Spec Clutch SC682 Stage 2 Performance Clutch Kit - Kevlar Full Face Sprung Hub

The Spec Clutch SC682 Stage 2 Clutch Kit is a high-performance replacement clutch designed for mildly to moderately modified naturally aspirated and power-adder engines. It delivers stock-like daily drivability while offering superior wear resistance and higher torque capacity compared to a Stage 1 unit — making it an excellent upgrade for both street-driven builds and performance applications.

Key Features:

• Pure Kevlar friction disc — segmented or full-face design with steel backing for excellent durability and consistent engagement
• High-clamp pressure plate — engineered to handle increased torque loads beyond stock capacity
• Double-sprung hub assembly — spring cover reliefs provide drivetrain flexibility; heat-treated components add strength and longevity
• Complete kit — includes high-torque sprung hub and disc assembly, release bearing, and installation tool kit (where applicable)
• SFI Approved — every Spec clutch kit and flywheel meets SFI certification standards

Intended Use: Street, Drag Racing, Pulling, Autocross
