Spec Clutch SD653 Stage 3 Performance Clutch Kit

The SPEC Stage 3 Clutch Kit (SD653) is engineered for heavily modified street and race engines that demand maximum holding capacity without sacrificing daily drivability. Featuring a comfortable pedal feel and quick, precise engagement, the Stage 3 is the ideal choice for drivers who push their vehicle hard on and off the track.

Built around a high-clamp pressure plate and a 4 or 6 puck carbon semi-metallic friction disc, this kit delivers aggressive clamping force combined with excellent wear characteristics under both low and high stress conditions. The 6 puck disc configuration is standard on most applications, while a 4 puck disc can be specified at the time of ordering for smoother engagement preferences. A high-torque sprung hub and disc assembly helps dampen driveline shock for added longevity.

Key Features:

• High-clamp performance pressure plate for increased torque capacity
• Carbon semi-metallic 4 or 6 puck friction disc (6 puck standard on most applications)
