OLD318 -- if the tires aren't hitting the inside rear frame rails upon full lock, then it sounds to me as thought the Borgenson box actually increases the turning radius... not desirable.. as I prefer to have a tighter (smaller) radius.

On the factory T/A Fast Raitio boxes, there are internal "stops" which limit the turning radius due to the known physical fact that the tires would hit the rear frame rails.
