If it's a 2WD, leave it stock, lower it or make a pre-runner. Just don't think you'll actually go 4 wheeling in it over more than a dirt road, you won't, and making it look like it can, when it can't is just plain stupid.

If it's a 4WD, leave it stock, or lift it, just don't lower it because it serves no purpose unless you are making an ice racing truck.
