That might actually not be a problem. My old 80 arms were custom made to be (IIRC) 0.5" longer than stock, in order to properly locate the wheel in the well after lifting. As you know, as you lift the truck, the wheel effectively moves forward due to the angle of the arms (sort of like the axle also moves sideways due to the Panhard rod as you lift). So this may be designed purposely in order to put the tire back where it was pre-lift, in terms of wheelbase at least.
Or it could be mistake, I guess... Let us know what WWOR says.
edit: Also helps keep the diff flange properly lined up with the t-case output flange.
