Spec Clutch SF363 Stage 3 Performance Clutch Kit

The Spec Clutch SF363 Stage 3 Clutch Kit is the ultimate street/strip clutch solution built for heavily modified street and race engines that demand serious torque capacity without sacrificing everyday drivability. Engineered for drivers who push their vehicles hard across a wide range of performance disciplines, the Stage 3 delivers aggressive engagement with a comfortable pedal feel and sharp, confident shifts.

At the heart of the kit is a high-clamp pressure plate paired with a carbon semi-metallic friction disc — the leading puck-style clutch design in the industry for its combination of drivability, service life, and torque capacity. The high-torque sprung hub and disc assembly absorbs driveline shock and provides smooth, streetable engagement even under demanding conditions. The kit ships complete with a release bearing and installation tool, so everything needed for a full clutch replacement is included.

Key Features:

• High-clamp performance pressure plate for increased torque holding capacity
• Carbon semi-metallic friction material — superior heat resistance and torque capacity
• 4 or 6 puck configuration — 6 puck is standard on most applications; 4 puck available by request at time of ordering

The Stage 3 strikes the balance between race-ready performance and real-world street manners, making it the go-to choice for high-powered builds that see both daily use and track duty.
