3.0 Could be better

They are ok could be better fit , doesn’t cover all the areas needed, had to paint inner areas of the Jeep to make them look better , all in all I would not buy them again

2.0 Horrible fit

Didn’t really want to spend another $250 on these but reusing the stock fenders just wasn’t cutting it in both looks and function. So reluctantly I ordered these figuring the end result be worth in despite the extra expense since I loved how my front ones look. Directions were decent, assembly was a little tedious but not bad, was ready to get them on. The passengers side took a little finagling but went into place, fitment was good and I was happy with the look and excited to get the drivers done. That’s where the excitement ended. The holes would not line up no matter how I tried to reposition the liner. Oh, speaking of holes, there were only 3 drilled in that liner and there should be 4 like there were on the passengers side. I noticed that it would not seat because it was hitting the fuel fill tube and there was no way to maneuver around it because of electrical connections that are also right there. Since I already had the other side on and didn’t really have much of a choice, I wound up having to bend and shape that section in order to make it work which made the paint crack. Not sure if they gave me a drivers side for a JK instead of a JL or what but I’d expect more for what they charge for these things. Aside from that, I’m happy with the look since they match the fronts.

Q: Does the insert come dual color like the pic or all black? Also any comment on the fitment issues from the reviews? Answer this question

A: They’re all black except for the screws/fasteners which are stainless. The only fitment issue that I ran into was I had to bed the rear drivers side liner to get around the fuel fill hose on my JL

Answered by Ron B from Illinois on 08/23/2021

A: It comes all black. I painted mine to color match my Jeeps body color.
