I suggest calling Doug at Quick Performance 515-232-0126. He will probably recommend a taller tire with 35 spline pinion pro gears, nodular or aluminum case. The Bronco case is cast iron and not very strong. You will just end up breaking something again. If you are running 28 spline axles, you need to upgrade them too. It is not the cost of building the rear strong enough, it is the costs caused by the wreck you can have when something breaks next time.
