Spec Clutch SM515 Stage 5 Clutch Kit - Drag Race & Pulling

The Spec SM515 Stage 5 Clutch Kit is purpose-built for extremely modified drag race and pulling applications, as well as any build requiring a slipper clutch or progressive torque-induced engagement. This is a competition-grade, race-only clutch system engineered to handle the brutal demands of high-horsepower, high-torque powerplants where street clutch kits simply cannot survive.

Important: Due to the highly specialized nature of the Stage 5, Spec strongly recommends consulting with a Spec technical advisor prior to ordering. Each kit is best configured to your specific application, power level, and intended use.

Kit Includes:

• High-clamp pressure plate (adjustability available on select applications)
• Rigid iron disc assembly
• Release bearing
• Installation tool kit

Key Features:

• Extreme clamp load — designed for maximum torque capacity in race environments
• Rigid iron disc — provides direct, unforgiving power transfer ideal for drag and pulling use
• Progressive torque-induced engagement — compatible with slipper clutch setups
• Custom configuration available — tunable to your specific build requirements

Intended Use: Drag Racing, Pulling

Note: This clutch is not street-friendly due to harsh engagement characteristics. It is intended exclusively for closed-course competition use.
