Driveline innovator releases all-new line of clutch packs with an improved friction formula that increases durability, torque capacity & drivability in asphalt Late Model applications
In the competitive world of circle track racing, aftermarket technology moves in only one direction – forward. The more powerful these engines become, the more durable your driveline components will need to be. Understanding the demand for better driveline components for high horsepower Late Model applications, engineers at Quarter Master® have recently developed a new line of 5.5" Clutch Packs with a significantly improved friction formula.

The Quarter Master® 5.5" Clutch Packs feature a new, highly advanced friction formula developed from rigorous testing and racer feedback in the NASCAR Sprint Cup Series. The increased torque capacity provided by these newly designed frictions gives the driver a better clutch pedal feel, thereby improving drivability. Durability and performance are also improved due to the increased coefficient of friction.
Each clutch pack comes standard in the 5.5" clutch products from Quarter Master® and is available with one, two or three clutch discs. They can also be used in competing products that use .104"-thick frictions. For more information about the Quarter Master® 5.5" Clutch Packs, call us at 1-888-CLUTCH-1 or visit us online at
