The ACT ZX6-HDSS Heavy Duty Performance Street Sprung Clutch Kit pairs ACT's most popular Heavy Duty pressure plate with ACT's most popular street disc for the third-generation Mazda RX-7. The Heavy Duty pressure plate uses an exclusive diaphragm design to increase clamp load and reduce deflection, with every diaphragm undergoing ACT's four-stage heat-treating process and precision cover stampings for rigidity and consistency. The Performance Street disc uses premium organic friction material with high copper content for improved heat transfer and a steel-backed lining for greater burst strength and durability, with reduced marcel for faster shift action alongside the Heavy Duty pressure plate. The kit also includes ACT's Monoloc, a one-piece direct replacement for the standard two-piece wedge collar and wire ring used in pull-type clutches; its hardened chrome-moly construction and carefully calculated spring tension provide uniform loading on the bearing and pressure plate for consistent alignment regardless of driver input or vehicle modifications.
