So I have a 99 f250ld that i want to put a lift kit on. Will a f150 lift kit work on a f250ld? I want to do a RCX 2.5" lift which would use tortion keys in the front and axel blocks in the back. I hear that this will ruin the ride. If I go with 2" longer shocks will this fix the ruined ride? Also i have factory air bags in the rear and one is leaking. Apperantly they are $500 a pop new from ford will after market F150 ones work on a F250LD?
