Well I cleaned up the Gmc today and decided it was a good chance to see how I measure up with my Dads 02 Superduty with a Fabtech 8. Hes Also sittin on 37's I on the other hand am rollin on 33's. Soon as I get some cash that will change. BTW the measurements from the ground to the cab on the superduty are 28" and the Gmc was 27". So soon and the 35's are on I should be sittin a little taller.
