Has anybody ever thought of using the factory top leaf off of factory front springs, the 47" leaf and then add all the springs from the 52" spring pack except the top 52" spring? In a sense have 47"/52" spring pack without having to move the axle? I know this doesn't accomplish all the benefits of a 52" spring swap but wouldn't it give you a budget 4" lift if you had these spring packs laying around and a nice factory spring rated ride? The only concern I would have is since the 47" top leaf is de-arched, if after putting the rest of the 52" spring pack under it, if it would net you 4" or any lift at all? What do you guys think?
