Find Parts That Fit Your Vehicle

BMW Drivetrain Parts

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.

We all love the ZF 8HP for its lightning-fast shifts, but as many BMW owners discover, it’s not invincible. If you’ve pushed your build past the factory power limits, you’re likely feeling the dreaded "trans slip." Before you spend five figures on a replacement, check out the Hard Parts Kit from Pure Drivetrain Solutions. This kit targets the specific failure points of the 8HP, reinforcing the transmission from the inside out.
