I actually only have a 2" leveler on myt truck right now and when I had the 35's on. I was getting 12.5-13.5 mpg's city and 17 hwy. I drive with my foot on the floor most of the time though, I can't stand going slow. The 8" Rize and million other things go on starting Monday though!

 

ok thanks a lot good luck with the add ons. post some pics id be interested in the 8" lift if everything goes swell with yours.
