Addictive Desert Designs' Jeep Wrangler JL Rock Slider side steps are built with function in mind. The bottom of the step is a smooth plate of 3/16" steel providing your Jeep with protection in the most extreme conditions. Bolting directly to the vehicle's body mounts give the Jeep JL Rock Sliders extra strength over the OEM step while also allowing our step to cover more of your underbody. Each step includes accommodations for additional lighting. Five provided rock light mounts per step are universal and can mount any brand of light. Lights are aimed to allow the driver to brighten important parts of the trail that are otherwise hard to see. As always, these Jeep Wrangler Rock Sliders are fully bolt-on and made in America.
