Can I use an ARB compressor to power factory Rubicon lockers?

[Danthejeepman]

My 2004 Jeep tj rubicon was missing both air locker pumps when I bought it, and people suggested some Kia pumps that are the same things as cheaper replacements. I was wondering if I could use a arb compressor to air up and use their air locker kit to use on my factory air lockers

Some people have, but you have to regulate it down to like 5-6 psi to run the lockers. The factory lockers run real low pressure. Have you pulled the diff covers to verify the stock lockers are still installed, and intact?

I too would suggest pulling the covers to verify the lockers even exist. The lack of both compressors is a bit worrying. Besides, it's always prudent to check the condition of the diff components on a new-to-you Jeep

And welcome to the forum!

How do you know the compressors are missing? Where did you look or did the previous owner tell you that?

This is a good question. It's not uncommon to relocated the locker pumps. Mine were moved into the engine bay.

The guidance on the ARB compressor is correct. I don't even know how many psi mine puts out but if I hooked it directly to the stock lockers something would blow out.

If my pumps ever go out and I can’t find a suitable replacement, I’ll likely try these down to 5psi: https://www.amazon.com/dp/B00042JHT4/?tag=wranglerorg-20

But as others said, trace the air line to see if they were moved.
