Spec Clutch SF743 Stage 3 Clutch Kit

The SPEC SF743 Stage 3 Clutch Kit is engineered for heavily modified street and race engines that demand more than a stock clutch can deliver. Despite its high-performance design, the Stage 3 retains sufficient daily drivability with a comfortable pedal feel and quick, confident engagement — making it a versatile choice for drivers who push their vehicles hard on and off the track.

Built around a high clamp pressure plate, the Stage 3 features a 4 or 6 puck carbon semi-metallic friction disc with a high-torque sprung hub assembly for smooth, controlled power delivery. The 6 puck configuration is standard on most applications; a 4 puck disc can be specified at time of ordering for applications where it is preferred. The kit includes the clutch disc, pressure plate, release bearing, and installation tool kit — everything needed for a complete clutch replacement.

The carbon semi-metallic friction material delivers excellent wear characteristics under both low and high stress conditions, providing long service life even in demanding applications.
