Odd. From the blueOx website "
4. Level the trailer and then measure the coupler height. Install the hitch head onto the receiver
shank, using the 3/4”-10 bolts, 3/4” lock washers and 3/4”-10 hex nuts. Measure the hitch head
ball height. The ball height needs to be the same or 1” higher than the trailer coupler height,
adjust as necessary. Torque the 3/4”-10 bolts to 257 ft/lbs.
Note: Ram Truck owners please reference the Trailer Towing section of your vehicle owner’s
manual for proper hitch set-up instructions. Also, it is recommended for optimal towing
performance to set the ball height 2” higher than the top the trailer coupler."

I'm guessing you either have a Dodge ram or bkueOx needs to standardize their instructions.
