If you can find used Rubicon rails ($200-ish), you can get the Ace Sliders ($340) and come out a little cheaper than new Enhanced Rock Rails ($700), but lose some clearance as the Ace sliders mount below the standard rails (that may not matter to your specific needs, though).
The PSC weld on steps look great. I had been planning on getting the ACE rails, but these would be a lot cheaper with shipping to Alaska. Any thoughts on these vs the ACE rails and durability. I would be using them primarily as steps.
Do the rubi rails really hold up well? I haven't done anything to crazy yet but I am curious how they will take a beating
The Rubi rails do very well for rock crawling in that they protect your lower rocker from being bang on the rocks. What they don't do very well is keep rocks aways from your rig as there is no lip on them. Also, no step as previously stated.
If you want solid protection then go either Rock Hard or PSC. One the issues with the ACE is you lose ground clearance. Rock Hard and PSC sliders don't reduce your ground clearance and you get a solid platform on which to step.
