Medium & Heavy Duty Truck

Semi Driveshaft Light Duty, Medium Duty, Heavy Duty Trucks, Box Trucks and Diesel Semi Tractor driveshafts take a lot of abuse when used in a commercial application. The heavy loads, high torque loads and varied driving surfaces requires a driveshaft with top quality components, careful attention to weld quality and precision balanced for a smooth ride. Even though it is not required, Action Machine balances our big semi tractor driveshafts to the same tight tolerances as our race car driveshafts. Our philosophy has always been to take care of the folks who are earning a living with their truck. This means building the shaft to last and getting it right the first time.
