Spec Clutch SN852 Stage 2 Performance Clutch Kit - Kevlar Disc

The SPEC SN852 Stage 2 Clutch Kit is engineered for drivers who demand more from their drivetrain without sacrificing daily street manners. Designed to handle mild to moderately modified naturally aspirated engines as well as power-adder builds, the Stage 2 is an ideal upgrade for spirited street driving, drag racing, autocross, and pulling applications.

At the heart of this kit is a full-faced pure Kevlar® friction disc with steel backing, delivering a step up in torque capacity and wear life compared to the Stage 1, while maintaining the smooth, predictable engagement that makes it practical for everyday driving. The 9.875-inch (251mm) disc pairs with a high-clamp diaphragm pressure plate for a firm, confident pedal feel and improved clamping force over stock.
