Purpose and function of the differential

The presented rear axle differential is designed for Mercedes W212 and W207 models, where it is responsible for the precise transfer of power to the rear wheels. The differential with a 2.65 gear ratio provides an ideal balance between acceleration dynamics and comfortable, economical driving at higher speeds. Its rear-mounted position allows for direct integration with the factory suspension and drivetrain system without the need for bodywork modifications.

Benefits of using an original rear differential

Using an original differential in a Mercedes translates into a number of practical advantages:

• maintaining factory handling characteristics and vehicle stability,
• consistent operation with the stock transmission and half-shafts,
• properly selected 2.65 gear ratio, beneficial for daily use and long-distance driving,
• reduced risk of improper fitment compared to aftermarket replacements.

For the user, this means predictable vehicle behavior, correct operation of assistance systems, and a reduction in additional costs associated with fitting other drivetrain components.

Technical characteristics and fitment

The rear differential from this offer belongs to the Differentials group, meaning it is the component responsible for distributing torque between the rear wheels and compensating for rotational speed differences during cornering. The product features dedicated manufacturer markings and interchangeable part numbers, which facilitates verification of compatibility with a specific vehicle equipment version. This allows for precise selection of the differential for a given Mercedes model, minimizing the risk of errors during purchase.

Its position on the rear axle means the component works directly with the driveshaft and half-shafts, which is why maintaining the correct design parameters is so important. The proper gear ratio affects drivetrain refinement, noise levels, and mechanical stress on other components.

Condition, origin, and practical application

The offered differential is a used component, sourced from dismantling, which allows for combining an attractive purchase price with the preservation of the manufacturer's original specifications. This type of component is particularly recommended for:

• repairs following mechanical damage to the rear axle,
• restoring drivetrain efficiency after a failure,
• restoration projects where compliance with the factory configuration is key.

Choosing an original, used differential allows you to maintain the vehicle's character in line with Mercedes engineering standards, while simultaneously reducing costs compared to a new component.

Gear ratio selection and technical knowledge

When selecting a rear differential for a specific car, the correct gear ratio and compatibility with the drivetrain version are extremely important. To better understand how a 2.65 gear ratio affects vehicle behavior, it is worth consulting expert materials. A detailed discussion of the topic can be found in the article Dismantled drive axles and differentials – how to choose gear ratios for your driving style, which describes the relationships between gear ratios, driving dynamics, and driving comfort.
