well I put the 56"ers on the rear and moved the rear shackle but my u bolts are not long enough for the 3/4 ton springs. I had this problem when i lifted my 86k20. parts stores dont have u bolts long enough... where can I get them and what length is normally used?. Also what leaf springs can I remove from the 56" for more flex with same lift? I did search but came up with nothing. thanks in advance. For those who care.. Im still looking for cheap rockwell hiding in the weeds around arkansas... but i figure ill set up for the 14ff/d44 and ground hawgs for now. Thanks for all the help I have recieved from the site. It was worth the money.
