AI2-XXR4 kit features a MaXX pressure plate for the serious enthusiast. ACT MaXX 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:

  • Heavy to very heavy pedal effort, aggressive engagement, quickest shifts, 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

    Fit great
    Size: Large, Color: (100) White / White / Halo Gray
    Been a couple of months and they seem to be holding up nicely. Real picky about fit of socks and these fit well. They are very thin but very comfortable.

    Under armor is always a win! Comfortable, no peeling, true to size, no squeezing around the arch of foot & affordable.

    Fit well and stay up
    Size: Large, Color: (299) City Khaki / City Khaki / White
    They're a little thin, so good mainly for warmer months. But they fit very well and I've not experienced any slippage

    Low quality socks.
    Size: Large, Color: (001) Black / Black / Castlerock
    I have been buying Under Armour undergarments for years and have noticed a steady decline in quality. These socks are no different. I purchased another six packs of very similar styled Under Armour socks in 2023 and recently they have started wearing out. Those socks are no longer available for reorder, but these extremely similar socks were so I ordered them. The quality difference is obvious just by looking at and feeling them. They are more of a faded black/brown than the black pictured or the black that the three year old socks still are. The material is completely different and feels lighter. When wearing them they already feel like they are bunching up in my shoes, which the old ones never did. I do not expect these to last even a year and will not buy them again.
