Review: They do the deed and fit my phev 4xe 2022 - It fits the plug in electric model even if desertcart 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.
Review: 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...)

*by A***R on September 30, 2025*

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.
