Rocky Road Rockrails are the creme' de la creme' of the Jeep rocker protection phenomenom. We use 1/4" inner hitch steel to make sure your bars do NOT bend! Anything else is just plain flimsy. Most other rocker bars are made from thin 1/8" wall material and a good number of the Rockrails we sell are to those who have bought these thinner bars and have bent them up. Even slick looking dual tube designs that appear to offer better protection are still only made from 1/8" steel and will bend on a hard impact. As pretty as those dual tube jobbers may look, when push comes to shove, and rocks come to crunch, those dual tubers will bend.... and many times, they'll shove themselves up into the body causing vehicle damage when they do collapse. We know, we've replaced many of them for customers as well. At 1/4" thick, ours are the absolute strongest rocker protection you can buy in the universe.
