      Increased Clearance. You may find upgrading with a lift and larger tires has limited your JK's tire clearances during off road travel. An easy way to prevent that undesirable flare rubbing is to invest in flat style flares!

This kit will help improve approach angles, maximizing off road articulation, all while maintaining a clean look designed to complement your factory finishes.

      Quality Construction. These Flat Fender Flares are crafted from durable thermoplastic with a matte black finish for exceptional styling. Integrated mounts are included to recess your factory side marker lights for maximum clearance. Each flare is UV treated to prevent fading and chalking for long lasting performance no matter where the road or trail takes you.

      Clean Appearance. This kit comes complete with fender liners will help keep mud, dirt and debris off your inner fender paint and help protect your investment by preventing surface damage which could lead to rust. Its perfect for off road and street Wranglers alike, giving both a clean and finished appearance.

      No Drill Installation. This kit includes all the mounting hardware you'll need for installation on your Jeep Wrangler JK or JK Unlimited including side marker brackets for legal on road travel. No drilling or modification to your Jeep is required for a hassle free upgrade.

      Application. The RedRock 4x4 Flat Fender Flare and Flare Liner Kit is designed to fit 2007-2018 Jeep Wrangler JK and JK Unlimited (4 door) models.

        Don't Do It

        I purchased the Fenders and liners. OMG it was bad. First, fitting them was a nightmare. Second, look at the way the side lights are secured in their bracket, it's a joke. I paid $800 for fenders and liners that are mounted with flimsy plastic push rivets, instead of bolts. They are junk. I say "Don't Do IT" you'll be sorry .

        Clean look

        The install was a little more complex than the videos portrayed. I had the liners and fenders installed at 4WHEEL PARTS. They look great. Took professionals 4 1/2 hours to install the items. The Jeep looks great.

        Good looks, poor fit

        The flares and liners look good, but the liners are a terrible fit in the rear. Particularly the left rear. Drilling is required to make them fit. The instructions are also terrible. For example, there's no indication as to whether the flares go over or under the liner (I went under). There's no clarity on how to fasten the bottom of the rear flares, that are too small for the 8mm Christmas tree style fasteners. One surmises that the 6 mm bolts should be used - but there are a couple of locations where it is impossible to use those bolts. For anyone expecting to simply put these in place and secure, I'd go with a different brand. Apparently, this has been an issue for a long time and the manufacturer has never bothered to fix it.

        They look great!

        It seems like the Red Rock kit is made by rugged Ridge as I recieved instructions for both in the box. I love the clearance and the way they look. I did have to go to the local auto parts store and purchase some additional fasteners. Install was a little bit of a nightmare getting things to match up right. But once they’re on they look amazing…

        Great product, bad directions

        Love the fenders, directions not so much! Once we figured out the wheel liners went on top of the fender flare holes, it was a breeze to install but it took a good two hours of wasted time to get to that point. Gives a nice aggressive, raised look to the jeep while keeping the stock design since the flat flares curve down in the front. Quick shipping from Extreme Terrain!

        Poor Fit

        Fit is terrible, instructions are a poorly printed PDF file. So poorly printed had no idea what the pictures were. I needed the rear because of rubbing, when it cools off and I have an entire day I will attempt the fronts. Holes not where they were supposed to be, sizes were wrong. Says no drilling but if you want them to stay on plan on drilling and using your own screws.

        Don't buy. Poor fit/make.

        They look great, at least what I can tell from the 1 that was able to actually go on. I couldn't even get the back two on because It didn't fit right, needed drilling or to be heated because the plastic was warped. So disappointed in the manufacturing of this because I was so excited to get these and I'm left fuming by how poorly made they are. The fenders and liners come seperate, would make sense to have them made together to ensure they fit, it doesnt take a genius to figure that out. Front fenders are very flimsy. Instructions are no help either. Didn't test drive them since I didn't get them all on before I set up my return. When removing stock fenders and liners you will break many of the plastic pieces that hold them on, so beware you won't be able to properly reinstall them if you make the mistake of buying these. Until I order and receive new ones, I'll be rolling without any fenders/liners/side markers. Don't buy!!

      I would like to upgrade my factory fender flares in the near future. Around October. So as of September 2018, have the fitment issues been solved? There are many many reviews claiming the outside fender does not line up correctly.....

      • We can indeed confirm fitment for 07-18 JK's and JK Unlimited 4 door models.

      Have they fixed the issue with the fitment on the inner fender liners? It seems everywhere you look online, and here, there are complaints about the holes not lining up.

      • We have not received any reports of fitment issues with our most recent batches of the RedRock 4x4 Flat Fender Flares and Liners. RedRock 4x4 has made several updates to this product in the past several months.

      Will the stock inner liner fit with these/

      • The RedRock 4x4 Flat Fender Flares w/ Fender Liner Kit include new fender liners. We have not tested these with the stock fender inner liners, but modification would be necessary.
