blah... there was a guy from Pittsburg on here that used to own a double lifted truck, though on 33's, with the Superlift rear kit AND an AAL. Add a hitch and bam! That'll qualify as a bumper. Hell it holds up WAYYYYYYYYYYYYY better than the tin metal bumper would in a wreck. My truck's a living testiment of that! lol.
Add 3" for the Superlift kit(now at 30"), take away about 1.5" for the aal(now at 28.5"), add 1" for the 2" tire difference, and you're about 29.5" bumper height.
And honestly, Just toss in a set of Belltech 6400 shackles instead of removing the AAL and installing a new block ontop of your stock block. That's my setup and the truck sits dead level. Superlift gives you a 3" block to stack with your stock block....ewwwwwwwwww. I got that 3" by installing Belltech 6400 2" chevy drop shackles and a Procomp Short AAL and leaving my stock 2.5" block in there.
