RD105

Overview:

The ARB Air Locker is the world’s premier traction aid designed to keep your Jeep moving confidently through the toughest off-road conditions. Engineered for Jeep Wrangler models from 1987 to 2006 and Jeep Grand Cherokee models from 1993 to 2004, this pneumatic locking differential provides instant, on-demand 100% traction at the flick of a switch. Whether you’re navigating rocky trails, mud, or uneven terrain, the Air Locker ensures both wheels turn in unison, maximizing grip and vehicle control.

Ideal for off-road enthusiasts and serious trail riders, the ARB Air Locker enhances your vehicle’s capability without compromising on-road drivability. When disengaged, it functions as a conventional open differential, maintaining smooth handling and reducing driveline wear during everyday driving.

Key Features:

Designed for reliability and ease of use, the ARB Air Locker offers a range of advanced features that set it apart from traditional locking differentials:

• Instant pneumatic locking system activated via a simple dashboard switch
• Allows activation at any speed, enabling safe and controlled engagement on the move
• Steel-reinforced, elastomer bonded annular seal engineered to withstand extreme temperatures
• Two-piece ultra-durable design with minimal moving parts for maximum reliability
• Patented timed locking mechanism for high strength and rapid unlocking
• Compatible with Dana 35 axles featuring 30 spline shafts and gear ratios of 3.54 and up
• Suitable for both C-clip and non C-clip type axle shafts
• Maintains normal open differential operation when unlocked for smooth on-road performance
• Reduces vehicle damage and environmental impact by enabling safer, slower off-road driving

Construction & Design:

The ARB Air Locker is built to endure the harshest off-road environments. Its robust two-piece construction minimizes moving components, significantly enhancing durability and reliability. The steel-reinforced, elastomer bonded annular seal is specifically designed to resist extreme climatic conditions, ensuring long-lasting performance regardless of temperature fluctuations.

Inside, the pneumatically operated locking mechanism prevents the internal differential gears from rotating independently, effectively locking both axle shafts together. This design delivers maximum traction by tying both wheels directly to the ring gear’s rotation, providing superior grip on challenging terrain.

Installation & Fitment:

The ARB Air Locker is a direct fit for Jeep Wrangler models from 1987 through 2006 and Jeep Grand Cherokee models from 1993 through 2004 equipped with Dana 35 axles featuring 30 spline shafts and gear ratios of 3.54 and above. It suits both C-clip and non C-clip axle shaft configurations.

Installation requires an air compressor system (sold separately) to operate the pneumatic locking mechanism. The kit includes all necessary components for integration, and professional installation is recommended to ensure proper setup and optimal performance.

What's Included:
