Choosing the Right Clutch
Choosing the correct clutch for your application requires knowing the estimated torque your engine will produce. Once you have an estimate of the torque your engine is producing, we recommend choosing a clutch that will handle at least 10 percent over the torque output of the engine. Torque capacities indicated in the application chart are calculated from pressure plate tests performed at ACT’s facility.
