ARB RD134 Air Locker Locking Differential

The ARB RD134 Air Locker is a selectable locking differential designed to provide maximum traction in challenging off-road conditions. When activated, the Air Locker mechanically locks both wheels on an axle together, ensuring they rotate at the same speed regardless of available traction. This allows you to maintain forward momentum through mud, sand, rock crawling, and other extreme terrain where open or limited-slip differentials would struggle.

Key Features:

• On-demand activation—enjoy normal driving on-road, full lock off-road with the flip of a switch
• Pneumatic engagement system provides reliable, durable locking mechanism
• Forged steel construction for superior strength and longevity
• Includes complete installation kit with differential assembly, dash-mounted activation switch, air compressor solenoid valve, air line, and bulkhead fittings
• Proven performance in extreme conditions worldwide
• Maintains factory axle performance and reliability

ARB Air Lockers are engineered to withstand the rigors of serious off-road use while remaining completely transparent during normal driving conditions. When unlocked, the differential operates exactly like a standard open differential, providing smooth, quiet operation and excellent on-road manners. The RD134 represents decades of engineering refinement, making it the world's most trusted aftermarket locking differential solution.
