almost all vehicles have the rear narrower than the front to cut the turning circle / radius down .


matched front / rear width = 5 acre field to turn around .

rear narrower by just a few inches cuts down the size of the circle = 3 acre field to turn around .

if you dont need to turn tight or just want the looks ad a 1.5" spacer to each side is what most guys have done for years .

if your hard core builder some guys find van axles can be wider over truck axles on some models .

i have a van width 14ff 1 ton rear under a truck and its 70" wheel mount to wheel mount . my dana 60 1ton front is 69" w-w mount so now i am 1/2" narrow on each side in the front . but the look is so much better .
