Under the rear spring pack should be a 4" factory block that has the bump stop built in. This would be the stock rear height.I recently bought a 2005 F350 Crew Cab 6.0 and love it. The guy said it had a 3" lift on it, but im not so sure.. Im not sure by looking at the suspension if it has one or not. I dont see anything fancy. Can anyone tell me the stock height to the fender well or something, or another way to check? Thanks Eric
For the front, my '06 F350 had a 2.5" leveling spacer that sits on top of the front spring. It is probably black, and looks to be a couple inches tall, and sits atop the spring then to the top of the spring frame mount. F350's from the factory seem to sit 2-3 inches higher in the back to begin with. My 2003 was 4" higher in the back on level ground, measured from the top of the tires to the wheel well.
