Spec Clutch SV063 Stage 3 Performance Clutch Kit

The Spec Clutch SV063 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, positive engagement, the Stage 3 delivers the aggressive performance characteristics needed for high-output builds while remaining manageable for street use.

At the heart of this kit is a carbon semi-metallic puck disc paired with a high-clamp pressure plate and a high-torque sprung hub assembly. The disc is available in a 4-puck or 6-puck configuration (6-puck is standard on most applications; 4-puck available upon request), offering excellent friction coefficient, long service life, and strong torque capacity across a wide range of driving conditions. The double-sprung hub design with spring cover reliefs provides flexibility and helps reduce drivetrain noise and vibration, while heat-treated components add strength and long-term durability.

• High-clamp performance pressure plate

Spec clutches are designed, hand-built, and tested in the U.S.A., and SPEC backs their torque ratings — if the clutch fails below its rated torque capacity under proper installation and break-in conditions, SPEC will replace it.
