Spec Clutch SK243 Stage 3 Performance Clutch Kit

The Spec Clutch SK243 Stage 3 Clutch Kit is a high-performance carbon semi-metallic 6-puck sprung hub disc assembly engineered for drivers who demand aggressive engagement without sacrificing daily drivability. Designed to bridge the gap between street use and motorsport competition, the Stage 3 delivers exceptional torque capacity in a package that remains manageable and controllable on public roads.

At the core of the SK243 is a carbon semi-metallic 6-puck disc that has earned a strong reputation among performance enthusiasts for its balance of grip, longevity, and torque handling. The sprung hub design features a double-spring configuration with spring cover reliefs to absorb drivetrain shock and reduce vibration, while heat-treated internal components provide long-term strength and durability under demanding conditions.

The kit pairs the disc with a high-clamp pressure plate that increases clamping force over stock, enabling the clutch to hold more torque without slipping. Everything needed for installation is included in the box.
