Known for the cable-actuated locker, OX offers a high-traction solution for your 4x4 that doesn’t involve air or electric actuation. The differential’s internal shifting mechanism is 100 percent mechanical and features a shift fork— much like that found in manual transmissions, said to eliminate common pneumatic and electronic failure points in locking differentials. Though the company’s flagship product is the cable-actuated locker, pneumatic and electronic options are offered as well. Another unique goodie from OX is the Drive Away Lock, designed to manually lock your differential should the shifting mechanism suffer trail damage. Screw the device into the differential cover to manually activate the locker in a pinch.
Fitment: Dana 30, 35, 44, 60 axles; Ford 8.8-, 10.25-, and 10.5-inch axles; GMC 10-bolt axles; and more.
