    Premium Traction. The ARB Airlocker differential system provides excellent traction and grip on off-road terrain. It can be operated by a simple switch that activates the systems' patented ARB pneumatic control system to prevent the wheels from turning independently. This air locker is made specifically for use with your Dana 44 axle with a 30 spline count and is designed for use with 3.73 & lower (numerically higher) gear ratios.

    Durable Construction. All the parts in this system are built from aerospace grade alloy steel for extreme durability and strength. The ARB Airlocker Differential System comes with locking differentials, solenoid, and an activation switch to make installation smoother. This locker requires the use of an on board air compressor system to actuate the locker.

    Application. The ARB Airlocker differential Dana 44, 30 spline for 3.73 & lower gear ratio is designed for 1987-2018 Jeep Wrangler YJ, TJ, & JK models.

        I was just told 4.10 gear ratio would work on this; is this true?

        • This differential is designed to work with 3.73 and lower gears and not 4.10 gears.

            Not happy with kit. Doesnt fit the 05 rubicon with a dana44m rear diff. Instructions are vague. They dont identify parts orientation. Unit didnt fit with carrier brg. Washers. No tech line for help. Had to call ARB. They were supposed to send a PDF. But that never showed. Been an installer for 20 yrs. .
