For those looking to enhance their performance ride, the ACT MB4-HDG4 Heavy Duty 4 Pad Clutch Kit is engineered to deliver the robust engagement and reliability you crave. This kit features ACT's renowned Heavy Duty pressure plate, designed with a unique diaphragm that boosts clamp load while minimizing deflection. This means you get a clutch that not only lasts longer but also performs at its peak under pressure.
The MB4-HDG4 is built for enthusiasts who demand more from their vehicles. The pressure plate undergoes a meticulous four-stage heat-treating process, ensuring exceptional performance and durability. Its precision cover stampings provide the rigidity necessary for consistent operation, even in the most demanding conditions.
What sets this kit apart is the 4-pad spring-centered race disc. This design effectively dampens torsional vibrations, resulting in a quieter operation while maintaining strength against harsh driving scenarios. While engagement can feel harsher, the payoff is faster shifting—ideal for both spirited street driving and track days.
The ACT MB4-HDG4 is compatible with a range of vehicles, making it a versatile choice for many enthusiasts:
Owners of the Mitsubishi Eclipse (1990-1994) have noted, “Installing the ACT MB4-HDG4 on my Eclipse transformed the way it drives. The shifts are so much quicker, and I can really feel the power transfer without any slippage.” Another Mitsubishi Mirage (1991-2002) driver mentioned, “This clutch kit is a game changer for my daily driver—smooth engagement and no issues with torque under load.”
