Bentley Bentayga W12 Left Gearbox Mount 4M0399201L

Part number 4M0399201L is a genuine left gearbox mount designed for Bentley Bentayga W12 petrol models. Manufactured to Bentley specifications, this transmission mounting component provides essential support for the gearbox while helping to reduce drivetrain vibration and movement.

The gearbox mount plays a critical role in maintaining transmission alignment and stability. By isolating vibrations generated by the engine and transmission, it helps improve ride comfort, drivetrain refinement, and overall vehicle performance.

Over time, gearbox mounts can deteriorate due to heat, load, and continuous drivetrain movement. A worn mount may cause excessive vibration, unwanted noise, drivetrain movement, or reduced driving comfort. Replacing it with a genuine Bentley component helps restore factory-correct performance and long-term reliability.

Designed specifically for Bentley Bentayga W12 petrol models, this genuine replacement gearbox mount delivers precise fitment, durability, and the quality expected from original Bentley parts.

Please confirm compatibility with your vehicle before ordering. Professional installation is recommended, and both left and right gearbox mounts should be inspected during replacement to ensure optimum drivetrain support and performance.
