To protect the rocker panels of the Jeep we chose a set of rock sliders from Poly Performance. Made of 3/16-inch plate, these pieces of armor are designed to fit tightly against the body for more clearance. They mount by incorporating both tub-side mounts and using all the center body mounts for lower mounting points. At first we were apprehensive of drilling 10 holes in the side of the tub for mounting, but after a week off road we wouldn't trade these sliders for anything. We had situations where we drove the Jeep off a rock and dropped hard onto these sliders and they didn't even dent, and that is with a Jeep that weighs twice what a stock JK weighs.
