(To skip ahead to the ARB Locker section, go to minute 11:20 or click here.)


ARB Air Lockers use a pneumatically controlled locking mechanism to switch between an open carrier and a fully locked differential. Once installed, all it takes is the simple flip of a switch to go from an open differential that works well on the street to a spool that provides 100% traction to both wheels off-road. Each ARB locker comes complete with switches, solenoids, fittings, nylon air line, and even shims and bearings (if applicable).

Each ARB Locker is machined from a solid piece of nodular iron and encases 4 pinion gears (twice as many as most OEM differentials) with unique geometry that make them up to 30% stronger than OEM gears. The side gears that transfer force to the axle shafts are made from the highest grade nickel alloy steel and are finished with an aerospace grade surface treatment. ARB's proprietary timed locking system prevents gear grinding during engagement and extends the life of the unit.
