NS4-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

    Subtle smell, works well to pick up dirt!
    Size: 8 Fl Oz (Pack of 2)
    Has a nice, light smell when added to the Eufy C20 water. Smell is short-lasting and very subtle, so no irritation to the animals in the house. Easy to use, a small amount is recommended, and I find it works well. Very good value for long-lasting use. 1 cap/water refill, and the water is much nastier than it was when using just water. Very pleased with this purchase.

    Easy cleaning and pleasant scent.
    Size: 8 Fl Oz (Pack of 2)
    It works very well with the robot vacuum cleaner. It cleans the floor without damaging it, leaves no residue or marks, and leaves a soft, pleasant scent. It lasts a long time and doesn't cause any problems for the device. A very good product; I would definitely buy it again.

    So Worth the Purchase !!!
    Size: 8 Fl Oz (Pack of 2)
    I was a little hesitant to buy this since it’s a bit pricey for a floor-cleaning liquid. Still, I decided to give it a shot because the floor in my new apartment smelled stinky due to the pet urine from the previous tenant. It turned out to be totally worth the investment! The floor gets much cleaner with this product—the dirty water tank ends up way dirtier than usual—and the Eufy mop pads no longer smell bad like they used to without this liquid. Also, just a little goes a long way. I fill the tank to the max with water and add about 15ml of this liquid. The instructions say to dilute 10ml in 2 liters of water, and my tank holds about 2.5 liters. So with one bottle, I can refill the tank around 31 times—which is a lot! Since it needs to be heavily diluted, I don’t notice much of the scent after mopping. I do wish it had a stronger fragrance, but it gets the job done, so I’m very satisfied!

    Works good but doesn’t make the house smell nice
    Size: 8 Fl Oz (Pack of 2)
    This works good in our robot vac/mop however it doesn’t make the house smell good when the house is mopped, just when you put it in the water tank. The floors are clean and that’s all I really care about but would it be nice to smell freshly mopped, yes.

    Size: 8 Fl Oz (Pack of 2)
    I love this products. I wish they have other scent for the different season. Overall, this is worth it. I love my vacuum and this product. My floors are always clean and smells great.
