SPEC Stage 4 clutch kits are solid hub versions of their Stage 3 clutches. Each hub is solid with eight rivets and the assembly is heat-treated for strength and durability. They are available in a 3, 4, and 6-puck configurations. Use a 3-puck for the lightest option or a 6-puck for the smoothest engagement. The 4-puck kit is a good compromise for both. Street-drivable in 6-puck configuration, but not street friendly due to the rigid hub.

Note: SPEC flywheel required for proper operation, part number SC57A (Aluminum) or SC7S (Steel).

Break-In Procedure (opens in new tab): A minimum of 450 miles, primarily city driving with frequent stop and go situations, before full throttle engagement, drag launching or speed shifting. Failure to follow these steps will hinder the performance of the clutch and void the warranty. SPEC will not warrant any component failure due to installation errors.
