The exterior of the Suburban gives little indication of the trucks true capabilities. Modifications are minimal, but functional. Up front it sports a garage-fabbed Baja-style bumper/skidplate made from 1¾-inch, 0.120-inch-wall material. It holds a trio of Kragen Auto Parts-sourced 7-inch-diameter HID lights to help illuminate the trail at night. Hidden behind the bumper is a Warn 8,000-pound winch in case Lorenzo gets the Suburban in too deep (Lorenzo was in the midst of finishing the winch install when we photographed the truck and hadn’t installed the fairlead yet). Protecting the lengthy rocker panel real estate is a set of Lorenzo-fabbed rock sliders made from 2-inch by 4-inch, 0.250-inch-wall material. The Suburban rolls on 40x13.50 Goodyear MT/R tires mounted to 17x9 Pro Comp steel wheels.
