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.

All Sport JL Rear with Advantek M200 - Dana 35 axle use this locker - RD244.
All Sport JL Rear with Advantek M220 - Dana 44 axle use RD245
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.

ARB Air Locker’s patented design has proven to be an ultra-dependable product, even under the most arduous conditions. It’s strength lies within the simplicity of the design, the minimal the moving parts ensures maximum reliability. All structural components are manufactured from aerospace grades of high alloy steel, and where possible, they have increased the number of differential pinion gears 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.
The ARB air locker differential is made from aerospace-grade high alloy steel for the ultimate in strength and durability. It is designed with simplicity in mind and features few moving parts for added reliability. This air locker differential provides excellent traction control both on the street and on the trail, so your Jeep can power through harsh road or weather conditions.
Please Note: This is not a direct fit to any OE applications. Must use 35 spline axle shafts.
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.
ARB Air Locker offers a compete air line and air locker kit with bulkhead fittings, activation switch, a solenoid valve, and replacement differential. The smooth, patented design provides durability even in the toughest road and off road conditions. With easy moving parts, it offers the securest ride and reliability. Manufactured from high alloy steel and differential pinion gears you'll experience the smoothest torque loads ever. It features 35 Spline for gear ratios 3.73 and down. Designed for Jeep Wranglers from 1987-2016, it will require an on board air compressor.
