Info

The lighter the rotating mass, the faster you can accelerate off the turns. It doesn't get much lighter than this Quartermaster 5-1/2" Drive dual disc clutch!  Simply use with a GM flex plate and bolt to your pre-'86 S/B Chevy crankshaft. 1-1/8" x 10 spline.

Tech Tip:  When installing a new multi disc 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.
