Trail-Gear has designed this unit for a specific application, so these 1-ton unit hubs will bolt right onto your Dana 60 or 9in. 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. All unit hubs include integrated roll pin to prevent the spindle nut from coming loose.
Trail-Gear's unit bearing pockets are designed to be a slip fit onto a 3 inch O.D. axle tube. They are forged from 1035 steel, precision machined, and heat treated for maximum strength and durability. They have been specially designed to accommodate the larger tubing without sacrificing any strength.
