ARB Air Locker (Jeep Wrangler JL & JLU & Gladiator JT)

Air Locker locking differentials allow you to tackle the toughest terrain. As the world’s premier selectable locking differential, ARB Air Lockers keep you moving in all conditions.

Design & Development:
ARB maintains a strong presence in the off-roading industry with its proactive approach in R&D. Supporting accessories alongside new vehicle releases is key to staying ahead of the game. Our drivetrain engineers have assessed Jeep's new Wrangler JL and are proud to announce the release of Air Locker applications for both the front and rear axles of the Jeep Wrangler JL.

Replacing the JK, Jeep has built on the Wrangler's legendary history with their most capable vehicle to date, while maintaining its heritage with touches such as a seven-slot grille, iconic round headlights and open air models. To complement these unique touches, Jeep has upgraded the off road ability and central to this is next-generation Dana axles. To further enhance the JL capability off road, ARB is happy to release front and rear locker applications for all factory axle options.
