I found an ARB air compressor and wire harness, and switches, blue lines, electric solenoids, basically everything to operate a set of 2 ARB air lockers LESS the lockers on CL for $100.
I bought it.
Those solenoids are $65 each new. The pressure switch is $20. The compressor new is $170.
Been kinda looking for a compressor to operate the lockers without firing up the big belt driven just for a quick diff lock.
I am pleased. Doubt I will use the ARB wire harness as this requires the rear locker to be on before the front one can be engaged, which makes sense, but there may be some time when I want the front locked and the rear open. And I'll keep the switches and switch mount I have now. And I do not need blue lines. And my electric solenoids are working fine.
but other than that...it was still a good deal.
