Which option should I choose?
The table below uses the rating/specification supplied for each exact ACT SKU where available. We do not copy a torque rating from a different vehicle application.
| Configuration | Application-Specific Ratings & Specs | Driver Guidance |
|---|---|---|
|
Pressure Plate: Heavy Duty | Disc: 6-Pad Race Rigid ACTAA1-HDR6 |
Disc material: Race/puck-style friction disc • Pressure plate: Heavy Duty | Aggressive race engagement, with more modulation than a 4-pad disc. Rigid hub gives direct response with greater drivetrain shock/noise. |
|
Pressure Plate: Heavy Duty | Disc: 4-Pad Race Rigid ACTAA1-HDR4 |
Disc material: Race/puck-style friction disc • Pressure plate: Heavy Duty | Most aggressive puck-style engagement; competition-focused. Rigid hub gives direct response with greater drivetrain shock/noise. |
Configuration Details
Pressure Plate: Heavy Duty | Disc: 6-Pad Race Rigid (ACTAA1-HDR6)
AA1-HDR6 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 6-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 6-pad rigid race disc, engagement is harsher, but shifting is faster. The 6-pad rigid race disc is recommended for larger clutch sizes to absorb more heat. This Part Fits:

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. This Part Fits:
Fitment note: Confirm model year, engine, transmission, flywheel, and related clutch components before ordering.
