ABOUT THIS PRODUCT

Locking differentials have been available for years, but were always a compromise: performing well either off the road or on the road - but not on both. The ARB Air Locker provides normal differential action on the street - maintaining safe, predictable handling. An ARB Air Locker differential will drive out of the most difficult situations.
