ARB RD104 Air Locker Locking Differential Complete Kit

The ARB RD104 Air Locker is a selectable locking differential that provides maximum traction when you need it most. Recognized as the world's premier traction aid, ARB Air Lockers give you the ability to lock your differential on-demand, keeping both wheels spinning equally for superior grip in challenging off-road conditions including mud, sand, rock, and snow.

How It Works:

Unlike limited-slip or automatic locking differentials, the ARB Air Locker operates like an open differential during normal driving for smooth, quiet performance. When activated by compressed air, the locker engages to lock both wheels together, providing 100% traction to both wheels on the axle. This gives you complete control over when you need maximum traction without compromising on-road manners.

Complete Kit Includes:

• Air Locker differential assembly with internal air-activated locking mechanism
• Dash-mounted activation switch for driver control
• Solenoid valve for air distribution
• Air line kit with bulkhead fittings for installation
• All necessary mounting hardware and connectors

Key Benefits:

• On-demand engagement—lock only when you need it
• 100% torque transfer to both wheels when locked
• Maintains open differential performance for normal driving
• Proven durability in extreme off-road conditions
• Compatible with air compressor systems

The ARB Air Locker is engineered for serious off-road enthusiasts who demand reliable traction performance. Whether you're crawling over rocks, climbing steep inclines, or powering through deep mud, the RD104 Air Locker ensures you maintain forward momentum when lesser differentials would leave you stuck.
