I ran 35s on stock suspension and just moved my front axle forward 1" and to clear my 37s I ran a stock pack of 81 4x4 toyota rear leafs just add a longer shackle to the rear got about 2-3" of lift and had minimal rubb but it all depends on whta the truck is for I wanted mine low and kept it low but still kept up with and even out performed some of the bigger more built rigs
