These are some of the beefiest rock sliders on the market. Built entirely from 3/16" steel they are designed to take a beating, and protect your Bronco from whatever you can throw at it. These were designed with protection and function in mind. The angled "boatside" design helps to slide off rocks, and the rail protrudes out from the side enough to keep your door off the rocks alongside. They also have the added benefit of deflecting any rocks those big mud terrains like to throw up at your paint. Slots are also cut in the lower section to allow a solid engagement point for using a hi-lift jack on the trail.
