ARB Air Locker 24 Spline
This model will only fit Land Rover axles with 24 spline half-shafts. If you would like to purchase an ARB Air Locker for any other vehicle please contact us as we carry stock for most makes of 4x4.
Created to provide 100% traction on demand, without sacrificing any of your vehicle’s highway driving performance, ARB Air Lockers employ a 12 volt air compressor designed to activate (and deactivate) a solid and durable locking mechanism inside the differential. This gives you the traction you need, when you need it, all at the flick of a switch, and all within the safety and comfort of the driver’s seat.
The advantage of the ARB Air Locker lies in the pneumatically operated locking system inside the differential. When activated, the Air Locker prevents the differential gears from rotating and therefore prevents the axle shafts from turning independently of each other. With both wheels tied directly to the rotation of the crown wheel, the vehicle maintains maximum possible traction at all times. When unlocked, it operates just like a conventional ‘open’ differential.
In addition to providing outright improvements to a 4x4’s off road capabilities, the Air Locker offers significant environmental benefits. An Air Locker equipped truck can be driven in a slower, safer and more controlled manner, greatly reducing the likelihood of vehicle damage and environmental impact.
Range & Installation:
Air Lockers are currently available in over 100 configurations to suit a wide range of 4x4 vehicles from around the world, and can be installed in both the front and rear axles. Installation should be performed by a qualified differential technician, although no special tools or skills are required apart from those necessary for fitting a standard differential. ARB also offers two compressor models suitable for Air Locker operation, one of which can also be used to inflate tyres and other equipment.
