I ordered these Maxtrax shock extenders. I think these will help me get the full two inches of lowering.

They only help to keep the shocks from bottoming out. They are definitely recommended when you’re lowered but your ride height sensors are what determines the height of the truck. The suspension computer will see the truck is lower after you install those and add air to bring it up to where it thinks it needs to be. For a passive system the shocks don’t provide any lift so extenders just help to keep shocks from bottoming out but on the auto level systems as you know the air bladders on the shocks do actually lift the truck up. But the extenders don’t change what the ride height sensors see, so they will simulate a load on the rear of the truck and the compressor comes on and raises it up. You can take another 1/4” out of those rods and get about 1/2” of drop iirc.

Ok, going to do that today. Thanks.

Hmm, I did remove another 1/4" or so and now I'm getting "service ride control" message. It seems like it dropped slightly...Any reason why the driver's side is higher than the passenger side?
I think I'm ready to switch to a passive system in the rear. Just wondering if the eibach springs will hold up the rear?

Did you pull an air line and release all the air, then start it up and let it air up? If the sides are at different heights it would be because your height sensor rods are different lengths.

Naw, the rods are the same. It had a slightly different height from side to side before I changed them too. Although I guess it could be improper torsion bar adjustment in the front. I did a little research online and found a YouTube video and disabled the auto ride altogether. I cut the orange wire in back.

Sounds like the good old Chevy lean.

Does pulling the air line release the air? Or is there another step I missed?
You disabled the auto leveling so eventually the air will all leak out but yes you can pull an air line off a shock and all the air from both sides will release. The Chevy lean applies to all the trucks and SUV’s though, with auto level or not. Some say it’s because the fuel tank and driver are on the driver side so they lean that way. It’s usually 1/2-3/4” and there are things you can do to level it out if that’s the case including adding a small spacer or cutting a bit of a coil in the rear and for the NBS, adjusting the torsion bars in the front. Google Chevy lean.
