ARB Air Locker Differential for Dana

The ARB Air Locker is an air-operated selectable locking differential for Dana axles. It gives you a standard open differential for normal driving and locks both axle shafts together when you need maximum traction off-road. Use it for rock crawling, mud, sand, steep climbs, and other low-traction conditions.

Key Features:

• On-demand locking: Compressed air engages the locker at the push of a switch. The differential stays open until you lock it, so on-road handling and tire wear stay normal.
• Full lock: When engaged, both wheels receive equal drive torque, so you keep traction even if one wheel is off the ground.
• Strong construction: The housing is a high-strength ductile iron casting. Internal components are built for heavy off-road use.
• Sealed air delivery: A seal housing and air line fitting carry air to the locking mechanism. The design is proven in demanding 4x4 use.
• Air source: It works with an ARB on-board air compressor or another suitable air supply, and is operated from a cab-mounted switch.
• Axle compatibility: It is offered in multiple Dana axle and spline configurations. Check the specific part number for your axle.

ARB is a respected Australian maker of 4x4 equipment. The Air Locker is one of its best-known products, and it is a popular choice for upgrading the traction of an off-road vehicle.
