ARB RD254 Air Locker Locking Differential

The ARB RD254 Air Locker is a premium selectable locking differential designed to provide maximum traction in challenging off-road conditions. Unlike open differentials that can leave you stranded when one wheel loses traction, the Air Locker engages on-demand to lock both axle shafts together, ensuring power is distributed equally to both wheels for superior grip and control.

Key Features:

• On-demand selectable activation—engage only when you need it, leave disengaged for normal driving
• Pneumatic operation provides smooth, reliable engagement without electronic components in the differential
• Maintains factory-like handling and fuel economy when unlocked
• Forged gear construction for exceptional strength and durability
• Suitable for extreme off-road use including rock crawling, mud, sand, and snow
• Proven design trusted by off-road enthusiasts and professional competitors worldwide

The ARB Air Locker system requires an air source (onboard air compressor) and dash-mounted switch for operation. When activated, compressed air engages the locking mechanism inside the differential housing, creating a solid connection between both axle shafts. This allows both wheels to rotate at the same speed regardless of traction conditions, dramatically improving your vehicle's ability to navigate obstacles and maintain forward momentum.
