Rocker guards are one of the first modifications we recommend for anyone planning to take their Jeep off-road. They are inexpensive protection for an easily damaged and expensive area to repair. We typically look for rocker guards that mount either directly to the frame or solidly to body mounts and the body itself. We wanted maximum clearance nd protection for our project JK, so we opted for Poly Performance high-clearance rockers. They mount rigidly to the body and body mounts and provide a smooth, snag-free, tapered surface for obstacles to easily slide under. You gain the advantages of an expensive custom boatside conversion in a simple, affordable, bolt-on package. Here's how they work.
