SB11-HDR4 kit features ACT's most popular Heavy Duty pressure plate. ACT Heavy Duty pressure plates use exclusive diaphragm design to increase clamp load, reduce deflection and maximize clutch life. All diaphragms endure a four-stage, heat-treating process for unparalleled performance. ACT pressure plates have precision cover stampings to provide rigidity and consistency. ACT's 4-pad rigid race discs are made with high quality, ceramic friction materials. The chrome-moly hub is heat-treated for strength and durability. The lightweight, rigid design allows for quicker shifts and smooth, trouble-free service. With the 4-pad rigid race disc, engagement is harsher, but shifting is faster. The 4-pad rigid race disc is well-suited for the smaller disc sizes in smaller engines.
NOTE: Subaru has increased the clutch component sizes. Aftermarket clutches that include a flywheel must have the flywheel installed, as designed by the manufacturer.
The included flywheel must be installed due to a larger clutch components on the OEM clutches.
Application Note: 240mm upgrade. Must use ACT flywheel (included in kit).
