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.

If you've ever bled the clutch hydraulic system on your BMW, you know how frustrating it can be. Designed with both DIY enthusiasts and professional technicians in mind, our clever tool simplifies one of the most notoriously annoying steps in clutch service.

Crafted from high-quality aluminum and finished in a durable black anodized coating, our clutch slave cylinder bleeder tool is built to last. Its function is simple: the adjustable piston rod applies controlled pressure directly to the clutch slave cylinder’s piston, compressing it and reducing its internal volume. By minimizing the amount of air trapped inside the cylinder, bleeding becomes faster, cleaner, and far more effective—no more endless pedal pumping or inconsistent clutch feel. The result is firm, consistent clutch pedal engagement and a smoother overall driving experience, all achieved with less time and effort underneath the car.

Simplifies bleeding the BMW clutch hydraulic system by reducing trapped air in the slave cylinder Eliminates excessive pedal pumping and inconsistent clutch feel Helps achieve firm, consistent clutch pedal engagement Crafted from high-quality aluminum for strength and longevity Durable black anodized finish resists wear and corrosion Designed for both DIY enthusiasts and professional technicians PRODUCT DEVELOPMENT

Our Clutch Slave Cylinder Bleeder Tool was designed, engineered, tested, and quality inspected by our Research and Development team at Turner. Nothing but the highest level of precision and quality through leading-edge product development technology, including FARO laser scanning for reverse engineering and quality inspection, SolidWorks 3D CAD modeling, rapid prototyping utilizing our in-house 3D printer, and rigorous long-term product testing.
