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.
The reigning champs of the heavy duty axle world, Dana's 60, 70 and 80 series axles bring the beef. With their massive ring gears, stout pinions and heavy duty housings, they are the obvious choice as the core axles for a crawler build, or if you're lucky enough to start with a heavy duty platform where they are stock, even better! One thing Dana did not do though, was give the option of factory selectable lockers, which makes ARB Air Locker a natural choice for increased traction.
Due to the huge amount of variation in Dana's heavy duty axles, it's always best to find a BOM number or verify the exact application before ordering.

Notes:
- For all applications verify spline count!
- 1 - Reverse rotation Dana 60 front ends with aftermarket ring & pinion sets may require use of the RD166 or RD167. This is determined by the ring and pinion manufacturer. Contact your gear supplier to confirm fitment.
- 2 - Air Locker flange holes must be drilled or reamed to suit 9/16" bolts for Dana 80 applications
