Spec Clutch ST184 Stage 4 Clutch Kit

The SPEC ST184 Stage 4 Clutch Kit is engineered for heavily modified, high-performance engines demanding maximum torque transfer and instantaneous clutch engagement. Built for the track, not the street, this Stage 4 kit delivers aggressive clutch feel and uncompromising holding power where it counts most.

At the heart of the kit is a high-clamp pressure plate paired with a 3, 4, or 6-puck carbon semi-metallic friction disc mounted on a high-torque rigid hub and carrier assembly. This combination minimizes rotational mass while maximizing grip, making it an ideal choice for applications where lightweight drivetrain components provide a competitive advantage.
