Important Fitment Note: Vehicle must be upgraded to 35 Spline Axle Shafts in order to use this locker model. Fits:2018 and newer Jeep Wrangler JL Rubicon models equipped with Dana M210/M220  2019 and newer Jeep Gladiator JT Rubicon models equipped with Dana M210/M220  ARB Air Locker’s patented design has proved extremely reliable, even under the most arduous conditions. The Air Locker’s strength comes via structural components manufactured from aerospace grades of high alloy steels. ARB engineers increase the number of differential pinion gears, where possible, to distribute torque loads evenly, thus adding to the overall strength of the differential. Many recent Air Locker designs utilize timed gear sets, which further improve strength. This latest introduction to our design and manufacturing process has led to the acquisition of a second US patent on the product. The design process of an Air Locker involves countless hours of testing. Computerized Finite Element Analysis (FEA) allo
