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. ARB onboard air compressor required to activate Air Lockers. Sold Separately.
The ARB is the best of the best selectable locker out there. You really do get what you pay for. The only draw backs are the cost and the installation, I would not recommend a beginner even try and intsall one. You also need to have and maintain an air source on your vehicle, but that can be a pro as you will now have on board air for other things.
But the ARB is really in a class by itself based on quality and reliability.

arb air locker
had an issue when in deep snow and ice, first time out, the ice was crushing against the skid plate up against the line, causing a tear in the air line, then loosing both and getting hung real good....but other than that they have worked flawlessly so far.
Will this work in my 2004 ram 1500 5.7L front axle? Currently I have 3.55 gears, and am converting to 4.10 gears and would like to have a selectable locker in the front end to go with a Detroit locker for the 9.25" rear.

have a 1978 ford f-150 high pinion dana 44. will the OE carrier bearings work with the ARB carrier? going to be running 5.13 gears..
Rob from Portland Or. on
The ARB does take larger bearings than stock which come with the unit. So you will get the bearing and shims in the box with the locker.
