ACT MB018 Heavy Duty Clutch Pressure Plate for Mitsubishi Lancer

MB018 is an ACT pressure plate that uses 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 Heavy Duty pressure plates increase clamp load by 20 to 50 percent. ACT's Heavy Duty pressure plates are recommended for use with a street or race disc. 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. Heavy Duty Pressure Plate Light to moderate pedal effort, confidence during hard shifts, positive engagement; Available life extended by ACT's exclusive diaphragm design, dramatic improvement in release mechanism life; Carefully engineered for improved durability, precisely assembled, accurately balanced, major improvement in release mechanism; Recommended for street and race use; 100% clamp load tested and dynamically computer balanced for smooth high RPM reliability, includes ACT's patented Monoloc

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

The ACT MB018 Heavy Duty Clutch Pressure Plate is engineered for Mitsubishi Lancer applications requiring dependable clutch engagement and increased holding power. Its exclusive diaphragm design increases clamp load, reduces deflection, and helps maximize clutch service life while maintaining light to moderate pedal effort. Recommended for street or race use, this pressure plate supports confident shifting and positive engagement under demanding driving conditions.

ACT manufactures the MB018 with precision cover stampings for improved rigidity and consistency. The diaphragm undergoes a four-stage heat-treating process for enhanced durability, while each unit is 100% clamp-load tested and dynamically computer balanced to promote smooth, reliable operation at high engine speeds. The Heavy Duty design increases clamp load by approximately 20 to 50 percent compared with a standard pressure plate.

This ACT pressure plate includes the patented Monoloc system, a one-piece replacement or upgrade for the standard two-piece wedge collar and wire ring used in pull-type clutches. Its carefully calibrated segmented retaining ring provides uniform loading across the bearing and pressure plate, helping maintain alignment regardless of driver input or vehicle modifications. Hardened chrome-moly steel construction supports long-term service and improved release mechanism durability. The ACT MB018 is designed for use with a compatible street or race clutch disc.
