Description: The PO3-HDR4 kit features ACT's popular Heavy Duty pressure plate with 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 superior performance. Precision cover stampings ensure rigidity and consistency. The 4-pad rigid race discs are made with high-quality ceramic friction materials. The chrome-moly hub is heat-treated for added strength and durability. The lightweight, rigid design enables quicker shifts and 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 smaller disc sizes in smaller engines.

Very happy
I recently purchased a set of floating shelves, and I couldn't be happier with my decision! From the moment I opened the box, I was impressed by the quality of the materials. The shelves are sturdy and well-crafted, giving me confidence that they will hold my books and decorative items without any issues. Installation was a breeze! The package came with clear instructions and all the necessary hardware, making the process quick and hassle-free. I was able to mount them in no time, and I appreciated how everything lined up perfectly. As for the aesthetics, these shelves are a game changer for my space! They add a modern touch to my room and provide a stylish way to display my favorite pieces. The sleek design complements my décor beautifully, and I've received so many compliments from friends and family. Overall, these floating shelves exceeded my expectations in every way. They are not only functional but also enhance the look of my home. I highly recommend them to anyone looking for a stylish and easy-to-install shelving solution!

Shelf is sturdy and made of good material, easy to assemble , LED strip could be better
Size: 24 x 6, Color: Black-rgb, Size: 24 x 6, Color: Black-rgb
The shelf is built of solid material and it is very easy to assemble and also install. The LED strip is okay, nothing special and if you don't flick the actual switch on/off of the battery pack your batteries will drain EXTREMELY FAST; the RGB will start flashing making it seem unusable/defective because the controller won't function properly either when in reality it's just dead batteries. I'd probably buy other LED strips that are of higher quality, rechargable and have more features if I were to purchase these again in the future. Pleased with the purchase overall though.

wasting your money
Size: 35 x 7, Color: White-rgb
I’m very disappointed with this purchase. The shelves have a questionable finish - honestly, you can get something cheaper and much better quality at IKEA. But the biggest issue is the lighting. None of the lights work. I put in brand-new batteries and absolutely nothing happens. I wouldn’t recommend wasting your money on this product.

Lights stop working after a few usage
Size: 31 x 7, Color: Black-rgb
I had these shelves for a few months now. The shelves are great and are very easy to install. I also like that they offer different sizing, so depending what you are storing on them. They can fit a lot of items and are sturdy so you don’t have to worry about it falling. The lights were amazing at first and the main reason why I bought this product, but after a few times using them they stopped working completely and no longer connect.
