My wife has an 06 Wrangler and the zippers on the windows would work sometimes and other times not. This is a great replacement. A few years back we went to the dealer to look to replace the upper door and at that time it was expensive. We found these recently as a solution to the window problem and they work great. I was hesitant because I had heard that they are difficult to get on. It took me all of 10 minutes to make the change, and most of that was cutting the old skin off of the frame. 2 things to remember: Lay the new skin in the sun for about an hour so it can warm up, and make sure to unzip the window before you try to put in on the frame. Great product
