No single upgrade can have as big of an offroad performance benefit as a locking differential. ARB is one of the originals and always our preferred option. The selectable design of the locker ensures easy, smooth operation under normal driving conditions, but maximum traction when needed. Their complete line offers fitment for nearly every application imaginable, and delivers 100% lock up on-demand. A relentless commitment to reliable design and the highest quality of component materials means that ARB Air Lockers are ready to handle the abuse you can throw out. From overland expedition builds to competition crawlers to desert and rock racing, ARB has logged the podium finishes and epic journeys to back up their pedigree. If that wasn’t enough, all ARB air lockers are backed by a 5 year warranty. Even when time has passed beyond warranty, ARB Air Lockers are fully serviceable and rebuildable.

Jeep’s JK Wrangler may well go down in history as one of the most significant Jeeps ever. It’s impact on the aftermarket and explosion of popularity have cemented the iconic Wrangler look as a household name for most people. All non Rubicon models came with a Dana 30 front, and Dana 44 rear axle, spec’d uniquely to the JK. All Rubicon models came standard with Dana 44’s front and rear, with electronic lockers. These lockers can prove problematic over time, and are a great item to upgrade to 35 spline shafts and ARB lockers. While the lockers are shared with other Dana 30 and 4 variants, it is vital to order the correct bearing kits for your application.
