Little late to the conversation, and it may not change the path you’ve started down, but if others want an example of sliders welded to the Rubicon rock rails, that’s what I had done. A fabricator friend of mine made them for me to replace my nerf bars.

I like the look a lot better, and the slides are much stronger than the nerf bars, but it did raise the height of the step by about 4 inches. With my 35s and a 4" lift, it’s more of a stretch to get in.
