JP2-HDR6 kit features ACT's highly regarded Heavy Duty pressure plate and rigid 6 pad race disc delivering high torque capacity, aggressive engagement and increased toughness to withstand the demands of off-road racing. ACT’s exclusive diaphragm design increases clamp load, reduces deflection and maximizes clutch life. All diaphragms endure a four-stage heat-treating process for unparalleled performance. ACT precision pressure plate cover stampings provide rigidity and consistency while precision machined pressure plate castings absorb heat. ACT’s rigid center 6 pad race discs have a virtually indestructible rigid center and premium ceramic friction materials to hold power even under the most abusive conditions. Rigid design eliminates torsional damping for simplicity, reduced weight and quicker shifting.
