So it's been years since i've lifted a rig so i'm out of the loop on what people consider to be the best springs to use. I have a friend who is wanting to lift his 81 3/4 ton truck and he wants to run a 33" or 35" tire (probably 35's) so I told him to go with a 4" shackle flip in the rear and then whichever springs are best for the front. So what says the brotherhood on spring preference?
