As an engine’s horsepower and torque is increased, a performance clutch is needed to transfer the engine’s power into motion. With a poor clutch disc, the drive train will not be able to grab hold of the extra power generated. When this happens, you will experience clutch slippage and poor engagement when shifting through gears at high RPMs.

ACT Modified Street clutch discs are designed to withstand high powered applications. ACT Modified Street clutch discs are designed for performance while maintaining the smooth gear engagement. For street riding, the ACT Modified Street clutch disc is the next level up in performance from ACT Stock Street clutch disc. ACT Modified Street clutch discs feature the moderate high copper-content friction lining among the 3 available ACT Street clutch disc series. This friction lining allows better heat tolerance to help prevent warping of mating surfaces and sustain performance.
