The ACT MB018 pressure plate uses ACT's exclusive diaphragm design to increase clamp load, reduce deflection, and maximize clutch life for the Mitsubishi Lancer Evolution. Every diaphragm endures a four-stage heat-treating process, and precision cover stampings keep the plate rigid and consistent. The Heavy Duty diaphragm increases clamp load 20-50% over stock and is recommended for use with a street or race disc. The kit also includes ACT's Monoloc collar, a one-piece direct replacement for the standard two-piece wedge collar and wire ring used in pull-type clutches. Its segmented retaining ring is spring-tension calibrated for uniform loading on the bearing and pressure plate, and its hardened chrome-moly steel construction is built for years of service.

Frequently Asked Questions
What does the ACT MB018 include?
The MB018 is a Heavy Duty pressure plate that ships with ACT's Monoloc collar; it is not a full clutch kit and pairs with a separately purchased disc.
What vehicles does the MB018 fit?
It fits the 2003-2006 Mitsubishi Lancer Evolution (including MR, RS, and SE) and the 2008, 2010-2015 Evolution GSR and 2015 Evolution Final Edition.
Why does the Evo X GSR fitment skip the 2009 model year?
Mitsubishi did not import an Evolution GSR for the 2009 US model year, so ACT's confirmed fitment jumps from 2008 to 2010.
Does the MB018 include a warranty?
Yes, it is backed by ACT's one-year manufacturer warranty.
