Building your perfect BMW is more than just adding horsepower and stiff suspension. Your drivetrain needs attention in order to deliver power effectively. Most BMWs feature comfortable clutch discs, heavy flywheels, long shifter throws, and open differentials. The drivetrain transmits power to the wheels, but can also be a source of power loss when it is designed for comfort rather than performance. Everything on this page will help you improve your power delivery and driving experience by providing custom Limited Slip Differentials, Short Shift Conversions, Performance Clutch Discs, Lightweight Flywheels, and anything else your BMW needs to be the perfect driving experience.

Revshift mounts are the most durable and reliable mounts on the market. CNC machined billet aluminum flanged ends are embedded deep in the urethane which prevents the isolated ends from separating under extreme loads. Utilizing class 14.9 alloy steel removable screws these mounts will hold your transmission in place for a lifetime. To further ensure the strength of these mounts we form the threads with a forming tap which creates denser and stronger threads in the billet aluminum ends pieces. These mounts have removable screws for ease of installation. We recommend using Loctite on the threads during installation.

Utilizing high-precision machining technologies and their very own Polyurethane Manufacturing Department, every Revshift product is designed, manufactured, and tested in-house at their Detroit, Michigan facility.
