Science Friction Clutches - American Powertrain
American Powertrain’s Science Friction clutches utilize the most technically advanced friction materials to achieve great performance without a heavy pressure plate to weigh you down. Best of all, we sell most of our clutches direct to the customer with a transmission system so we get tons of feedback from them and use their opinions to constantly improve the line-up. The big box guys ship their stuff on pallets, we ship ours one great clutch at a time. Available for all popular 4, 5 and 6-speed applications behind any classic or modern V8.
Made in USA using scientifically advanced friction materials bonded and riveted to a carrier with captive springs for ultimate rebound control.
Light pedal effort and high tip-in for comfort, carefully balanced and made in Germany to their typically exacting standards. Two stages available for each system.
True Torque Ratings
We live up to our claims with true torque ratings on every clutch kit based on 3600lb curb weight and drag radials. Less tire and weight increases capability. Contact us if you need help choosing the right clutch.
Wide selection of applications for most engine, transmission and performance needs. Compatible with all mechanical and hydraulic release systems.
