ARB AIR LOCKER DANA 44 30 SPLINE DIFFERENTIAL (LJ/TJ)

The ARB Air Locker's patented design has proved to be ultra dependable, even in the most strenuous conditions when off-roading on extreme terrains. Its strength lies in its simplicity and minimal moving parts that ensure maximum reliability. All structural components of the snatch block are manufactured from aerospace grades of high alloy steel, and where possible, the number of differential pinion gears is increased 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.
