ARB RD204 Air Locker Differential with Pneumatic Locking System

The ARB RD204 Air Locker Differential is an advanced traction control system that 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 air locker provides superior strength and reliability for serious off-road enthusiasts.

How It Works:

The ARB Air Locker employs a pneumatically operated locking mechanism that activates via a 12-volt ARB Air Compressor, controlled by a simple switch from the driver's seat. When engaged, the Air Locker prevents the differential gears from rotating independently, effectively locking both axle shafts together and tying them directly to the ring gear rotation. This ensures maximum traction when you need it most—in mud, sand, rock crawling, or other challenging terrain. When unlocked, the unit functions like a standard open differential for normal on-road driving.

Key Features:

• Improved two-piece design with forged gears for enhanced durability
• 100% traction on demand with instant activation and deactivation
• Pneumatic locking system operated by 12V air compressor
• Convenient in-cab switch control for easy operation
• Functions as open differential when unlocked for normal highway driving
• Industry-leading five-year warranty
• Reduces environmental impact through controlled, safer driving

Benefits:

Beyond dramatically improving off-road capability, the ARB Air Locker allows for slower, more controlled vehicle operation in difficult terrain, 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 conditions.
