Spec Clutch ST552 Stage 2 Clutch Kit with Kevlar Disc

The Spec Clutch ST552 Stage 2 Clutch Kit is engineered for mild to moderately modified naturally aspirated and power-adder engines, while remaining an excellent choice for stock power levels where long service life and confident daily drivability are priorities. It strikes the ideal balance between street manners and performance capability, making it well-suited for drivers who demand more from their clutch without sacrificing everyday usability.

At the heart of the Stage 2 kit is a pure Kevlar friction disc with steel backing — a segmented or full-faced design that delivers superior holding power and wear resistance compared to a stock clutch. The Kevlar lining provides excellent drivability similar to the Stage 1, but with notably longer service life and higher torque capacity.

Key Features:

• High-clamp pressure plate for increased clamping force and improved torque transfer
• Pure Kevlar friction disc with steel backing for durability and smooth engagement
• High-torque sprung hub and disc assembly for dampening driveline shock and reducing chatter
• Bearing and alignment tool kit included for straightforward installation
• SFI approved — every Spec clutch kit and flywheel carries SFI certification

Recommended Driving Applications: Street, Drag Racing, Pulling, Autocross

The Spec Stage 2 kit is part of Spec's full performance clutch lineup, which spans Stage 1 through Stage 5 single-disc kits as well as multi-disc Super Twin assemblies, ensuring a solution for every performance level.
