Air Locking Differentials, Compressors & Covers
ARB Air Locker™ locking differentials are selectable units, which allow a fully open differential to be switched to a 100% locked spool at the flick of a dash mounted switch. Featuring ARB's patented Timed Gear Technology, an ARB Air Locker is the strongest and most reliable locking differential on the market today.

The patented design of ARB Air Lockers™ has proved extremely reliable, even under the most arduous conditions. The Air Locker™ strength comes from structural components manufactured from aerospace-grade high alloy steels. Where possible, ARB engineers increase the number of differential pinion gears to distribute torque loads evenly, improving the overall strength of the differential. ARB Air Locker™ designs feature Timed Gear Technology gear sets to ensure ideal meshing of the gear teeth and to improve the overall locker strength.

ARB air compressors provide truck owners with many advantages regardless of whether you're four wheeling, camping, fishing or hunting. ARB has a line of models, from vehicle mounted options to a portable air compressor, each suitable for numerous tasks including specific models available for Air Locker activation and tire inflation. ARB on-board compressors are designed to operate both front and rear Air Lockers™.

ARB differential covers were originally designed to protect the valuable ARB Air Locker™. However, during research and development ARB learned that their differential covers were so strong that they actually improved the strength of some of the smaller axle assemblies. Manufactured from high tensile, solid nodular iron and coming complete with magnetic dipstick and drain plug, the ARB diff cover is ideal for competition rock crawling or use on extreme off road trails.
