They do the deed and fit my phev 4xe 2022
It fits the plug in electric model even if Amazon warns you not. I was even ready to use scissors but it actually fits, i dont mind that pieces are a bit bigger than holes. My picky wife and kids actually noticed the extra quietness and coolness, i didn't told them beforehand to get a real feedback, and the roof is not baking us anymore. It is a deafening material and gives that weird sound absorbing feeling. My dislike is that if you fold or wrinkle the front sides, the wrinkles are permanent but nobody is looking up attentive all the time right? Rollers will cause this and you'll get a long line of wrinkles. The center panels are the hardest to put on but i have good skinny fingers and was able to slide them in. These may seem like they dont fit but they do, you might be hitting something or have it backwards, check multiple times u got the right part lol. It is true that removing the whole roof makes it easier but I'm lazy.

Price seems high, but it works great.
I was hesitant to spend this much on some pre-cut foam, but after reading the reviews, I decided it was probably worth it It was! These are precision cut, and fit great. They make a huge difference on the heat radiating from the top, and they help a lot with noise too. Let's be honest, nothing is going to make a Jeep JLU quiet inside like any normal SUV, but these definitely help. (I have a Yukon XL Denali, and the first two times my wife rode in the new Jeep, she asked if all the doors and windows were closed... (They were, LOL)) Do take the top off and set it upside down on a blanket to make installation easy. Test fit each piece before removing the backing paper so you know where to place it for real. Once it is stuck down, it is NOT moving again! (This is reassuring that it will not fall on my head some day...)

Great product, fit perfectly
pretty easy to install. makes a huge difference on noise level and the Jeep stays cooler as well. adhesive is super sticky, be careful not to touch it to a surface you don't want it to stay on.

more comfortable ride
These were super easy to put in and I actually did not have to fully take off the hard top. I was able to notice a decent difference in road noise, granted it is a Jeep and it's going to be loud on the highway but these made it more tolerable. The one thing I was not prepared for was the temperature regulation. They kept it warmer in the cab in the winter and cooler so far in the summer compared to the last year. It makes it easier to warm up and cool down the cab as well. Would recommend.

Amazing Heat reduction
Well over Memorial Day weekend I bought my first long overdue Jeep Wrangler Unlimited with Hardtop as a retirement present! I live in South Florida and driving home from dealership I realized this is going to need some type of inside insulation before summer. I scoured the internet and this company (DEI) kept coming up as the best. So I ordered the kit in a couple days it came. Next day I followed instructions and began installing panels took a little over an hour and half (take your time). Looked incredible and fits well, but the next day would tell it if it works. Well it hit a record 96 degrees I got in and knew it felt a lot cooler than without panels. I turned the AC on and within 10 minutes of driving I could turn it on low whereas before it wouldn’t keep really cool on high! I’m sold costs a little more but money was well spent! Also makes sounds system and conversations sound way better too! Try it your’ll love it!

Great product at a good price.
Great product, fits extremely well, and does provide some sound proofing. I highly suggest removing your top to install. Getting around the speaker bar was very challenging.

Pre cut but not the quality I expected.
These should have at least some cloth for $300. Precut pieces of foam that fit the grooves. A big pain to stick on because they are so flimsy. Should be $40, 60 max. They look OK but they are spongefoam. I saw mats that have cloth or leather style adhesive pieces to match the interior. That could justify the price. Here I feel like I got ripped off.

Big improvement
This really helped quiet the inside of our wrangler. Get the whole set, really helps with wind noise. After we installed these we put some good all terrain tires on, and now our jeep is as quiet as our last suv. Good investment
