Okay, so I am browsing around steeda's website, which I do from time to time, and I go to the drivetrain section, and I have to openly admit, I have no idea why anyone would need an aftermarket differential. What would be the benefits of having a "locking" differential, or any of the aftermarket differentials on steeda's website. So basically, I need some info as to why someone would need an aftermarket differential, what would be the benefits, the disadvantages, and all that info. If anyone knows, please inform me cause I am lost on the whole thing, and the all-mighty stangnet search gave no results...
