I want to install some side steps - I am tiny. I have the Aries rockrail/steps on my TJ and love it. Thinking about doing the same with the 4xe but it appears that it came with some kind of rock rails already - do I need to remove those? Are there any steps that attach to that or do they need to be replaced? I like the Aries rails/steps because they are trail-friendly. Do you think I could sell those rails that came with it? Thanks for any input.
