Details:

Each disc pack comes standard in our clutch products and is available with one, two or three discs. Three disc 1-1/8 x 10 spline replacement clutch pack. Disc packs w/ improved friction formula for racing applications. Performance is also improved due to the increased coefficient of friction.

Heavy-duty frictions are utilized for improved durability. Tech Tip: To extend the life of your expensive racing clutch you should not use it to load car on or in trailer. The amount of slippage this causes is worse than a night racing. I have a tilting triple disc clutch, but these Quartermaster discs work well in it.

They can also be used in competing products using .105 thick frictions. Friction formula developed from extensive testing w/ NASCAR Sprint Cup race teams. The increased torque capacity gives the driver a better clutch pedal feel, thereby improving provability. Specs Sold in Quantity Each Hub Solid Input Shaft Spline Count 10 Diameter 7.25 1.125 MFG.

Increased torque capacity provides better clutch pedal feel. 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.

Yes, I recommend this product.
