ARB RD203 Air Locker Differential with Pneumatic Locking System

The ARB RD203 Air Locker Differential is engineered to deliver 100% traction on demand without compromising highway driving performance. Featuring an improved two-piece design with forged gears and backed by an industry-leading five-year warranty, this differential locker represents the pinnacle of ARB's off-road traction technology.

How It Works:

The Air Locker employs a pneumatically operated locking mechanism activated by a 12-volt ARB air compressor. At the flip of a switch from the driver's seat, compressed air engages the locking system inside the differential, preventing the differential gears from rotating. This locks both axle shafts together, tying them directly to the ring gear rotation for maximum traction. When unlocked, the unit functions as a conventional open differential for normal on-road driving.

Key Features:

• Improved two-piece construction with forged gears for enhanced durability
• 100% traction on demand with electronic activation from the cab
• Prevents axle shafts from turning independently when engaged
• Functions as standard open differential when unlocked
• 12-volt air compressor operated system
• Industry-leading five-year warranty coverage
• No highway performance sacrifice

Benefits:

Beyond off-road capability improvements, the ARB Air Locker promotes environmental responsibility by enabling slower, safer, and more controlled vehicle operation. This reduces the risk of vehicle damage and minimizes environmental impact during off-road adventures. The selective engagement system means you only use locking traction when needed, preserving tire wear and drivetrain components during normal driving.
