I was talking to a buddy today about how I plan on getting ARB lockers when i finally upgrade my diffs. His opinion of them was that the Eatons are way better for a few reasons, but his biggest argument was that "the compressor will be running a lot". He said he was in a vehicle that had ARB lockers and an ARB compressor and that every 20 minutes or so the compressor would fire on for a few minutes... and wait 20 minutes... compressor fires up... etc. We discussed it further and I was under the impression that once you engage the Airlocker and it pressurizes it doesn't really lose much air after that. He said though that they are not fully sealed, and they are constantly (or even occasionally) leaking a little bit of air, which is why the Diff needs to be vented. I mentioned that maybe there was just a leak in that paticular setup but he seemed pretty adamant they are all like that.
So how are they on everyones rigs here? Once the compressor fills up the tank and the lockers are engaged, are you good to go? Or is the compressor always turning on intermittently? Any insights would be great. Thanks everyone in advance for your responses!!!
