Description:

The HC5-SPR4 kit features a Sport pressure plate, providing a significant upgrade. ACT Sport pressure plates utilize an exclusive diaphragm design to increase clamp load, reduce deflection, and maximize clutch life. Each diaphragm undergoes 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.

Description:

  • Feel: Light to moderate pedal effort, aggressive engagement, increased gear rattle
  • Life: Moderate friction life, extended by ACT's exclusive diaphragm design, rigid design may increase spline wear
  • Quality: Carefully engineered, precisely assembled, accurately balanced, uses select ceramic friction materials for high heat tolerance and maximum performance

A Miracle for dry mouth!!

Slim profile, stays anchored all night (Berry flavor is great!)
Scent Name: Berry, Size: 100 Count, Scent Name: Berry, Size: 100 Count
I rely on these nightly to combat dry mouth, and they deliver exactly what is promised. The adhesion mechanism is impressive—once placed against the gum, the disc stays securely anchored for a full 6–8 hours without shifting, allowing me to sleep without interruption. ​The profile is ideal; the discs are incredibly slim and unobtrusive, so you don't feel like you have a bulky object in your mouth while trying to fall asleep. Despite being so compact, they pack enough moisture to last until morning. The Berry flavor is mild and soothing, making it a perfect bedside companion. Highly recommended.

Excellent product for dry mouth
Scent Name: Berry, Size: 100 Count
If you are having trouble with dry mouth, especially while sleeping, this is definitely the product for you. I have severe dry mouth and have tried multiple things including hard candy (yes, I know not very smart) as well as different biotin products, the mouthwash, the spray and the gel, which all do work, but do not last for very long. These stay in place open the corner of your mouth, last for hours and truly work. I highly recommend it if you are having a dry mouth issue

Works great
Scent Name: Berry, Size: 100 Count
I have to use these for about 1/2 a year. I keep bronchitis and sinusitis from about Oct. to April every since I was a child. When I am suffering with these I can't breath through my nose, epically at night while sleeping and would wake up several times a night with dry mouth so bad ir was literally painful. My mom turned me on to these because she was using the with her CPAP. I sometimes have a bit of difficulty getting them to stay put but overall they are great. I have tried the OG, cinnamon, and berry. The OG have no real taste, but you wake up with a sweet taste in your mouth. I tried the cinnamon because I love cinnamon and didn't listen to the reviews stating how strong the flavor is, big regret, it's like putting two or three fireballs in your mouth, won't be making that mistake again. The berry ones are actually best in my opinion. They have a light berry flavor that isn't overpowering, isn't quite as sweet as the OG. Whichever one you choose you won't wake up in pain. I do suggest using only one at first as opposed to the two they recommend, unless you like waking up with your head on a water logged pillow. One generally gets me through the night unless my congestion is super bad, then I will sometimes have to use a 2nd one about 1/2 way through my night when I wake up for the bathroom and realize it's already completely dissolved.
