Action Clutch 1MS Stage 4 Clutch Kit


Action Clutch "1MS " stage 4 clutch kits features a single diaphragm heavy duty pressure plate mated to a metallic sprung disc. This clutch kit is engineered for high horsepower  vehicles that encounter heavy-duty street use and frequent drag/road/drifting racing. The sprung hub provides moderate dampening, rendering the clutch kit much more streetable than a solid disc design. The clutch features a slight increase in pedal pressure, aggressive  engagement, rapid head dissipation, and outstanding hold capacity.

The sprung disc contained in this kit features new technology around the non-exposed encapsulated disc springs versus competitor sprung discs which expose their springs.

Optional disc: 6 puck (shown) or 4 puck
