I installed the regular Extra long RokBlokz flaps on my 2021 Gladiator love them very easy install and can be taken off with the thumb screws for off road!
Check out RokBlokz.com they have mud flaps that have a hole for rock rails but you don’t have to punch them out if Rick rails are not on the Jeep very easy to install and can be removed with 3 Thumb screws for off road
I ordered the XL long at first but they changed it for me before shipping so I went with the Original long my tires are 34” high I feel the XL would have been too wide very easy to install very functional no more mud and slush on the rear fenders and doors
