Action Clutch multi-disc racing clutches are designed for high performance racers who push their vehicles to the limit. The 7.25in Twin Disc race kits feature two sintered metallic race discs, formulated in the USA, which offer superior heat capacity and a smoother engagement than any other disc on the market. It also comes with a Ventilated 6061-T6 Billet Aluminum clutch cover design to help reduce overall weight and improve throttle response which is paired with our high strength steel pressure and floater plate. This added clamping force wonÕt require twice the pedal pressure.

Came based on a work buddies recommendation. I was late by 30 minutes, confused my appointment time. But, 10/10 would come back. Came for a Downpipe and midpipe install. Not only was the gentleman accommodating, He ran into some issues, staff helped me out and pointed me into the right direction and got me going! They got my business and wouldn’t go anywhere else again!
