Design Engineering Headliner - Jeep Gladiator JT (2020-up) Black

Ok - let’s start with, this is not an inexpensive solution. However - it is super high quality. Comes with foam fillers to build out the channels enough so that the acoustic panels fit nice and (mostly) flat. Easy one person job - but don’t try to install without removing the top - the adhesive is too strong and fit too tight above the cross bar. So far - amazed at the difference in heat buildup (I have to park my Gladiator outside in GA heat) and - especially - cabin noise. So much quieter and a much more “tight” feel in the doors closing. Also - can’t lie I love the “new car smell” they are giving (although I realize that is toxic LOL). Get these now.

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.

Slightly improved road noise. Still loud jeep sounds, but less echo and the ambient road pitch is much lower which is less annoying. Temp seems bit easier to regulate, but to be fair it's been over 100 °f all week so this may work much better than current perception. Value? Less expensive that other highly rated liners so a fair value considering the alternatives. I like the look- it's like stock. I'm a light weight woman and did install myself. Despite being unable to completely remove large hard top the install went well. Steps below for solo install. Check pieces in box against included list. Mine had missing sound strips but manufacturer made right and sent missing pieces via FedEx. This delayed install but was worth it. Remove freedom panels. I did those indoors. For cargo and 2nd row I cleaned top thoroughly w 70% alcohol, then took off all bolts, securely propped the hard top up on roll bar to create a 3 inch gap. Lowered rear seats to create flat even surface and used a new foam dog bed to sit on. Be comfortable as possible so you aren't tempted to rush. Before removing any backing check fit several times and practice setting in place. I found the pieces under roll and sound bar were most difficult but starting at open area and working forward under bar with slow peel of backing towards freedom panel area works. The open gap enter freedom panels go create a space to deal w backing removal. Use care to not stretch foam pieces. Window hack: fit several times until happy and comfortable w positioning. Cut/tear backing by all 4 corners. Start at top corner once the piece is well seated all around window and remove backing at top corner to adhere. Remember do not stretch or pull foam. Slowly peel backing and secure foam at same time while piece is in place. With smaller (cut) peel sections on window pieces this is much easier as you won't have bulked backing to stretch foam while wrestling the backing off. Use a roller to help adhere strips and overlay panels.

These are awesome and easy to install with two people. Just be prepared to stick under soundbar with someone with small hands. We rolled the tape back for the backseat panels as we were sticking it. Would be terrible do to without help. We took the freedom panels off and did them. And did the rear seat panels with the top attached. Immediate difference in sound and temperature.

Put these in about a year ago they do every thing they advertise and more. Quiets the noise level in the truck (gladiator) do not need to go above 6 on the volume of the radio now. Can actually talk to the passengers now ( if I want to). Woul highly recommend.

The good.. Noticeably quieter in the jeep, Can tell it will make a difference with heat. Even the door shuts now make a better thunk sound.. Bad.. The direction are garbage, it was missing a single piece of insulation in the front. The panels don't quite fit right, the adhesive both does and doesn't hold them right. They are grossly over priced. Verdict.. Worth it if you do not want perfection or can at least tolerate less than perfection. Don't pay full price..

I purchased this because it is one of the thickest and cheapest and had concerns due to those two factors. I am pleasantly surprised. It was very simple to install with perfect fitment, adhesion and it works! I am now able to have a conversation without raising my voice and leaning over to hear. We'll now find out if it lasts over time. Overall, for the price I am happy. The company went a little overboard with the safety stickers-there were two that said "2 person lift". It weighed less than 5 lbs.

The product was improperly packaged, and many of the pieces arrived crumbled. This caused the protective paper covering the adhesive to separate, rendering the adhesive unusable. After installation, the pieces began falling off almost immediately and would not remain in their intended locations. The only way they might stay in place would be to use a different adhesive, which could potentially damage my vehicle. Additionally, the noise reduction was nowhere near what was advertised. The improvement was minimal to nonexistent, and I also did not notice the claimed reduction in roof temperature. Overall, the product did not perform as promised and was a disappointing purchase.

best investment ever.

Alles super geklappt

Happy with the product. Easy to install and looks beautiful. Sound dampening is great. My baby crying in the back doesn’t ring my ears as bad.

Excelente producto, vivo en una ciudad donde en verano llega a 45 grados y realmente se siente la diferencia. Un tanto difícil de instalar, hablando de los paneles laterales, pero nada del otro mundo. Recomendado al 100%

I was installing this product and made a complete user error and let the rear panel fold and stick to it self. I reached out to Design Engineering and spoke with Eric and he helped me get another pannell for the rear of my Gladiator. I can not say enough about their customer service. Service after the sale. Rare these days. Also they look great and really helped the road noise. A must buy.
