In answering your question I have had both straight axles and IFS. The hot rod guys put them on because they are more visible for that special look (the spring is over the axle). On a truck really can be seen and the design paralell spring no matter what you do to it is still isn't going to come close to the ride an IFS will give you. What mostly determines what people put on their trucks is the better the ride the more it cost, I have a TCI setup if I was going to do an IFS again I would save and get the new Porterbuilt design and I still might do that done the line.
