As power levels move up to and beyond 500 horsepower RAM Powergrip meets the challenge with a combination of organic and metallic disc friction surfaces that effectively increase the clutch capacity to the 550 horsepower level. The 8-spring hub is equipped with RAM Poly-coil 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 percentage more clamp pressure than stock, and meets SFI specifications. At this high level of performance RAM Powergrip provides surprisingly good driving characteristics with smooth, comfortable driver control. Sets include pressure plate, disc, release bearing, and alignment tool unless otherwise noted.
