Protection -- Start with your tires and ends with clearance
They are the most vulnerable part of any vehicle in any terrain condition. An all-terrain is generally your best solution unless you have the funds to have application-specific tires you can mount. We like the Cooper Zeon LTZ which are soft, offer good clearing and excellent wear life.
Next, look at clearance options. There are not many options available but one we've found which could be a great addition to your vehicle, they are a definitive part of a recovery kit solution! http://www.johnsonrods.com
