Ok a few questions. My 2011 f250 super duty diesel still has original shocks and suspension on it. Will the old shocks cause the front of the truck to only sit a .25 of an inch lower then rear. I'm trying to figure out if I can get 295/75R18 tires on factory rims to fit. Or if I'm going to have to change the shocks, and/or lift the complete truck two inches. I don't want to cut the plastic out of the wheel wells or have them rubbing.

 

You would be able to fit a 295/65/R18 on your factory wheels with no issues. That would be about 1/2 an inch wider and about 1 inch taller than your stock size.
