Spec Clutch SM753 Stage 3 Performance Clutch Kit 6-Puck Carbon Semi-Metallic

The Spec Clutch SM753 Stage 3 Clutch Kit is the ultimate street/strip solution for heavily modified and high-performance engines demanding aggressive torque capacity without sacrificing daily drivability. Engineered for drivers who need a clutch that can handle the abuse of performance driving while remaining comfortable enough for regular street use, the Stage 3 delivers confident engagement and strong wear characteristics under both low and high stress conditions.

At the heart of this kit is a carbon semi-metallic 6-puck sprung hub disc — recognized as the benchmark for puck-style clutch performance in drivability, service life, and torque capacity. The disc features a double-sprung hub with spring cover reliefs for added flexibility, while heat-treated internal components provide the strength and durability required for demanding applications. A high-clamp pressure plate maximizes clamping force to keep pace with elevated power levels.
