Jeep XJ TJ ZJ ARB air locker - Dana 30 - 30 spline

Fits: Dana 30 axle with 30 spline axles and 3.73 and numerically higher gear ratios.

Many types of traction devices have been available for years, but until the ARB Air Locking Differential, all were a compromise, performing well either off the road or on the road, but not on both. The Air Locking Differential provides normal differential action on the highway, maintaining safe, predictable handling. Once off the road, by simply pushing the buttons, the Air Locking Differentials lock the axles together providing 100% traction to all wheels allowing you to safely traverse even the most difficult terrain.

NOTE:  You will have to purchase the air compressor separately to power the air lockers.  Stock axles are 27 spline so they can be used, however cromoly axles are HIGHLY recommened
