ACT Heavy Duty Performance Street Sprung Clutch Kit for 1983-1991 Mazda RX-7 (ZX2-HDSS)

Fits 1983-1991 Mazda RX-7 models, including Base, GS, GSL, GSL-SE, GTU, GTUs, GXL, LX, and SE trims.

The ACT ZX2-HDSS kit combines a Heavy Duty pressure plate with a Performance Street sprung disc, offering a significant upgrade over the factory clutch for spirited driving and street performance. The Heavy Duty pressure plate utilizes an exclusive diaphragm design that undergoes a four-stage heat-treating process to increase clamp load, reduce pedal deflection, and maximize service life. Precision-stamped covers provide the rigidity needed for consistent engagement under load.

The Performance Street disc is engineered for durability and thermal management, featuring premium organic friction materials with high copper content for superior heat transfer. Steel-backed linings increase burst strength, while a reduced marcel design allows for faster shift action. The sprung-hub center helps dampen drivetrain vibrations for a more refined driving experience compared to unsprung alternatives.
