Spec Clutch SB043 Stage 3 Performance Clutch Kit

The SPEC SB043 Stage 3 Clutch Kit is engineered for heavily modified street and race engines that demand high torque capacity without sacrificing daily drivability. Featuring a comfortable pedal feel and quick, predictable engagement, the Stage 3 delivers excellent wear characteristics under both low and high-stress driving conditions.

At the heart of this kit is a carbon semi-metallic puck disc — available in a 4-puck or 6-puck configuration (6-puck is standard on most applications; 4-puck available by request) — paired with a high torque sprung hub and disc assembly. The double-sprung hub design features spring cover reliefs for added flexibility, while heat-treated internal components provide long-term strength and durability.

Kit Includes:

• High-clamp performance pressure plate
• Carbon semi-metallic 4 or 6-puck friction disc (6-puck standard)

All SPEC clutch products are designed, hand-built, and tested in the U.S.A., making the Stage 3 a trusted choice for performance drivers who demand both track capability and street manners in a single clutch system.
