I have a set of the Smittybilts ... no good for rockcrawlin, as they are thiiiiiiiiiin wall ... but they did well to get my wife in-n-out (she's very short.)
'Course, now we're not married I can yank them and put something thicker on... but I digress.
They were a b!tch to install, though, had to drill into the spring hangers and all kinds of weird crap. I'm not really happy with them, and I'm only keeping them to climb over my half doors until I go full cage and real rocker protection.
