Whether navigating rocky trails, mud, or slippery surfaces, the Airlocker ensures both wheels turn in unison, maximizing grip and control without compromising on-road drivability.

Compatible with a wide range of Jeep Wrangler models from 2018 through 2023, including Sport, Rubicon, Sahara, Willys, and special editions, the Airlocker is an essential upgrade for those seeking enhanced off-road capability and safer, more controlled driving in adverse conditions.

Key Features:

Designed for durability and ease of use, the ARB Airlocker Differential offers a range of advanced features that set it apart from conventional locking differentials:

• Instant pneumatic locking system activated via a simple dashboard switch
• Allows activation at any speed, enabling traction when you need it most
• 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
• Provides 100% traction on demand without affecting driveline wear or on-road handling
• Includes all necessary components for installation: Air Locker differential, activation switch, solenoid valve, air line, and bulkhead fitting
• Compatible with Jeep Wrangler 10 bolt rear axles featuring a 5.28-inch diameter ring gear and 29 spline axle shafts

Construction & Design:

The ARB Airlocker is built with ruggedness and longevity in mind. Its two-piece design minimizes moving parts, reducing potential failure points and ensuring dependable operation in the harshest environments. The steel reinforced, elastomer bonded annular seal is specifically engineered to endure extreme climatic conditions, from freezing cold to scorching heat, maintaining airtight performance and preventing contamination.

Inside, the pneumatically operated locking mechanism securely locks the differential gears, preventing independent wheel rotation and delivering maximum traction. When disengaged, it functions like a standard open differential, preserving smooth on-road handling and driveline longevity.

The ARB Airlocker Differential is designed as a direct fit for Jeep Wrangler models from 2018 to 2023, including Sport, Sport S, Rubicon, Sahara, Willys, and various special editions such as the 80th Anniversary, Freedom, Islander, High Altitude, Moab, and Rubicon 392. Installation requires an air compressor system (sold separately) to operate the pneumatic locking mechanism.

Installation involves replacing the factory differential with the Airlocker unit and integrating the included activation switch and pneumatic components. Professional installation is recommended to ensure proper setup and optimal performance.
