Description:
The AR1-HDR4 kit features ACT's most popular Heavy Duty pressure plate. ACT Heavy Duty pressure plates use an 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:
- 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
- Recommended Use: Recommended for race use only
- ACT Difference: 100% clamp load tested and dynamically computer balanced for smooth high RPM reliability

Great toy
Color: Hambone Super Chewer, Size: M/L
My dog loves this toy so much. He's not quite so aggressive with his chewing, now that he's getting older, but this toy lasted through his younger years, and recently started to show signs of wear. He was so sad when I threw it out, that I had to replace it. Glad it still exists - we got the first one probably 5 years ago.

Great for heavy chewers
Color: Hambone Super Chewer, Size: M/L
Our dog is a hard core chewer! This toy is very durable. Even the covering has lasted. We assumed we would need to take the cover off right away but it’s still going after 3 months. It’s definitely chew resistant

Great treat dispenser
Color: Hambone Super Chewer, Size: M/L
Great rubber toy, the outside fabric did not last long, so glad that it is a treat holder/dispenser otherwise it would have been done for in about 10min. The opening for the treats is pretty small so can only fight thinner broken up treats. Great for larger dog that likes to dissect her toys, keeping her entertained longer and no fluff all over the house

My dog loves this toy!
Color: Hambone Super Chewer, Size: M/L, Color: Hambone Super Chewer, Size: M/L
My dog LOVES this toy. It is so cute. It was a little smaller than I thought it would be, but it’s actually the perfect size for him. He carries it everywhere with him, and if he happens to have forgotten it, we say “go get your pig” and you can see it click in his head that he forgot it, and he runs to get it. He loves to drop it to make it bounce. He is 9, he used to instantly rip anything to shreds, but he seems to have gotten a little more delicate in his older age and after a few weeks hasn’t gotten through to the harder toy yet. Once this toy bites the dust, we will have to buy him another because of how much he loves his pig.

Not a Good Choice for Chewers
Color: Get Ripped Margrrrita, Size: L
I loved the idea of this toy, but it did not work or last as intended. It is pretty heavy and made of thick rubber. The flaps over the cup where the treats are dispensed did not last 5 minutes with my pup, so we can no longer use it to dispense treats/use as a brain game.
