[Ben Williams]

Anybody lifted a 4x4 quadrasteer? Looking for 3". Would a normal suspension lift work or would I just be looking a a body lift?

Power

Looking at options

I have the 6.0L

Head and cam, Turbo or supercharger. I have $6000 to spend.

I want the same gas mileage or better.

As soon as you lift, you are most likely going to loose MPG. If you put more aggressive tires, more loss of MPG. I heard you can gain a tiny bit by installing an electric fan, but i have never seen any actual numbers from testing to prove it makes much of a difference.
