ARB Airlocker Jeep Jl Rubicon M210 M220 35Spl

The world's premier traction aid, an ARB Air Locker(TM) keep you moving in all conditions. With the flick of the switch an Air Locker gives instant lock at any moment and its super strong design allows activation at any speed allowing you to tackle the toughest terrain. The advantage of the Air Locker lies in the pneumatically operated locking system inside the differential. When activated, the Air Locker prevents the internal differential gears from rotating and therefore prevents the axle shafts from turning independently of each other. With both wheels tied directly to the rotation of the ring gear, the vehicle maintains maximum possible traction at all times. When unlocked, it operates like a conventional open differential. An Air Locker equipped vehicle can be driven in a slower, safer and more controlled manner, greatly reducing the likelihood of vehicle damage and environmental impact.

The ARB RD246 Air Locker Differential is a high-performance traction solution for 2018–2019 Jeep Wrangler JL Rubicon models equipped with an M210 front axle or M220 rear axle and 35-spline axle shafts. Designed for demanding off-road conditions, this pneumatically operated differential delivers selectable traction at the push of a switch. When activated, it locks the internal differential gears so both axle shafts rotate together, helping the vehicle maintain maximum available traction across uneven, loose, or challenging terrain.
When the ARB Air Locker is unlocked, it functions like a conventional open differential for predictable on-road drivability and reduced driveline stress. Its strong two-piece construction uses minimal moving parts for dependable operation, while the steel-reinforced, elastomer-bonded annular seal is engineered to withstand extreme temperatures and harsh environmental conditions. The patented timed locking mechanism provides strong engagement and rapid unlocking, allowing the driver to maintain focus on the trail without leaving the vehicle cabin.
The ARB RD246 kit includes the Air Locker differential, activation switch, solenoid valve, air line, and bulkhead fitting for installation. An ARB air compressor is required for operation and is sold separately. This system provides selectable, 100-percent traction on demand without compromising normal road manners when disengaged. Confirm the vehicle’s axle configuration, spline count, and application before installation to ensure proper fitment. Professional installation is recommended for correct differential setup and reliable long-term performance.
