Note: Purchasing the wrong type of clutch kit for your specific engine horsepower output can result in catastrophic clutch failure, damage to the transmission, and void warranty eligibility. Please use the chart below to help narrow down your Action Clutch kit choice.

Example: using a clutch kit with an unsprung disc on a stock/lightly modified powered engine that is street/daily driven can destroy the rivets holding the unsprung disc together. Unsprung discs/clutch kits are not designed for street/daily use or a constant on/off engagement environment. Similar to running a marathon in sandles vs. running shoes.
