Do the suspension lift. A body lift just helps larger tires clear the fender wells. A suspension lift actually cranks up the chassis as well, giving your engine and transmission (well, all the goodies pinned to the underside of the rig) more clearance. That is much better for your off-road driving....not slapping skids on everything. After that's done (or even at the same time, but not before) is when you want to put the larger tires on. Also, a body lift changes the geometry of the truck more than a suspension lift. So, get the suspension instead!! I highly recommend Demello Offroad for your suspension needs.....or we can do an install day, and have a few folks get together and install stuff.
