The HS1-HDR4 kit features the most popular Heavy Duty pressure plate from ACT.
Heavy Duty pressure plates from ACT use an exclusive diaphragm design to increase clamp load, reduce deflection, and maximize clutch life.
A four-stage heat-treating process is endured by all diaphragms for unparalleled performance.
Precision cover stampings are used in ACT pressure plates to provide rigidity and consistency.
The 4-pad rigid race discs from ACT are made with high quality ceramic friction materials.
The heat-treated chrome-moly hub offers strength and durability.
The lightweight rigid design allows for quicker shifts and smooth, trouble-free service.
Engagement with the 4-pad rigid race disc is harsher, but shifting is faster.
The smaller disc sizes in smaller engines are well-suited for the 4-pad rigid race disc.
