BD Diesel | Duramax Proforce 3D Torque Converter GM 2001-2016 Allison 1000 | 1071240

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.
