Great selectable locker for my dana 44 rubicon
This locker is a great build quality, and arb stands behind there products well. I got this to replace my factory rear locker that failed. I will be getting one for the front when that one fails too. It's pretty easy to install if you're mechanical enough.

Air leaked
Liked the idea .I already had a good air source. I installed it myself.and would recommend it only if your mechanicaly inclined. Spreading the axel is nessisary to seat the unit.I did the best I could.first attempt it started to leak air.seemed like other people had a similar problem.second attempt started to fail as well.it was getting a little agrivating and wished I tried to electronic one.third attempt I took off the rear axel plate to see again were it was leaking.it apeared to be the seal for the loker.before I went through all the work to disassemble it while the air was leaking I got a small piece of wood .removed the left bearing cap and tapeped the bearing. The leak stopped and so far no issues.
