I got an f250 with a full float 60. Because the shafts are not designed to carry weight, they are smaller and have less splines than the semi-float model. Also, most come with huge heavy drums that are no fun to mess around with. The full float isnÆt worth it, since the jeep will not be seeing the weights required for a full float. It will be seeing LOTS of tourq, so the added splines and shaft diameter are nice.
