The Eaton Detroit Locker is a fully automatic locking differential that maximizes traction by mechanically locking both wheels under load, keeping them in drive even if one wheel is airborne. It functions automatically in forward and reverse and is built for robust, low-maintenance use. This unit is specified for rear 9-inch housings with a 31-spline axle and 1.32" axle shaft diameter, covering 3.25 and up ring-and-pinion ratios for heavy-duty traction applications.
