These unit hubs are not just another after market 1-ton unit hub that has been machined down and modified from an 8 lug to a 6 lug application. Trail-Gear has designed this unit for a specific application, so these 1-ton unit hubs will bolt right onto your Dana 60 or 9" housing that are set up for unit hubs. They are made to accommodate a 30 or a 35 spline axle shaft and use a 1/2-20 threaded wheel stud with a 6x5.5 wheel bolt pattern.
These are the same unit hubs that you will see on most competition buggies. They are ultra strong and easy to replace. Simply unbolt the old one and bolt on the new replacement hub. This is a much simpler and stronger unit then the stock spindles that they replace.
