About this product

The SB10-XTSS ACT Extreme Performance Street Sprung Clutch Kit is designed for high-powered street cars seeking smooth, reliable engagement with enhanced durability.

The premium organic street disc offers higher copper content for improved heat transfer and steel-backed construction for increased burst strength and durability. Reduced marcel design ensures quicker shift action, complementing the pressure plate. The kit also includes ACT’s patented Monoloc—a one-piece, hardened chrome-moly steel collar that maintains consistent bearing and pressure plate alignment for long-lasting reliability.
