The new Rock Hard 4 x 4 angled up tubular rock sliders are the ultimate rocker guard for anyone looking to do some upgrades. These are an easy installation with precise fitment. Each mounting bar is 2" x 3" .120 thick steel making them some tough rock crushers. These mount to your already existing body bolts with tabs over 3 times the factory width plus through the floor of your JL in existing holes. This means more mounting points for an even stronger, rattle free, and exact fitting rock rail. The Sliders end caps are welded shut to prevent debris, water and dirt from getting in. All hardware is included and instructions.
