ARB RD246 Air Locker Differential Locking System

The ARB RD246 Air Locker is a pneumatically-operated locking differential that delivers on-demand traction for serious off-road driving. Unlike limited-slip differentials that provide partial power transfer, the Air Locker completely locks both axle shafts together, ensuring 100% torque distribution to both wheels when engaged. This gives you maximum traction on challenging terrain including mud, rock, sand, and snow.

Key Features:

• Selectable activation—engage only when you need it, maintaining normal on-road driving characteristics
• Pneumatic air-operated design provides instant response and positive engagement
• Forged gear train and case for superior strength and durability
• Works with factory gear ratios and aftermarket gearing
• Engineered and manufactured to OEM standards for reliable performance
• Includes differential internals, air line fitting, and installation hardware

The Air Locker operates on compressed air supplied by an ARB on-board air compressor, allowing you to switch between open differential mode for normal driving and fully locked mode for maximum traction. This versatility makes it ideal for vehicles that see both street and trail use. ARB Air Lockers are backed by extensive research and development, with applications engineered specifically for a wide range of vehicle makes and models.

Note: This differential assembly requires professional installation and must be matched to your specific vehicle application, axle type, and gear ratio. An ARB air compressor and in-cab control switch (sold separately) are required for operation.
