The OX GM 8.5 locker, for your 301 spline axle for 2.73 & up gear ratios, can instantly lock differentials and allow you to tackle the toughest off-road terrain. The world's best traction aid, OX Lockers keep you moving in all conditions.
Air/Cable Lockers from OX are currently available in over 20 configurations to suit a wide range of off-road and 4x4 vehicles from around the world. Because the OX Locker is only engaged when needed, it can be installed in BOTH the front and rear axles, with separate switches independently controlling the locker from within the off-road truck or vehicle.
