Mercedes S204 W204 W907 Engine Support Bracket Rear Right O/S A6512230841

Mercedes S204 W204 W907 Engine Support Bracket Rear Right O/S is an original component from the Engines group, designed to provide stable support for the power unit in the rear right section of the engine bay. Engineered for a specific diesel engine code, it ensures proper load distribution and vibration reduction, which translates into smoother engine operation and greater driving comfort.

Purpose and function in the drivetrain

The rear right engine support bracket in Mercedes compact and mid-size class models is responsible for supporting the power unit from the transmission and subframe side. In combination with other mounts and brackets, it creates a system that:

• maintains the engine in the correct position relative to the body and drivetrain,
• transfers loads generated during acceleration, engine braking, and gear shifting,
• limits the transmission of vibrations and oscillations to the body and the vehicle interior. Thanks to its fitment for a specific diesel engine and its location in the rear right zone, the bracket works with factory mounting points, which facilitates installation and preserves the original geometry of the drivetrain.

Compatibility with Diesel engines

The component has been prepared for operation in a Diesel power unit, which is significant due to the torque characteristics and specific vibrations generated by diesel engines. The bracket design is adapted to:

• higher torsional loads typical for diesel engines,
• operation in elevated torque ranges at low RPM,
• cooperation with factory mounts and the subframe intended for the given engine code. As a result, the stability of the power unit is maintained, and the risk of improper alignment or excessive play in the mounting is reduced.

Characteristics of the used component

The bracket comes from a vehicle with mileage typical for an operated car, which allows for an assessment of its behavior in real road conditions. A used component of this type is particularly attractive in situations where:

• mechanical damage to the engine mount has occurred (e.g., after a collision or impact with an obstacle),
• it is necessary to replace only a specific bracket without interfering with other system components,
• maintaining the original geometry and mounting points specified by the manufacturer is a priority. An original bracket from disassembly allows for maintaining the structural integrity of the drivetrain while reducing costs compared to purchasing a new component.

Benefits of using an original Mercedes bracket

Using a factory engine support bracket in the rear right part of the vehicle brings a number of practical service and operational benefits:

• Precise fit – maintaining the correct position of the engine relative to the half-shafts, transmission, and subframe.
• Stable power unit operation – limiting unwanted engine movement during sudden load changes.
• Compatibility with the factory system – no need for modifications, hole adjustments, or the use of additional adapters.
• Consistency with other items in the Engines category – easier planning of further service work within the drivetrain. For workshops and users, this means shorter installation time, predictable vehicle behavior after repair, and the ability to maintain the factory operating parameters of the drivetrain.
