        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.

            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.

            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!

            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.

            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.

            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.

            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

            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.

            Looks awesome

            Great product if your handy. I painted mine to match my jeep. However if you purchase make sure you buy the inner fenders to go along with it. They told me I could use my factory ones you can't. If you try they look horrible well worth the money. I like these because not many have them on the road and everywhere I go people love them.

            I like the looks of the liner and would have rated them higher however, some holes did not line up well.

            Fender liner install

            Works well, would have been easier if the previous owner would have installed the fenders properly. Still looks great with the lights installed.

            RedRock Inner Fender Liner Kit

            These were a great purchase. I did not like the look of the Jeep with no liners. After I took off the OEM gear that was on my Jeep, it did not look good at all. These make it look clean and sharp! I would definitely recommend these to anyone!

            Dont quite line up right

            The liners didn't really seem to be made for the model I bought them for. I installed on 2016 Wrangler Sahara Unlimited. I had to drill out some holes that were too small, and about 70 of the other holes lined up. Im not sure if the liners i reveived had a manufacturing defect but they took quite a bit of work to get on.

            I wanted flat fenders on the wife's JKU from day 1 but she wasn't a fan of the exposed look it created. I wanted the travel and better clearance. These let me get the function while still keeping the look. Brilliant. I you do the install with the fender flares it isn't much extra work.
