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!

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.

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.

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...)

Impressed
I really had my doubts about this product but must say I am quite impressed. I installed right before a long road trip , from Central Texas to Atlanta, Ga. My wife and I could actually carry on a conversation in our jlu . Install was quite simple for me although I am probably handier than average.

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

Waste of money.
Very disappointed with the quality and fit of the item. It’s deceiving because the reviews cover all models and it seems that each model jeep has different material/fit. The JL model is soo cheap, wrinkles, doesn’t fit properly and barely does anything.

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.

Following the instructions, I noticed that Rachel (who packed my package with pride) was a bit too proud and forgot to include two insulating foam pieces for the rear of the hardtop. The installed product looks nice and gives the hardtop a more finished look. Music definitely has a bit more boom to it and I can feel a that the jeep stays a little cooler after leaving the jeep out in the sun for a while. For nearly $400 I was expecting a bit more quality wise as someone with a steady hand can reproduce this for a fraction of the cost. Overall I am pleased with the look of the product, but the low score mostly comes from the quality to price and because Rachel had forgotten to pack some pricey foam after proudly packing it all away.

Bon produit, mais 2 languette était manquante dans mon emballage. J'ai quand même installer le produit mais j'aurais aimer avoir toute les pièces vu le prix que sa coute
