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.
Understanding the ACT alphanumeric coding of our products will help as you look through what ACT offers for your application. Here is a quick reference of how twin-disc clutch kits are listed in ACT’s application chart and website.
The first letter of the part number references the number of discs in the clutch kit. In this example, the “T” stands for Twin.
The vehicle make code is usually the first letter of the make and the first letter of the model the clutch kit is made to fit. In this example, the “G” stands for General Motors.
The application code is usually the numeric code of the model the clutch kit is made to fit. In this example, the “04” stands for XXXXXXXXX.
