Quarter Master 309390 Details
Quarter Master Friction Disc Packs feature an advanced friction formula developed from rigorous testing and feedback in the NASCAR Sprint Cup Series. The increased torque capacity gives the driver a better clutch pedal feel, thereby improving drivability. Performance is also improved due to the increased coefficient of friction. Each disc pack comes standard in our clutch products and is available with one, two or three discs. They can also be used in competing products using .105″-thick frictions.

Tech Tip: When installing a new clutch, be sure to follow the manufacturer’s instructions for correct set-up. You should also replace the pilot bushing/bearing.
Tech Tip: To extend the life of your expensive racing clutch you should not use it to load the car on or in your trailer. The amount of slippage this causes is worse than a night of racing.
