HD-M/Race ACT (SB9-HDR4) 4-Pad Pressure Plate Kit
This 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.
All diaphragms undergo a four-stage heat-treating process for unparalleled performance.
ACT pressure plates have precision cover stampings that 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.
With the engagement of the 4-pad rigid race disc being harsher, shifting is faster.
The 4-pad rigid race disc is well-suited for smaller disc sizes in smaller engines.
Monoloc serves as a one-piece direct replacement or upgrade to the standard two-piece wedge collar and wire ring found in pull-type clutches.
The segmented retaining ring's spring tension is carefully calculated and tested for optimal performance.
It provides uniform loading on the bearing and pressure plate to assure proper alignment, regardless of driver influence or vehicle modifications.
Monoloc's construction from hardened chrome-moly steel will provide years of service.
