The biggest hindrance to off-roading our Durangos is the front air dam (well, beside the factory Goodyears.) I was afraid I was going to rip it off when I was off-roading last weekend. Fortunatley, it's fairly flexible but still makes a horrid sound.
I took some photos with it removed to illustrate the improved approach angle, not to mention the tougher stance it gives the truck. I ended up putting it back on until I devise a way to support the lower bumper cover, which I'm sure would flap like a flag on the highway. It's paper thin and I think the air dam serves a dual purpose - to improve aerodynamic drag and to provide structual support to the bumper skin. I'm going to replace my air dam with a 1/2 or 3/4" PVC mounted inside the lip to give the bumper cover some support while still offering some degree of flexibility for those times when I scrape the underside anyway.
