Spec Clutch SD652 Stage 2 Kevlar Clutch Kit with Pressure Plate, Disc, and Bearing

The Spec Clutch SD652 Stage 2 Clutch Kit delivers the ideal balance of performance and everyday drivability for mild to moderately modified engines — naturally aspirated or power-adder equipped. It is equally well-suited for stock power levels where long service life and smooth street manners are the priority.

At the heart of the Stage 2 kit is a segmented or full-faced pure Kevlar disc with a steel backing. This friction material provides excellent engagement feel and stock-like pedal behavior while offering improved torque capacity and service life compared to a Stage 1 setup. The high-clamp pressure plate increases clamping force over OEM for a more secure hold under demanding conditions, and the high-torque sprung hub disc assembly uses a double-sprung hub with heat-treated components for flexibility and long-term durability.

Kit Includes:

• High-clamp performance pressure plate
• Pure Kevlar friction disc with steel backing
• High-torque sprung hub and disc assembly
• Release bearing
• Alignment tool for easier installation

Recommended Driving Applications:

• Street / Daily Driving
• Drag Racing
• Autocross
• Pulling
