RokBlokz Mud Flap Installation Details for the 2018+ Jeep Wrangler JL

RokBlokz Mud Flap Installation Details for the 2018+ Jeep Wrangler JL

Our Jeep Wrangler mud flaps for the JL have been wildly popular within the Jeep community and we want to thank all of you that have reached out to us so that we could get some feedback on what we have made. We would especially like to thank all of the great members from the many Wrangler Forums online and their passion for the JL generation of the Wrangler.


This project started with our very own Jeep Wrangler JLUR. The Rubicon has it's own unique obstacles with the "Rubi Rail" that comes into the front wheel well area. We created a solution with an optional cut out for Rubicon owners. This allows for the rail to pass through a small portion of the mud flap and give the much needed protection and look that Jeep owners are looking for. We do offer the option to receive a solid mud flap when ordering, specifically for those of you that have a Moab, Sahara or Sport model.  For those who have replaced the rock rails or added aftermarket steps rails, you will want the flap without a hole. Most of those dont extend into the fender like the stock Rubicon rail does. As with the rear mud flaps, the fronts have a quick release function that allows for you to be able to quickly remove your RokBlokz for rock crawling and other adventures.

For the rear mud flaps, we designed a custom bracket system which provides a solid mounting point for the mud flaps that does not take away from the overall look and feel of your Jeep.

After spending a lot of time testing, we found that the best solution is to remove the lower corner of the rear factory wheel well liner. This is held on by 3 OEM screws, and removing it gives you access to the frame where the brackets mount. One cool thing about this mounting solution is that it will work with aftermarket bumpers as long as you have access to the mounting points in the frame.

With aftermarket bumpers the liner and lower corner of the fender would be eliminated. However with the stock bumper you can just leave it out. If you would prefer to re-install the liner it would require a slight modification.

The photos below show how one of our customers modified the corner liner to be able to re-install it.  (2024 models have a slightly different liner piece so this would not be the same for 2024+ Wranglers) This modification is not required and done at your own risk.

Has anyone tried to install this with the Extreme Recon Package? Does that change anything?

Paul Wiemerslage - December 7, 2019

I have a 2018 Jeep Wrangler Rubicon(new body style). My main concerns are rocks chipping paint on the rear door hinges. Would you recommend the XL size. I get a lot of snow/ slush on the rock rails and rear fenders too.??? Am I correct that a kit is 2 flap, both front or both rear? Is the standard color black with red lettering. Thanks!
