Trying to do it right, but on a budget as all of us are. I have excellent mechanical / fabrication skills which is why I was considering the IFS. There is nothing wrong with the current I-beam other than the fact that the frame is 13" off the ground and I want it much lower - maybe if I can find a 4" or 5" drop I-beam that'll work along with some spring work - which is why I was 1st considering the IFS. The truck would be a daily driver - all blacktop, 30% twisty 2 lanes, 70% interstate 70-75 mph. I will be doing all of the work which is why I was considering the I-beam to save time and effort (somewhat). Other mods: Pontiac 400/TH400 and narrowed Dana 70 dually (it is not currently a dually) tangible = real technical facts opinion = personal preferences I can see the technical benefits of IFS. I use to be a powered vehicle engineer for a suspension company. I have not had any experience with driving an I-beam vehicle, which is why I was asking those here that have had a lot of personal and in depth experience with one.
