Re: 5.5 inch lift
i lifted my truck 5.5 inches and put 32's under it. i added a cold air intake and a cat back exhaust and it still feels sluggish. I have the 4L so i highly recommend regearing if your lifting it that high. Look into how much it'll cost you to regear before you lift also. theres always things that add up once its all said and done. My ball joints are gone right now....
6" RCD suspension lift
Gibson Extreme Duel exhaust / way too quiet
