Description
The ARB Air Locker Differential (arbRD217) is the ultimate traction solution for Land Rover LR3 and LR4 owners looking to conquer the toughest terrains. With the flick of a switch, the Air Locker provides instant full axle lock, delivering 100% traction precisely when you need it—without compromising on-road drivability.
The pneumatically activated system locks the front axle’s differential gears, forcing both wheels to rotate at the same speed. This gives you maximum traction to tackle rocks, mud, and challenging off-road conditions. When disengaged, the Air Locker operates like a standard open differential, allowing smooth and safe everyday driving.
Engineered for extreme durability, the ARB Air Locker features a patented timed locking mechanism, ultra-reliable seals designed to withstand the harshest climates, and minimal moving parts for maximum longevity.
This kit includes the Air Locker differential, activation switch, solenoid valve, air line, and bulkhead fitting. An air compressor is required for operation and is sold separately.
Note: Not compatible with vehicles equipped with OE locking differentials.
