ARB Airlocker Jeep Jl Sahara M220 32Spl

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.

Take on challenging terrain with the ARB RD245 Air Locker Differential, engineered for Jeep Wrangler JL models equipped with the M220 rear axle and 32-spline axle shafts. This pneumatically operated differential delivers selectable traction when you need it while preserving conventional open-differential behavior when unlocked. With the flip of a switch, the Air Locker ties both axle shafts directly to the ring gear, helping maintain maximum available traction across uneven, slippery, or rocky surfaces.

The ARB Air Locker is designed for controlled off-road driving and dependable performance in demanding conditions. Its two-piece construction uses minimal moving parts to promote durability and reliability, while the steel-reinforced, elastomer-bonded annular seal is built to withstand extreme climate conditions. The patented timed locking mechanism provides positive engagement and fast unlocking, allowing drivers to respond quickly to changing terrain without leaving the driver's seat.

This ARB differential kit includes the Air Locker differential, activation switch, solenoid valve, air line, and bulkhead fitting. An ARB air compressor is required for operation and is sold separately. Once installed, the system provides selectable traction on demand without compromising normal on-road drivability or unnecessarily increasing driveline wear. The ARB RD245 is a purpose-built upgrade for 2018-2019 Jeep Wrangler applications using the M220 rear axle, helping reduce wheel spin and improve vehicle control in conditions where an open differential may lose traction.
