Mud is easy. Youll need a D60 front something big in the rear, lockers front and rear, and at least 400hp. Next put on the biggest tires you can bear to drive on with the most aggresive tread(usually boggers) and your done. Other stuff i reccomend are 35spline stub shafts for the 60, gears to go with the big tires, 500+ hp would be better, and good bumpers/ tow points front and rear.
