Spec Clutch SB153 Stage 3 Clutch Kit with Carbon Semi-Metallic Disc

The SPEC Stage 3 Clutch Kit (SB153) is engineered for heavily modified street and race engines that demand more than a stock or entry-level performance clutch can deliver. Despite its high-performance capabilities, the Stage 3 maintains sufficient daily drivability with a comfortable pedal feel and quick, positive engagement — making it a versatile choice for drivers who push their vehicles hard both on and off the track.

This kit features a high-clamp pressure plate paired with a 4 or 6-puck carbon semi-metallic friction disc mounted on a high-torque sprung hub and disc assembly. The carbon semi-metallic compound provides excellent wear characteristics under both low and high-stress operating conditions. The 6-puck configuration is standard on most applications, with the 4-puck option available upon request for specific fitments.

Kit Includes:

• High-clamp performance pressure plate
• 4 or 6-puck carbon semi-metallic friction disc with sprung hub
• Release bearing
• Installation tool kit

Intended Use:

• Street
• Drag Racing
• Drifting
• Road Racing
• Rallye
• Pulling
• Autocross

The SPEC Stage 3 is the ideal upgrade for performance-driven builds that require aggressive clutch engagement and high torque capacity without completely sacrificing street manners.
