ARB RD163 Air Locker Differential with Pneumatic Locking System

The ARB RD163 Air Locker Differential delivers 100% traction on demand without compromising highway driving performance. This advanced differential locker utilizes a pneumatically operated locking system that can be activated or deactivated from the driver's seat with the flip of a switch, providing maximum control in challenging off-road conditions.

Key Features:

• Improved two-piece design with forged gears for enhanced durability and strength
• Pneumatic activation system powered by 12-volt ARB air compressor
• Prevents differential gears from rotating when engaged, locking both axle shafts together
• Functions as a conventional open differential when unlocked for normal highway driving
• Solid and durable internal locking mechanism engineered for reliability
• Industry-leading five-year warranty for peace of mind
• Enables slower, more controlled driving to reduce vehicle damage and environmental impact

When the ARB Air Locker is activated, it prevents the axle shafts from turning independently by locking the differential gears in place. This ties both wheels directly to the ring gear rotation, ensuring maximum traction is maintained at all times. The system provides significant advantages for serious off-road enthusiasts who need reliable traction in mud, sand, rock crawling, and other extreme terrain conditions.
