MB4-HDR4 kit features ACT's most popular Heavy Duty pressure plate. 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 rigid race discs are made with high quality, ceramic friction materials. The chrome-moly hub is heat-treated for strength and durability. The lightweight, rigid design allows for quicker shifts and smooth, trouble-free service. With the 4-pad rigid race disc, engagement is harsher, but shifting is faster. The 4-pad rigid race disc is well-suited for the smaller disc sizes in smaller engines.

Features:

  • Light to moderate pedal effort, aggressive engagement, increased gear rattle
  • Moderate friction life, extended by ACT's exclusive diaphragm design, rigid design may increase spline wear
  • Carefully engineered, precisely assembled, accurately balanced, uses select ceramic friction materials for high heat tolerance and maximum performance
  • Recommended for race use only
  • 100% clamp load tested and dynamically computer balanced for smooth high RPM reliability

    Bright color easy to see but not a great bounce on the outdoor court
    Style: 6 - Pack, Color: Pink
    I liked the fact that these balls were a bright color and easy to see but the bounce on them was not as good as other name brands. They were OK as a back-up and performed better outside then on the indoor courts which are made of a different surface. We are using them , but would most likely not repurchase.

    Price was best I found for quantity anywhere
    Style: 6 - Pack, Color: Purple
    I am a beginner and by no means an expert, but these balls appear to be as any other. The couple at the next court had a Franklin ball that came our way, and I bounced it and popped it back - I couldn't tell any difference in that instance. Sports stores had just one color - yellow (maybe one had chartreuse) amazon has single colors multiple - I thought it was worth this purchase. The purple may be harder to see on cloudy days - as I had on sunglasses and I could see it, but the fence at the court has a "privacy" net, it kinda bleneded in for a very brief moment until the sound was heard of the return, then no problem.

    Great Balls!
    Style: 6 - Pack, Color: Purple
    Great Outdoor balls. These are correct weight at 0.85oz and with 40 holes for outdoor play, not indoor as some other reviewers claim.

    NOT Outdoor balls.
    Style: 6 - Pack, Color: White
    NOT outdoor. Don't waste your time if you are looking for proper outdoor balls, these are indoor. I don't play indoor so couldn't use them.
