Description: The PO3-HDSD kit features ACT's popular Heavy Duty pressure plate. It utilizes an exclusive diaphragm design to increase clamp load, reduce deflection, and maximize clutch life. The pressure plate undergoes a four-stage heat-treating process for top-notch performance. Precision cover stampings ensure rigidity and consistency. The performance street rigid-hub discs are constructed with premium organic materials containing high copper content for improved heat transfer. Steel-backed lining enhances burst strength and durability. The chrome-moly hub is heat-treated for added strength and durability. Rivet design and materials are carefully chosen for maximum strength. These discs are designed to be the minimum weight street disc for faster shifts. ACT's street rigid-hub discs offer race-proven performance with street manageability.

AS GOOD AS ANY OTHER, WORKS GREAT
Size: 36 sqft, Size: 36 sqft
Used this in my 17 RAM 1500. This stuff works great, just as good as S...ss brand that is also sold on here. Same thickness and same tackiness. And this stuff sticks like crazy, once its laid down and rolled onto the surface, it is hard to remove, so I am pretty sure it will stay where I installed it. It is great value, one box was enough to do the whole roof of the truck with a little left over for small spots. I think it took a total of 2.5 boxes to do my whole crew cab, roof, floor and back wall and most of the firewall, and I also added a layer of their .25" foam. I do notice a difference in less outside noise, from wind and road. I will be doing my wife car soon, and this is the product I will be using again, I recommend this.

Awesome, inexpensive alternative to name-brands!
Size: 36 sqft
Awesome. Stuck well with alcohol prep and time to let liquid flash-off. Very consistent, piece to piece. Backing peeled easily when desired. Compared to Amazon Basics, the butyl seemed a little thicker (infinitesimally) and stickier, foil was less thick than Amazon Basics. Very good value. Started with my nice car, but after completing project, sound dampened all cars in the immediate family it made such a noticeable difference in sound level and quality of music from soeakers. Recommended!
