Whomoto.com now has Polaris Ranger XP900 rock sliders. These not only protect your tank and wire bundles but they also stop your lower side panels from getting mangled.
XP900 Rock Sliders

They are made from 3/16 inch, 5052 aluminum, they don’t reduce your clearance like nerf bars do and they can be ordered in several different colors.
Great looking and extremely functional. Pick up a pair and save you and your Ranger from future headaches… and body aches!
