Looks like they did the classic front shackle reversal. Done on 40s as well.
you do get some lift 'cheaply' and the idea is that the front axle is now allowed to move rearward when hitting a bump instead of the front axle wanting to move forwards at a bump, so the theroy is that the axle moving foward is not fighting the truck when at speed
