ARB RD149 Air Locker Locking Differential

The ARB RD149 Air Locker is a premium locking differential designed to provide maximum traction in the most challenging off-road conditions. Unlike limited-slip differentials that rely on friction or mechanical components, the Air Locker uses compressed air to engage a solid lock between the axle shafts, ensuring 100% power transfer to both wheels when you need it most.

Key Features:

• On-demand engagement and disengagement via dashboard-mounted switch for optimal control
• Delivers equal power to both wheels, eliminating wheel spin on uneven terrain
• Proven design trusted by off-road enthusiasts and professional competitors worldwide
• Factory-sealed unit requires no internal maintenance
• Compatible with ABS and traction control systems
• Forged steel construction for maximum strength and durability

Complete Kit Includes:

• Air Locker differential assembly
• Dash-mounted activation switch
• Solenoid valve
• Air line and bulkhead fittings
• All necessary hardware for installation

The ARB Air Locker gives you the ability to switch between open differential driving for normal conditions and locked differential for maximum traction when traversing rock crawling, mud, sand, snow, or steep inclines. When activated, the Air Locker transforms your differential into a spool, forcing both wheels to turn at the same speed regardless of available traction.
