ARB Air Locker’s patented design has proven to be an ultra-dependable product, even under the most arduous conditions. It’s strength lies within the simplicity of the design, the minimal the moving parts ensures maximum reliability. All structural components are manufactured from aerospace grades of high alloy steel, and where possible, they 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 product.
