BM17-HDG4 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 spring-centered race disc features a spring-center to properly damp torsional vibrations for quieter operation and resist failure even 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 4-pad spring-centered race disc, engagement is harsher, but shifting is faster. ACT’s 4-pad spring-centered race disc is well-suited for smaller disc sizes in smaller engines.

The 4400 Series clutch system from McLeod is ideal for truck puller and high horsepower sand drag applications. Recommended for non shifting motorsport applications. This series features a Borg & Beck/Long pressure plate assembly,unique to McLeod that also includes counterweights providing additional high RPM lockup capacity. Steel flywheels are included with these systems along with low coefficient friction sintered iron discs. Due to the pin style drive on the floater plate, these multi disc clutches are not suitable for street applications as they will be very noisy at idle and low RPM.
Kits Include: Steel flywheel, 2 LCF sintered iron discs, floater plate & Borg & Beck Long Pressure plate.
