Locking Differential for Dana 44 Axles (30 Spline, 3. Ratio)

The OX D44-392-30 is a high-performance locking differential engineered for Dana 44 axle assemblies that utilize 30-spline shafts and gear ratios of 3.92 or numerically higher. By providing selectable traction, this unit allows drivers to engage the locker only when needed, maintaining off-road capability in a wide variety of conditions. Each differential is supplied with a heavy-duty cover to provide extra protection against trail hazards. This locker supports multiple shifting configurations, including manual, air, and electric activation methods, which can be selected to suit specific vehicle setups. Proper operation requires the selection of a compatible shifting system, such as a manual cable, air actuator, or electric solenoid, which are sold separately to complete the installation. Users should consult the shifter selection guide to ensure the chosen components align with their vehicle's specific layout and routing requirements.
