    Quarter Master 309391 Details

    Three disc 1-1/16" x 10 spline replacement clutch pack. 

    Tech Tip:  When installing a new clutch, be sure to follow the manufacturers 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.
