RAM Clutches Powergrip HD 11 Borg & Beck 1 1/8-10 Clutch Set AMC | Jeep

Powergrip HD is a true street/strip competition clutch that can survive spirited street driving and roaring race weekends. The main difference between the HD and standard Powergrip is disc surface; both HD friction surfaces are sintered iron. Sintered iron provides enough slippage on launch to prevent the violent, uncontrollable engagement characteristics of metallic paddle-type discs.
