The best clutch for you will be determined by your application and your budget. Of course the lighter clutch you can get away with, the easier the engine will accelerate. An 8.48 lb. 2 disc 7.25" clutch is tough enough to withstand almost any short track racing application. An 10.99 lb. 7.25" 3 disc will last longer, but is only really needed in extreme traction and power applications or road racing. The 7.24 lb. 5.5" 3 disc clutch will handle the same applications as the larger 2 disc but with less total weight and a smaller rotating diameter. We recommend using the 5.66 lb. 4.5" 3 disc clutch in applications with 500 h.p. or less. 4.5" clutches may not be the best choice for weekly racing.

The Quarter Master Pro-Series clutches are known for their years of reliable performance and service. These clutches are driven by the outer housing or "ring". They are available in 4.5", 5.5", and 7.25" styles.

The Quarter Master V-Drive clutch offers several benefits. The open design offers lower inertia, dust escape, and improved cooling. The one piece billet aluminum cover is over 20% stiffer than the competition. The V-drive uses spline engineering formulas to give the clutch precise balance and to evenly distribute the thrust forces .
