I also have the Ace Engineering Rock Sliders. I did a lot of research and they were the only ones to work with factory rock rails at the time. Maybe more have popped up. But as for the Ace I can say they are awesome. If you look just a few posts above your original, I got sideswiped by a hit and run the other night. The step saved from any damage. I had to scrub some of his paint off. I was doing about 35 at the the and he hit me pretty hard. Heard metal crunching and glass breaking. I thought it was mine but it was his.In 1994 I bought my first Jeep, a Cherokee Sport XJ and then in 2002 a Liberty Limited. Always wanted a Wrangler so after 19 years it was hard to give up the Liberty (lots of memories) but it was time. And 2 weeks ago we picked up our 2021 Jeep Wrangler JLU Willys. Really can't get over the difference in ride, comfort and technology. Who would think this of a Jeep!
All Willys JLUs came standard with the Rubicon rock rails but I'd like to also install nerf bar steps to protect the doors from dents and make it easier for my 5'2" better half easier access in and out. My question is are there any vendors who make them and able to mount them without having to remove the standard rock rails?
