What Is an ARB Air Locker?
An ARB Air Locker is a pneumatically operated locking differential that converts a standard open differential into a selectable locker. Engaged via a dashboard switch and onboard compressor, it sends equal torque to both wheels on an axle — essential for UAE dune bashing, wadi crossings, and Hajar Mountain trail work.
Unlike always-on mechanical lockers, the ARB unit disengages completely on tarmac, preserving normal steering behaviour and tyre wear for everyday driving. That on-demand design makes it the most popular aftermarket locker in the UAE 4×4 community.

Front vs Rear Air Locker: Which First?
For most UAE use — Liwa dune bashing, Fujairah wadi crossings, Hatta rock trails — the rear locker delivers the biggest traction improvement per dirham. A rear locker prevents the inside rear wheel from spinning free on steep inclines and cross-axle situations. Fit the front locker second if you tackle technical rock terrain or compete in organised desert events.
