ARB Air Lockers can instantly lock differentials and allow you to tackle the toughest off-road terrain. The Air Lockers can be installed in both the front and rear axles. The ARB Air Locker is a pneumatic locking differential that uses air to facilitate the locking of both axles. This action converts your differential from a conventional open to a full spool type axle supplying 100% power to both wheels to keep you going through the worst terrain. Your vehicle's standard (or open) differential is designed to allow each wheel to turn independently, thus eliminating binding during turns. While off road this becomes a major burden as engine power will take the path of least resistance, which occurs at the wheels with little or no traction.

An ARB On-Board High Performance 12 Volt Air Compressor - Compact Size, CKSA12, High Volume, CKMA12 OR Twin, CKMTA12 is required for installation.

  • Easy installation
  • Easy, convenient operation
  • Provides 100% traction on demand
  • Ultra durable and extremely strong
  • Thoroughly tested and proven design trusted
  • Vastly improved traction means less reliance on momentum
  • Incredibly simple yet effective design that employs minimal moving parts, thereby ensuring maximum reliability

ARB Locker -- Game Changer

Awesome purchase... Shipping and Delivery was great as always, but I'm submitting this review because of how well the product works!!! Installation: Very straightforward. Take your time and you'll be fine. I did a gear swap and axle-upgrade at the same time. If you are upgrading axles, then remove your ABS rings from your old shafts and transfer them to your new shafts (hammer required, worked front and rear). As a home mechanic, it took me a full day to complete. I was able to get all bearings seated properly by oven-heating them before installation, no press required. This kit comes with replacement carrier bearings and I replaced my pinion bearing as part of the re-gear. Trail Performance: AMAZING. Trails that I had to fight to get up are now trivial. This locker helped completely transform my jeep. No more rock-stacking and 'bumping'. No more taking the bypass.
