I'm trying to figure out if my 89 k5 already has a lift or not. height at the top of the front fenderwell was 50 inches i believe. it sits on 32s right now and hovers over them bad but i measured and they are only 29 inches tall. i also have a block under the rear springs about 2-3 in tall. any one know what stock height is so i can figue out if i even need to buy a lift. I think for now i'm just going to put it on 35 or 37 boggers.
