The ARB Air Locker's patented design has proved to be ultra dependable, even in the most strenuous conditions when off-roading on extreme terrains. Its strength lies in its simplicity and minimal moving parts that ensure maximum reliability. All structural components of the snatch block are manufactured from aerospace grades of high alloy steel, and where possible, the number of differential pinion gears is increased to distribute torque loads evenly.
Many recent Air Locker designs also utilize timed gear sets to further improve strength, a design feature that has led to a second US patent on the product.

Improves Vehicle Traction for Tough Off-Road Trails
When tackling aggressive and uneven off-road trails, sometimes you need that extra boost of traction to push you over tough landscapes. ARB's Rear Air Locker is deigned to do just that as it provides 100% traction on demand without affecting on-road drivability or driveline wear. It works by locking the gears along the axle to improve your vehicle's traction even on wet or slick roads. Moreover, the patented timed locking mechanism offers high strength and ultra fast un-locking, so you can keep moving along the trail without compromise. This incredibly simple yet effective design employs minimal moving parts in order to provide consistent performance and maximum reliability.
High-Quality Construction & Warranty Info
Constructed from high-strength steel, the ARB Rear M220 32 Spline Air Locker was built for maximum strength and long-lasting functionality. To endure the harshness of forgiving terrain, this air locker differential also sports a 2-piece design with expertly forged gears that will provide consistent performance over any application. Moreover, the steel reinforced, elastomer bonded annular seal was designed to handle the most extreme temperatures on earth. This entire unit was also torture-tested to ensure this differential won't let you down. Professional installation is recommended for this unit, but if you do plan to complete this at home, all if the necessary hardware and mounting instructions are included. Best of all, this kit is backed by a 5-Year Limited Warranty to help protect your investment.
Note:
All Sport JL Rear with Advantek M220 axle use this kit. All Sport JL Rear with Advantek M200 axle use RD244. This locker fits the JT Gladiator Sport both front and rear.
This fits the rear axle in Bronco models without a locker. Non-OEM locker applications have the ring gear welded to the factory differential. -You must also replace the ring and pinion to install this locker.
Easiest way to tell the difference:
Advantek M220 (D44) rear axle has drain plug on side
Advantek M200 (D35) rear axle has drain plug on bottom
All Sport JLs with manual transmission or LSD option get the M220 rear axle. Not all automatic trans Sport JLs get the M220 (D44) rear.
The patented ARB Dana 30 Air Locker 27 Spline 3.73 and Up is built to withstand the worst of conditions. Constructed from aerospace-grade high-alloy steel, the materials in the piece are good enough for spaceships -- and they'll work for your vehicle. The overall design enhances long-term durability by reducing the number of moving parts while still evenly distributing torque loads. A number of designs also have patented timed gear sets that improve total strength.
The ARB Air Locker is a pneumatic air-locking differential that employs a 12 volt ARB Air Compressor designed to operate a solid and durable locking mechanism inside the differential.
This design can instantly lock differentials, and allow you to handle the most challenging terrains. The kit comes complete with an air locker kit, replacement differential, activation switch, solenoid valve, and airline, with bulkhead fittings.
In order to run this part on your vehicle, these additional parts are required:
• CKSA 12 air compressor (extremely compact). Operates up to 2 air lockers. Not intended for oversized tire inflation.
• CKMTA12 air compressor (Still compact, operates up to 2 air lockers when paired with 171503, and will inflate tires and run air tools when paired with a 171302, and will run even faster when paired with 171501 air tank.
