Enhanced Traction for Off-Road Adventures

The ARB Air Locker Differential is an advanced upgrade for your 1999-2024 Ford F250/F350 equipped with a Dana 60HD axle. Designed to give you full control over your vehicle’s traction, this Air Locker allows you to handle the toughest terrains with ease. At the flip of a switch, it instantly locks the differential, ensuring both wheels spin at the same rate. This is especially helpful in off-road conditions where one wheel might lose traction, like when climbing rocks, driving through mud, or traversing uneven surfaces. The ability to lock and unlock the differential on demand allows you to enjoy full traction control without sacrificing on-road drivability, giving you the best of both worlds each time you set off for adventure.

Premium Construction & Design

One of the standout features of this system is the pneumatic operation. By locking the internal differential gears, the Air Locker essentially forces both axle shafts to rotate together, which maximizes traction when you need it most. When disengaged, the differential operates like a normal open differential, allowing for smooth driving on paved roads without extra wear on the driveline. This balance of performance and durability is further enhanced by its two-piece design, which minimizes moving parts. Plus, ARB has incorporated a patented locking mechanism that ensures quick engagement and disengagement, providing instant traction control without any delay. The kit comes complete with the differential itself, an activation switch, solenoid valve, air line, and bulkhead fitting, but note that an air compressor (sold separately) is required to operate the locking mechanism.
