ARB RD234 Air Locker Differential with Pneumatic Locking System

The ARB RD234 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 air locker represents the pinnacle of differential locking technology for serious off-road enthusiasts.

How It Works:

The ARB Air Locker utilizes a pneumatically operated locking mechanism activated by a 12-volt ARB air compressor. When engaged via a simple switch from the driver's seat, the air locker prevents the differential gears from rotating, directly tying both axle shafts to the ring gear. This eliminates wheel spin and ensures maximum traction to both wheels simultaneously. When unlocked, the unit functions as a standard open differential for normal on-road driving.

Key Features:

• Two-piece design with forged gears for enhanced strength and durability
• On-demand activation and deactivation from inside the vehicle
• 100% traction delivery when engaged
• Functions as open differential when unlocked for street driving
• 12-volt air compressor operated system
• Industry-leading five-year warranty
• Enables slower, more controlled off-road driving to reduce vehicle damage and environmental impact

The ARB RD234 Air Locker provides the versatility of switchable traction control, making it ideal for vehicles that see both daily driving and challenging off-road conditions. By maintaining the highway manners of an open differential until traction is needed, it offers the best of both worlds for 4x4 applications.
