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 construction 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. Monoloc is a one-piece, direct replacement or upgrade to the standard, two-piece wedge collar and wire ring featured in pull-type clutches. The spring tension of the segmented retaining ring is carefully calculated and tested for optimal performance. It provides uniform loading on the bearing and pressure plate to assure proper alignment, regardless of driver influence or vehicle modifications. Monoloc's hardened Chrome-moly steel construction will provide years of service.\u003c\/p\u003e\n\u003ch4\u003eFeel:\u003c\/h4\u003e\n\u003cp\u003eLight to moderate pedal effort, aggressive engagement, OE to mild gear rattle, confidence during hard shifts\u003c\/p\u003e\n\u003ch4\u003eLife:\u003c\/h4\u003e\n\u003cp\u003eModerate friction life, extended by ACT's exclusive diaphragm design, dramatic improvement in release mechanism life\u003c\/p\u003e\n\u003ch4\u003eQuality:\u003c\/h4\u003e\n\u003cp\u003eCarefully engineered, precisely assembled, accurately balanced, uses select ceramic friction materials for high heat tolerance and maximum performance, major improvement in release mechanism\u003c\/p\u003e\n\u003ch4\u003eRecommendation:\u003c\/h4\u003e\n\u003cp\u003eRecommended for high horsepower street or race use\u003c\/p\u003e\n\u003ch4\u003eDifference:\u003c\/h4\u003e\n\u003cp\u003e100% clamp load tested and dynamically computer balanced for smooth high RPM reliability, includes ACT's patented Monoloc\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat's Included in this kit?\u003c\/strong\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e4228218 -
