Z64-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

    Nice tire sealant.
    Size: 32 oz
    This seems to work very well. I will say that it seems to be pretty important to move the wheel around as soon as you can to distribute the product within the tire. I was held up for a few minutes and the Liqui tube seemed to start to set up in one spot and made the tire out of balance so I had to work quick to get it to distribute to the other parts of the tire. It seems to have worked though and so far the tires are holding air very well. I will be interested to see if it lasts for a long time but so far so good.

    This stuff works!
    Size: 32 oz
    I was sceptical but wanted to avoid replacing 2 rear tires on my zero turn mower. The tires were leaking air and had bad sidewall cracking. I found the use of the product to be easy and quick. I aired up the tires and rode around the yard a few minutes to distribute the product in the tires. It has been 4 days and both tires remain aired up. Previously both tires would already be flat within this timeframe. Excellent results for me!
