ARB Air Locker Clutch Gear Type with Wave Spring Differential

The ARB Air Locker is a selectable, air-operated locking differential (also called a locking diff or air-actuated differential locker). This clutch gear type design uses a wave spring to give dependable engagement and disengagement. It gives you a fully open differential for normal driving and 100% positive lock when you need maximum traction off-road.

Key Features:

• Selectable operation: The differential works as a standard open differential until the driver activates the locker, so on-road manners and tire wear are not affected.
• Air-actuated locking: Compressed air from an ARB air compressor, sold separately, engages the locker and fully locks both axle shafts together.
• Clutch gear design with wave spring: The wave spring helps the locking mechanism release cleanly once air pressure is removed.
• Strong construction: The locker is built from high-strength materials to handle the loads of rock crawling, trail driving, towing and overlanding.
• Sealed air delivery: A dedicated air line feeds a sealed passage in the differential housing for consistent operation.
• Dash-mounted control: The locker is controlled by a switch inside the cab, so you can lock and unlock quickly when conditions change.

ARB is a respected name in four-wheel-drive equipment and has designed and tested its Air Lockers in demanding conditions for decades. Whether you build a trail rig, an expedition vehicle or a work truck, an ARB Air Locker adds traction on loose, slippery or uneven terrain while keeping normal driving manners.
