ARB RD131 Air Locker Locking Differential - Kit

The ARB RD131 Air Locker is a pneumatically-operated locking differential designed to provide maximum traction in challenging off-road conditions. When activated, the Air Locker locks both wheels on an axle together, forcing them to rotate at the same speed regardless of available traction. This ensures power is delivered to both wheels equally, preventing wheel spin and keeping you moving forward through mud, sand, rock, and snow.

Key Features:

• On-demand activation—unlock for normal on-road driving, lock for maximum traction off-road
• Pneumatic operation provides smooth, reliable engagement without driver effort
• Forged gear construction for superior strength and durability
• Complete kit includes replacement differential housing, dash-mounted activation switch, air solenoid valve, air line, and bulkhead fittings
• Maintains factory ride quality and handling when unlocked
• Proven design trusted by off-road enthusiasts and professional expeditions worldwide

ARB Air Lockers represent the gold standard in selectable traction aids, offering the perfect balance of on-road manners and off-road capability. Unlike limited-slip or automatic locking differentials, the Air Locker gives you complete control over when maximum traction is needed, making it ideal for vehicles that see both daily driving and serious off-road use.
