ARB RD148 Air Locker Locking Differential - Kit

The ARB RD148 Air Locker is a selectable locking differential that provides superior traction when you need it most. Unlike traditional automatic lockers, the Air Locker gives you complete control—engage it with the flip of a switch when tackling difficult terrain, then return to normal driving for everyday conditions.

How It Works:

The ARB Air Locker uses compressed air to lock both axle shafts together, forcing both wheels to turn at the same speed. This ensures power is delivered to both wheels equally, even when one wheel loses traction. When disengaged, your differential operates normally for smooth street driving and turning.

Complete Kit Includes:

• Air Locker differential assembly with integrated air-actuated locking mechanism
• Dash-mounted activation switch for in-cab control
• Solenoid valve for air activation
• Air supply line and bulkhead fittings for installation
• All necessary hardware for complete installation

Key Benefits:

• On-demand traction control—engage only when needed
• Superior strength and reliability for extreme off-road use
• Proven design trusted by off-road enthusiasts worldwide
• Smooth street manners when unlocked
• Works with existing air compressor or ARB air system

The ARB Air Locker is ideal for serious off-road vehicles, rock crawlers, and 4x4s that regularly encounter challenging terrain including mud, sand, rocks, and steep inclines. Installation requires professional setup and integration with an on-board air system.
