Spec Clutch SC662-2 Stage 2 Kevlar Clutch Kit

The Spec Clutch SC662-2 Stage 2 Clutch Kit is a high-performance single-disc clutch upgrade engineered for street and performance driving. Featuring a pure Kevlar friction disc with steel backing, this kit delivers the smooth, stock-like daily drivability of a Stage 1 clutch while offering improved torque capacity and extended service life — making it an ideal step-up for mildly to moderately modified naturally aspirated and power-adder builds.

Rated up to 645 ft-lbs of torque, the SC662-2 uses a full-faced or segmented Kevlar disc with a high-clamp pressure plate and a double-sprung hub featuring spring cover reliefs for added flexibility. Hub components are heat-treated for long-term strength and durability. This unit is a direct replacement designed for use with the factory recessed flywheel design — no SPEC flywheel required.
