ARB RD214 Air Locker Differential with Pneumatic Locking System

The ARB RD214 Air Locker Differential delivers 100% traction on demand without compromising on-road performance. Featuring an improved two-piece design with forged gears and backed by an industry-leading five-year warranty, this pneumatic locking differential represents the pinnacle of ARB's engineering excellence.

How It Works:

The Air Locker employs a 12-volt ARB air compressor to activate a durable locking mechanism inside the differential. When engaged, the pneumatic system prevents the differential gears from rotating, locking both axle shafts together to rotate at the same speed as the ring gear. This ensures both wheels maintain maximum traction regardless of terrain conditions. When unlocked, the unit functions as a standard open differential for normal highway driving.

Key Features:

• Two-piece design with forged gears for enhanced strength and durability
• Pneumatic activation system controlled by a simple cab-mounted switch
• Seamless engagement and disengagement from the driver's seat
• Maintains factory highway driving characteristics when unlocked
• Five-year manufacturer warranty for peace of mind
• Compatible with 12-volt ARB air compressor systems

Benefits:

Beyond exceptional off-road capability, the Air Locker promotes responsible vehicle operation. By providing controlled, predictable traction, drivers can navigate challenging terrain at slower speeds with greater precision, reducing the risk of vehicle damage and minimizing environmental impact. The on-demand engagement means you only use the locker when needed, preserving fuel efficiency and tire wear during normal driving.

Professional installation recommended. Requires ARB air compressor and in-cab control switch (sold separately).
