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.

Like the DCT oil pan, the plastic OEM hydraulics cover is prone to fatiguing from heat cycling; not ideal considering the important parts that reside behind it. And also like it's oil pan sibling, the Fall-Line hydraulics cover uses a bespoke Viton O-Ring that resides within a clever internal channel. Viton O-Rings, due to their exceptional resistance to temperature extremes (-20°F to 400°F operating temp) and low gas permeability, have incredible aging characteristics and therefore eliminate the need for regular replacement.
