Everyone seems to make the longer springs (chevys, alcans etc.), sound so easy that I might go for it. The only disadvantage that I can see is that my rig will be down for a few days, which is no big deal. One question I have is about the rear spring mount. Some people say to relocate it and some are using the stock location. Also, wouldn't you have to either modify your existing rear shackle for the chevys (different size eye) or make a new one?
