Welcome Greg R, congrats on the X! I recommend getting harnesses before anything else. Being you are a first time SXS owner, statistically you are more prone to roll overs. Harnesses will keep you safe, and in the car. Do you have an extra belt yet, and all tools needed for the change, including the jack? Read up on here for what is needed. You blow a belt, you're stuck. I would also recommend Pace Offroad 12mm stud kit, replaces the wimpy 10 mm studs. Ask as many questions as you have.
