These all new CALMINI built formed rocker panel skids for the Samurai are the new standard for off-road rocker protection. These custom formed skids are stronger than individual rocker panels or rocker bars as they protect the entire side, not just underneath as well. Installation is bolt-on with minor drilling required to strengthen the unit. Complete kit comes with two formed rocker skids, spacers, hardware, and installation instructions. Don't trust your rockers to anything else!
