Complete Control When You Need It

Having the ability to control the locking and unlocking of your differential allows you to have the traction you need when you need it. The ARB Rear Air Locker utilizes an ARB air compressor to activate, and deactivate, the built-in locking mechanism. The Air Locker, when activated, prevents the differential gears from rotating, which prevents the axle shafts from turning independently. The rotation of the wheels is tied to the ring gear, which allows for maximum traction at all times. The result is complete driver-control over the differential, which will enable you to tackle the harshest off-road trails without sacrificing street drivability and fuel economy. The ARB Rear Air Locker Differential includes everything you need to swap out your stock differential. All you will need is an ARB air compressor kit, and you will have exceptional off-road traction with OEM on-road drivability at your fingertips.

Industry-Leading Build Quality & Warranty

The ARB Rear Air Locker was designed for maximum durability, allowing it to withstand the toughest off-road applications. The Air Locker is air actuated, by your choice of ARB air compressor, using an included rocker switch and solenoid system. The fully-forged internal gears and two-piece case design limits the number of moving parts, improving reliability and performance over the competition. ARB includes all necessary installation instructions and hardware and offers an industry-leading 5-Year Limited Warranty to help protect your investment. The Air Locker Kit comes with everything you need except for a required on-board air compressor.
