Z55 rear air shock good/bad?

[TollKeeper]

Since you bought new, you can sell your old shocks to Arnott. They pay 50 each, and shipping.

I don’t remember if it was covered earlier in the thread but make sure you can hear the compressor running after you turn the ignition on. Sometimes when the bags blow the compressor will run until it quits.

The compressor turns on after about 10 seconds of the ignition on, then shuts off and vents. I guess if the truck is level even with the bad shocks the computer thinks all is well.

Then you should be good there. You are correct, it does think all is well if the truck is level.

Just measure the distances from the ground to the top of the wheel well at all 4 tires, to ensure that all 4 corners are about the same height.

Any suggestions?...The air port came off the old shock and the line won't come out of the port...

I managed to disconnect the hose at the compressor. I then put the end with the broken port in boiling water for a few minutes and was able to pull the port off the hose. The hose is clogged though. I tried running fishing line through it and couldn't get it to go more than 1/4" into the hose(both ends). Also the compressor is spitting out rust water when it kicks on now. So...I don't have high hopes for the compressor or the air lines.

You need kit 88987900
If you are getting a new compressor and Arnott shocks you need it anyway. Get the GM kit not the Dorman kit.

That sucks but good thing you noticed before you replaced the shocks!

Replace the compressor and air lines, and you'll be back in business.
