So if you plan on running a larger tire in the future, save your money and find a 44 somewhere. I know alot of guys who run the D30 without any issues. Todd runs one in his CJ and he beats that thing on 35's. I ran a 30 years ago before I swapped to the waggy front and never had an issue with it and the aussie locker. But I only ran 33's on it for fear of going to big on it. So if you are a mild non heavy footed driver keep the 30, plan on going bigger tire etc, save for a 44. But there has to be better deals out there or somebody selling a stock 44 housing cheaper than $5-6000!! Build one.
