Science Friction Clutches - American Powertrain

Science Friction Clutches

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.
