BMW Drivetrain Parts for BMW E21 320i M10 1.8L

Clear BMW chassis

Please ensure your correct model is selected

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. Revshift Performance Engineering is a high-performance parts manufacturer with a focus on quality, reliability, and performance. 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.

As BMWs age, and from spirited use, the shift linkage in the manual transmission will become worn. This selector rod joint is one of the main pieces in the shift linkage but is often overlooked when installing a new shifter or rebuilding the original linkage. This knuckle is the piece that connects the linkage to the internals of the transmission, therefore, it's vital in completing smooth and crisp shifts. Our selector rod kit includes the pieces to replace the transmission selector rod joint and restore its action to a new feel.

In addition to helping restore shifting feel, this piece is required in many short shift kits and selector rod upgrades. The original joint on your car may be the wrong size or shape to work with the new selector rod.

This kit includes part numbers 25117503525 - selector rod joint, 23411466134 shift linkage pin, 4 x 25111220439 washer .
