Well, if it was me, I'd upgrade the whole axle with something stronger. It really depends on what you want to do though. if you don't have any fabrication skills then a bolt-in option would be your only choice. If you're planning on going to 35's, then I'd pass on it. Now if you're sticking with 33's or under, then it shouldn't be a problem. Although, you'll really want to truss that D35. They flex quite a bit(this is what causes side adn spyder egars to break). You won't have that problem with the Detroit flex still isn't a good thing. Oh and keep in mind, you'll have to shim the diff again. It may or may not have the same dimensions as the stock carrier. Oh and you're still running C-clips, although with the larger shafts, they should break as often.
