ARB RD159 Air Locker Differential with Pneumatic Locking System

The ARB RD159 Air Locker Differential delivers 100% traction on demand without compromising highway driving performance. Featuring ARB's improved two-piece design with forged gears and backed by an industry-leading five-year warranty, this differential locker provides the ultimate solution for serious off-road enthusiasts.

How It Works:

The Air Locker utilizes a pneumatically operated locking system controlled by a 12-volt ARB Air Compressor. When activated from the driver's seat with the flip of a switch, the locking mechanism prevents the differential gears from rotating, tying both axle shafts directly to the ring gear rotation. This ensures both wheels maintain power and traction simultaneously, even when one wheel loses contact with the ground. When unlocked, the unit operates as a conventional open differential for normal highway driving.

Key Features:

• Improved two-piece design with forged gears for enhanced durability
• Pneumatic activation and deactivation via 12V air compressor
• On-demand locking controlled from the driver's seat
• Maximum traction when engaged, standard open differential when unlocked
• Industry-leading five-year warranty
• Allows for slower, more controlled off-road driving to reduce environmental impact

Benefits:

Beyond dramatically improving off-road capability, the Air Locker enables safer, more controlled vehicle operation in challenging terrain. This reduces the risk of vehicle damage and minimizes environmental impact by eliminating the need for aggressive throttle inputs and wheel spin.
