    I was looking through my RPO codes and came across a 6XL and 7XL. The site I used called it: COMPUTER SEL SUSP (6XL). I have no idea what that means. Anyone?

    Just the springs. I think it refers to the coils springs, it should also have something like left frt, or right frt, attached to the description.

    The computer selects the coils spring based upon the options/features on the truck so that left and right sides sit and ride the same.
