Are you a looking to rebuild your own transmission and needing some specialty parts to match your application? BD offers a range of rebuild parts kits featuring the same parts we use in our own performance transmissions for the seasoned builder to complete the job. All kits include the basic rebuild parts and gaskets and have the added touches that range from stock HP up to our Stage 4 Master Kit - which is pretty well everything we put in our own transmission rebuilds. Not all multi-disc converters are created equal and with BD's ProForce 3D, less is more. Our in-house CNC machined billet cover is designed to prevent warping and improper balancing. With our cover design, we were able to increase strength while maintaining the factory height. We have engineered the clutch piston and damper assembly for increased strength, while retaining smooth and reliable vibration damping. With self-centering trapezoid clutch teeth design, our clutch packs ensure proper alignment and less wear resulting a longer converter life cycle.
