As power levels move up to and beyond 500 horsepower. A direct replacement RAM powergrip Clutch will meet the challenge with a combination of organic metallic disc friction surfaces that effectively increase the clutch capacity to the 550 horsepower level. The 8-spring hub is equipped with RAM polycoil damper springs encapsulated in polyurethane. This spring can handle three times the shock load of just the coil spring, and is standard in all RAM competition discs. The Ram competition pressure plate in this kit provides 30% more clamp pressure than stock, and meets SFI specifications. At this high level of performance RAM Powergrip provides suprisingly good driving characteristics with smooth, comfortable driver control. Sets include pressure plate, disc, throw out release bearing, and alignment tool unless otherwise noted.
