Action Clutch multi-disc racing clutches are designed for high performance racers who push their vehicles to the limit. The 8.5in 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 won’t require twice the pedal pressure.

Action Clutch’s 8.5” Twin Disc race kits are designed to maximize performance under extreme conditions and are perfect for those looking for reliable power regardless of racing type. With added features like enhanced heat capacity and improved throttle response, these clutches will help you get off that starting line as quickly as possible and keep you running smoothly through the finish line.

At Action Clutch, every kit is quality checked by one of our experienced engineers (with over 60 years of collective experience) and signed off as safe before being released as a finished product. This gives you peace of mind knowing that your Action Clutch will perform consistently every time.

NOTE: Purchasing the wrong type of clutch kit for your specific engine power output can result in premature clutch failure, damage to the transmission and void warranty eligibility.

Using a clutch kit with an unsprung clutch disc on a stock or lightly modified power engine that is daily/street driven vehicle can break the rivets on the clutch disc hub. Unsprung clutch kits are not designed for daily/street use or any constant on/off engagement environment. This can be compared to running a marathon in sandals vs a proper running shoe. If you were to run the marathon ins sandals, you have no cushion or comfort and can cause injuries or wear you down faster than using proper running shoes.
