Air Locker Locking Differential ARB - Jeep Grand Cherokee WJ 99-04

ARB Air Locker's patented design has proved ultra dependable, even in the most arduous conditions. It's strength lies in its simplicity & minimal moving parts ensures maximum reliability. All structural components are manufactured from aerospace grades of high alloy steel, and where possible, we increase the number of differential pinion gears to distribute torque loads evenly. Many recent Air Locker designs also utilise timed gear sets to further improve strength, a design feature that has led to a second US patent on the product.
