Design Engineering 050178 Boom Mat Black Complete Sound Deadening Kit Compatible with 4-Door Jeep Wrangler JL (2018-up)

First of all, when I tried to buy this, the message "This Does not fit your Gladiator" popped up. No idea why it said that, and I nearly didn't buy it, but it DOES fit my JT. Perfectly. This is an Amazon glitch, so they need to fix that.This liner looked great in the box, and it looks great installed. It is highly recommended that the top be taken off to put this on, but I did not take it off. As a result, I have a couple of small errors, but no one will ever notice them but me. It was difficult doing, and it required considerable strong words, but I hate taking the top off. If I had to do it again, I probably would take it off, just because I like perfection.It fits great, and it looks great. I got the white, and it's hardly noticeable. A couple of the backer foam strips were a bit to long, but I just trimmed them off.I just finished the project, and haven't driven it yet, but I anticipate a much reduced sound level. I applied it in the sun (and my top is black) and I could tell a huge difference in the heat coming through as I did each panel. That alone is worth the price.This adhesive is fantastic. It's instant adhesion, so don't let it fold back on itself. Buy this liner! You won't regret it.

OK, wasnt really sure what to really expect with this. Reviews were mixed. The installation is pretty simple. I did take the rear top off my Gladiator but I just rolled it into my bed cover and applied the BoomMat where directed that way. Made that part of the job really easy and it was the first time I had removed that part of the top since buying it a year ago.The install is easy overall and if anyone is unsure if this stuff actually reduces outside noise, take your Jeep through a touch-less carwash before and then after. You will definitely be able to tell the difference.I think it works great! Had one middle piece that wasnt quite cut right but a similar section of the front toos isnt even done in the instructions, so I just didn't put that one in the rear top either.All in all, happy. For this price, its worth it. We’ll see how it holds up to the weather impacts this summer.

2021 4XE. Says it doesn't fit.. but it does. A little annoyed at the instal... the whole backside is sticky so it's troublesome sometimes to fit perfectly..but man it knocks out the sound well.

The product came with no wrinkles, in pristine condition. Installation instructions were a breeze, and the whole process took less than an hour (with taking the whole roof off.) Road noise level is definitely down, and it's easier to listen to tunes and talk to each other in the cabin.Make sure to properly stick it, otherwise it gets the wrinkly effect, which some end users captured. Not over stretching it or pushing it into the corners will get you the perfect result. Killmat IMHO is an overkill, since this set comes with the foam strips already, and there's plenty of buffer.Some folks said you don't have to take the roof off, but with 8 bolts, just take it off and do it right instead of trying to work around the speakers (unless you have baby hands).

Even if you are a little OCD, you will not like this kit. I got the full kit including the side window frames, I wish I hadn’t. The cuts are off just a little here and there which was my first concern. Second was their warning of “don’t stretch the material” when applying. The problem is, at least with my kit, sometimes the material wouldn’t come apart from the adhesive backing. Because of the extra strength needed, it would get stretched. The shape would change just a tad and that lead to wrinkles in the material I would have to try and reshape. I will say this, their adhesive is top notch. If it wasn’t, I would have pulled it off, reapply the backing and returned. The adhesive is so good, after just a short time if you would try to remove the material it tears and falls apart, the reason I feel struck with this product. It does block heat and sound on the areas it covers. All areas that remains white, still hot to the touch in the Florida sun and radiating heat. For this reason as well as wanting a more professional/factory installed look, I wish I would have spent a little more and went with the full interior roof package another company offers. LEARN FROM MY MISTAKE. Since you have to take the roof off for this install, go with the other better product that requires roof removal as well.

I put mine up w/o fully removing the topper, but was able to do it. What a difference after installing though! My jeep heats up and cools down faster, the highway noise is way down, it's just crazy how much of a difference it is. I did also use some 3m adhesive spray to help make sure they stick, but I prefer to have some overkill than to have to deal with it later.Really recommend these as a small little weekend project for upgrading your jeep.

First off I used a Killmat 80 mil first layer to eliminate vibration/reverberation of the roof panel sections which alone makes a huge difference. That being said, it doesn't do everything and its the combo of these two products that really make an eye-popping difference. The thick multi-layer foam in this kit levels everything out and I heard a huge difference in my Jeep Gladiator as soon as I started driving. I was going over bumps and rough roads that normally I would hear flexing/creaking/vibes from the roof panels. That was all gone. In addition the multiple layers of foam on top help eliminate echo's inside and although not a lexus, my whole family noticed the quiet sound and ease of conversation on the highway. The feel/appearance looks great to me and will even out quickly. Pictures are right after everything was installed at each step, but even if the don't I like the look and feel. LOVE the sound difference. Easy install, although I removed the whole top to do pre-wipes with IPA and a microfiber cloth. As others have mentioned this product has a VERY strong adhesive that if you somehow managed to get stuck to itself will be very difficult to unstick if not impossible. I was careful and didn't have any close calls.
