        Alright for what they are.

        Decent liners. The only drawback is that the holes don't match up 100

        Be Careful!!

        The kit itself was fairly easy to install. It did NOT come with instructions! After figuring it out. Not too bad. I had to do a bit of drilling to make it fit right.

        2 2018 Rubicon - EricF Installation Time: Afternoon

        Disapointing

        The design on the light mount is cheep at best, I bought the inner liners as well so I got 4 clips, 2 broke, the 2 that worked wont last. You do break clips removing the factory fenders, so relying on the fit of the new ones is paramount, my rear inner liners didn't come close to fitting the front had to be modified, defiantly not worth over 600.00 bucks. Overall very disappointing!

        3 2008 Wrangler - MartinL Installation Time: Afternoon

        A Few Issues

        Got the liners and fenders. As mentioned by others, rear liners did not fit well and drilling was required. Front liners and fenders were each missing a hole and require drilling. Front liners are not like in photos and instructions. Mount for side running lights is missing. Luckily there is a mount with the fenders. The missing mont (hole shown in photos and video) for the liners required a return and the same configuration was sent the second time. Only three fender flares were delivered the first time requiring another return. Recommend an additional hole and bolt be added at frontmost position on front fender flares.

        5 2008 Wrangler - Burroman Installation Time: Afternoon

        Easy to install

        There are probably heavier duty fenders but I like the fact they flex. I’m hard on my Jeep and like the bend when absolutely necessary.

        3 2008 Rubicon - DeanC Installation Time: Afternoon

        Liners don't fit as well as the fender flares

        I ordered both the liners and the fender flares at the same time. Although the flares pretty much matched perfectly, I had a heck of a time getting the liners to fit - especially on the rear of the Jeep. The holes did not line up - some were off as much as 3/8 inch, and I ended up trimming excess material from the edge of the liners to get them to fit into the well properly. I really do like the looks, but the installation didn't go well until I reamed out some of the mounting holes and got the excess material trimmed off.

        1 2016 Wrangler - Lukas1015

        Unsatisfactory

        I was looking forward to having actual fender liners on my 2016 JKU. Liners were very badly trimmed and holes didn’t aligned at all. Worst part is I call to send them back to Extreme Terrain I have to pay $150 for shipping.

        Clean look less noise

        I run a fairly aggressive Tire and going with the plastic inner panels and not the steel inner panels was one of my better moves the rocks hitting the inner panels driving on dirt and gravel roads are not near as noisy no rattles from the steel panels

        3 2014 Wrangler - PeterStassi Installation Time: Afternoon

        Not bad

        They look good but installation was a bit tricky because the rear liners didn't line up nicely with all the pre drilled holes where they belong. Had to muscle it in. Directions are vague but you can figure it out.

      Will these cover the gap from a 1 inch body lift?

      • They would not cover the gap from a 1 inch body lift since these are meant to also fit a Wrangler without a body lift.
