ACT
ACT, short for Advanced Clutch Technology, is an American clutch maker. Its range here covers the whole clutch assembly: complete kits, clutch discs, pressure plates, flywheels, release bearings and the small parts in between.
The discs show how the range is organised. Street discs come sprung or rigid, and race discs use four-pad or six-pad designs, again sprung or rigid. Pressure plates are listed as Heavy Duty or Xtreme and the XACT flywheels as Streetlite or Prolite, and twin-disc and Mod-Twin kits are listed as well.
The listings favour Japanese cars. Honda leads, followed by Mazda, Ford, Toyota, Nissan, Mitsubishi and Subaru. The Honda Civic and CRX, Mazda RX-7 and Toyota Supra (A80) have especially wide coverage.
Elsewhere in the Transmission & Clutch section, other brands supply shifters and linkages. ACT is the brand for the clutch itself. Discs, pressure plates and flywheels are also sold on their own, so you can replace a single worn part without buying a full kit.

Description
MB018X 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 Xtreme pressure plates increase clamp load by 50 to 120 percent. Xtreme 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.
Feel:
Moderate to heavy pedal effort, confidence during hard shifts, positive engagement
Life:
Available life extended by ACT’s exclusive diaphragm design, dramatic improvement in release mechanism life
Quality:
Carefully engineered for improved durability, precisely assembled, accurately balanced, major improvement in release mechanism
