Had a short bed crew cab 2012 F350 with the 4" blocks in the rear. Just picked up a new 2016 F250 (also short bed crew cab) and leveled the front (1.75"). It exaggerated the lower stance of the rear end, so I want to get the bed height the same as I had on the F350. Obviously I need the 4" blocks and new, longer U bolts. Anything else? I have seen mixed statements regarding shocks, etc. Any driveline parts, etc? Thanks in advance.
