Yes, I personally gave the Boss's engineer the specs, pictures, and the offsets that they needed to change... That change Im sure occured last spring sometime. They couldn't supply me the revised parts in time because of what they called "testing". I had to make my own to be able to plow since I wasn't going to wait around. Lowering it was required as well so I'm glad I did.
I ran my plow setup with the stock springs at max last year. This year I went with the heavier springs and its much nicer now. The front dont drop 3+" when you lift it anymore The plow is HEAVY I wouldnt even want to run stock tires with it myself. When you have it all the way in scoop mode vrs V mode the mounting height comes into play.
