I have n 89 bought it lifted, switched out old superlift shocks with skyjackers.... Rides great but I believe the 4" blocks in the rear are causing it to sway more then I would like it to and don't seem to sound for my truck.... It also has a 5" bodylift with 35 12.50 15's did have 20*14's but they're a waste they do nothing but cause damage n a shit ride... But the question is can I do a shackle flip with stock shackles in stock mount holes or even drop them a bit to get the 4" s I need? Any help would be great..
