A common deterrent to traversing obstacles is the possibility of body damage. A common method of reducing this risk is to equip your vehicle with Rock Sliders. These are typically one or two "rails" that run alongside and parallel to the rocker panels of the vehicle. They are attached to the frame and are constructed to allow the full weight of the vehicle to rest on them, so you can "slide" across rocks resting on these bars without damaging the body of the vehicle. Another very important use for the Rock Slider is to act as a support for jacking up the vehicle from the side. A Hi-Lift Jack can be mounted on the Sliders and again, they will support the full weight of the vehicle from one side.
