ACT BM14-HDG6 Heavy Duty/Race Sprung 6-Pad Clutch Kit for BMW 135i, 335i, 535i, and Z4

BM14-HDG6 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, spring-centered race disc features a spring-center to properly damp torsional vibrations and resist failure under harsh conditions. ACT spring retainers utilize wraparound spring windows and thicker retainer stampings to provide spring support, reduce stress concentrations, and increase strength and reliability. With the 6-pad, spring-centered race disc, engagement is harsher, but shifting is faster. The 6-pad, spring-centered disc is recommended for larger clutch sizes to absorb more heat. HD/Race Sprung 6 Pad Light to moderate pedal effort, aggressive engagement, OE to mild gear rattle; Moderate friction life, extended by ACT's exclusive diaphragm design; Carefully engineered, precisely assembled, accurately balanced, uses select ceramic friction materials for high heat tolerance and maximum performance; Recommended for high horsepower street or race use; 100% clamp load tested and dynamically computer balanced for smooth high RPM reliability

• "Excellence in Performance", backed by the best one-year warranty in the industry!

The ACT BM14-HDG6 Heavy Duty/Race Sprung 6-Pad Clutch Kit is engineered for high-horsepower street and race applications requiring increased clamp load, fast shifting, and dependable performance under harsh conditions. The kit combines ACT's Heavy Duty pressure plate with a spring-centered, six-pad race disc that uses select ceramic friction materials for high heat tolerance and aggressive engagement.

ACT's exclusive diaphragm design increases clamp load, reduces deflection, and helps maximize clutch life. Each diaphragm undergoes a four-stage heat-treating process, while precision cover stampings provide rigidity and consistent operation. The spring-centered disc helps damp torsional vibrations and resist failure, while reinforced spring retainers with wraparound windows improve support, reduce stress concentrations, and increase reliability. Engagement is more aggressive than an OE-style clutch, with light to moderate pedal effort, faster shifting, and OE to mild gear rattle.

The ACT BM14-HDG6 is carefully engineered, precisely assembled, accurately balanced, and 100% clamp-load tested. Dynamic computer balancing supports smooth, reliable operation at high engine speeds. The six-pad design is recommended for larger clutch applications because it helps absorb more heat, making this kit suitable for demanding street, drag, road race, and performance driving use. ACT backs its performance clutch products with a one-year warranty.

Fitment: Designed for select BMW applications, including the 2007-2009 BMW 135i, 335i, 335xi, 535i, 535xi, and applicable Z4 models. Verify vehicle year, engine, transmission, and original clutch configuration before ordering.
