The HC9-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 present 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.
Quicker shifts and smooth, trouble-free service are allowed by the lightweight, rigid design.
Engagement is harsher with the 4-pad rigid race disc, but shifting is faster.
The smaller disc sizes in smaller engines are well-suited for the 4-pad rigid race disc.
Parts included are: 4214004, H028, RB820.
