Closer Look

The ARB Air Locker is a driver-controlled, selectable locking differential that provides ultimate traction on demand without sacrificing on-road driveability. This specific Air Locker is engineered for Dana 50 front axles, featuring a robust 30 spline design to deliver superior strength and reliability in demanding off road conditions.

When activated, the Air Locker delivers equal drive to both wheels on the axle, allowing you to take full advantage of the available traction across any terrain. This is crucial for navigating steep inclines, rocky obstacles, or slippery tracks where a standard differential would fail by directing power to the wheel with the least grip.

Built in Australia from high-strength, aerospace-grade materials, this ARB Air Locker for Dana 50 front axles is the durable and reliable traction aid trusted by off roaders globally for its proven performance and a 5-year warranty, ensuring you can tackle any adventure with confidence.
