SPEC Stage 1 clutch kits are designed for street, drag race, drifting, road race, rally, pulling, and autocross use. They feature integrally molded carbon-Kevlar based, high performance organic linings that offer smooth engagement and excellent life. These linings have an integrally bonded steel backing for strength under high clamp loads and temperatures. Hubs are double-sprung with spring cover reliefs for flexibility and heat-treated components for strength and durability.

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.
