The Ultimate Kit came with everything required to complete the installation. Missing a few instructions on the supplied instructions, but many online videos available so went well. deviated in a few spots from instructions for what seemed a better solution. Happy with product and delivery was on time.

A bit finicky to install on GM MultiFlex tailgates because there are so many different areas to be sealed but there's no way around that. It cuts easily, the adhesive allows you to reposition it a couple of times while still adhering well once you do. The instructions are good, although I did end up modifying their suggested installation orientation a bit and had to add a second piece of seal in one place beside the recommended section to get a final seal. They give you plenty of extra seal. My one frustration is one we have with everything that comes with adhesive that has a plastic strip protecting it that you have to peal off. Starting to peal that protective plastic off can be annoyingly difficult at times. Not a reason to mark this product down...just something to be aware of. In the end, this worked. My truck bed is basically pristine after driving on a dusty road and gravel driveways.

Package came perfect condition until you open the box, sealed bag containing item was torn open, all peices were intact and in good shape, the installation was a chore, the instructions were hard to follow, but persistence prevailed , got job done, seams to do the job, we will see

I WAITED A AWILE to review this seal kit. put it on my 2025 chevy 2500 hd with the multi flex tall gate. what a dust leaker that is with a camper shell i could fill up the back end with a lot of dust! Well i don't have that problem anymore. Did it stop all the dust no but it did stop most of it very little get in there now. make sure you clean all surfacer before installing. Work great!!!!!!!!!!!!

this product comes with everything you need to install. Came with a bunch of alcohol wipes. when all is said and done, I’m sure it will help the problem that I find is some of the locations where this is adhered to will eventually fall off, just based off a use. There was leftover so if this happens, you can replace.
