Spec Clutch SM505 Stage 5 Clutch Kit

The SPEC SM505 Stage 5 Clutch Kit is engineered for the most extreme high-performance applications, including heavily modified drag race engines and competitive pulling builds. This kit is also well-suited for applications requiring a slipper clutch or progressive torque-induced engagement, where precise power delivery under extreme load is critical.

The Stage 5 is SPEC's most aggressive clutch offering and is not intended for street use due to its harsh, abrupt engagement characteristics. For best results, this clutch should be ordered as a custom-configured unit. SPEC strongly recommends consulting with a SPEC technical representative prior to ordering to ensure proper setup for your specific vehicle, engine output, and intended use.
