Jeep Air Lockers from ARB, the world's most highly company for traction aid, have proved ultra dependable even in the most arduous conditions. When extra traction is required, the driver simply activates the Air Locker via a convenient dash mounted switch. Pneumatic pressure supplied by an on board air compressor engages ARB's patented locking mechanism inside the Air Locker, thus preventing the wheels from turning independently. The Air Locker is deactivated by flicking a switch, returning the differential to normal.

An ARB Locker's strength lies in its simplicity and minimal moving parts ensures maximum reliability. All structural components are manufactured from aerospace grades of high alloy steel, and where possible, ARB engineers have increased the number of differential pinion gears to distribute torque loads evenly. Many recent Air Locker designs also utilize timed gear sets to further improve strength - a design feature that has led to a second US patent on the Lockers.

Other ARB Air Locker benefits include:
100% traction on demand without affecting on road drivability or driveline wear.
Vastly improved traction means less reliance on momentum, thus reducing the likelihood of vehicle damage and environmental impact.
Easy, convenient operation allows the user to concentrate on the terrain without leaving the comfort and safety of the driver's seat.
Ultra durable and extremely strong - only the highest quality materials used in construction.
Incredibly simple yet effective design that employs minimal moving parts, thereby ensuring maximum reliability.
Thoroughly tested and proven design & trusted and used in over 80 countries around the world.
Front and rear Air Lockers available for most makes and models.
2WD applications available.
Easy installation and maintenance & no special tools, skills or additives required.
Air compressor also provides convenient, reliable source of air for inflating tires, camping and leisure equipment.
