    Well, I'm in the process of putting together some money for a 4" lift and tires and was just wondering about a 14bFF. I told my sister's bf about it and he said that you would probably have to change the master brake cylinder if you swapped the 1 ton axle in there because of the bigger brakes. I was just going to ask you guys what you thought about this idea. Did any of you guys have to do this? What is all involved? /forums/images/graemlins/1zhelp.gif

    no need to swap the master cyl.it takes very little fluid to move the wheel cylinders.get one from a 73-87 3/4 ton,and it will bolt right in.i think with a one-ton rear,you will have to move the spring pads,i think.you will also need a conversion u-joint,and 8 lug wheels.shocks will bolt up,as will brake line.very easy swap.

    one ton dually van?,if thats like a dually p/u rear,it will be narrower than a single rear wheel axle by a few inches.spring pads will still need to be moved.

    The van width 14's will actually make the back tires stick out farther by about 2 inches on both sides than the front axle. As for the spring perches, they will have to be moved inward towards the differential. As to how much, I dont know.
