I ended up ordering new OEM air shocks from rockauto just like I did for Denali #1 last month. I also swapped out the compressor with a new Dorman unit. Got it all installed this evening in a couple of hours and everything seems to be working great. Air bags are plumped up and holding air. I’ll be hooking up the camper for the weekend tomorrow so I’ll see how she does on the trip and report back.

Confirmed that the problem is solved. No sagging after a couple of hours on the road tonight.

Awesome, glad you got it fixed. So many people think these systems are complicated or too expensive to repair and get rid of them but it’s nice to have the self leveling when towing or hauling a heavy load.

I agree. It’s a great system and awesome for towing. Easy to work on as well.

And there are others that are forced to get rid of the ALC shocks in the pursuit of moar lowz but still realize the value of it and try to Frankenstein alternate solutions. Those people are stubborn and gluttonous idiots.


BTW, I'm still not quite finished experimenting with mine yet.

One more thing I noticed about the new rear suspension components, is that they don’t sag even after the truck has been sitting for a couple of hours with a trailer attached. It’s a good sign that the system is on the way out, in hindsight, when the rear end squats after a little while due to slow leaks. My guess is that those leaks compound while the suspension is in motion during travel, and eventually overwhelm the compressor.

Did you try to command the new pump on with the tech2? I had a faulty ride height sensor in the rear, replaced and all senors seem to be within voltage, but i can’t make the pump come on with the trch2, but the pump will run with key on and air up as needed. The release solenoid I can hear click but don’t hear any air escaping. Is that normal?

I wasn't able to command the old pump to come on with the Tech2, but haven't tried it with the new one yet. If I get a moment today, I will go out and try it again now that the new pump is installed and working great.

Just curious - how did you determine one of your ride height sensors was bad? Was one of them outside of the normal voltage range?

I think you'll be happy that you got OEM components over the aftermarket "rebuilt" units. The extra money is worth the peace of mind in my opinion.
