the rear axle of the vehicle. It is responsible for distributing torque between the rear wheels and for the correct gear ratio, which translates into smooth starting, stable acceleration, and predictable vehicle handling in corners. Thanks to the factory 2.47 gear ratio, the axle is suitable for cars used both in daily driving and on longer routes, where smooth drivetrain operation is essential.

Construction and fitment for Mercedes

The Mercedes W204 S204 W212 S212 Rear Axle Differential Diff 2,47 Ratio WARRANTY has been constructed specifically for the Mercedes W204 and W212 platforms, which means maintaining factory suspension geometry and correct positioning of the driveshaft and half-shafts. Its placement at the rear of the vehicle allows for direct integration with the existing drivetrain without the need for structural modifications.

Its original Mercedes origin helps maintain consistency with other chassis components and facilitates the selection of appropriate mounts, bushings, and half-shafts. The product has an assigned OEM part number and interchangeable numbers, which allows for precise verification of compatibility with a specific engine and drivetrain version of the vehicle.

Benefits of using a 2.47 ratio differential

Using a differential with a 2.47 ratio in a Mercedes W204 or W212 allows for a balanced drivetrain character. This gear ratio selection promotes:

• lower engine RPM when driving at a constant speed,
• smoother, more comfortable acceleration characteristics,
• stable handling at higher speeds,
• harmonious cooperation with automatic and manual transmissions provided by the manufacturer.

For drivers who value smooth, predictable driving and proper cooperation with factory drivetrain electronics, this differential is a sensible and technically consistent choice.

Characteristics of the used product

The offered rear axle is a used component, sourced from disassembly, which allows for an economical repair of the drivetrain while maintaining the original design. Such components are a popular choice when replacing worn or damaged differentials, where the priority is compliance with factory parameters and reducing service costs.

Thanks to the retention of the original housing and factory mounting system, installation in place of the old axle is usually straightforward for an experienced mechanic, and the entire operation comes down to correctly connecting the driveshaft, half-shafts, and suspension elements.

Gear ratio selection and technical knowledge

When replacing a differential, it is crucial to match the gear ratio to the transmission, engine power, and expected driving style. To better understand the relationships between the axle ratio, acceleration characteristics, and driving comfort, it is worth consulting specialized resources. A detailed discussion of the topic can be found in the article Used drive axles and differentials – how to choose gear ratios for your driving style, which describes definitions, configuration examples, and practical tips regarding used drivetrain components.
