Noisy leaf springs after airbag install

[Jacob D]

I have a new 2021 Sierra 1500 3.0L that did not have the max trailering package. I was disappointed in the suspension and decided to add airlift 5000 airbags. Once they were installed I noticed something very noisy when going at slow speeds and making turns or any point where one side of the rear was at higher ground than the other.

 

I narrowed them down to the leaf springs when they slide side to side. It appears the rubber or whatever that thing is between them makes a TON of noise. I decided to try to clamo them down as hard and possible and the noise died down a lot but not completely (couldn't prevent them from moving totally)

 

How can I fix this? I didn't notice it before the air bags so my assumption is the bags took weight off the springs and that's the issue

That noise is a royal PITA, but fortunately easy and cheap to fix.  See attached, specifically page 7ish.

Why not deflate the airbags when your not towing?

Even with the bags deflated it still does it, however they recommend to always keep at least 5psi in the bags. I kind of wonder if it would of started doing this with or without the air bags. The above post just makes me thing it would of came up either way.

Thanks! I went ahead and ordered the spring-things kit since it wasn't much. I don't have much faith in GM at the moment. New $50k truck and already had starting issues (3.0L), power steeling didn't work twice when starting, noisy leaf springs, disappointed in the suspension and whatever else I'm forgetting to complain about lol. They need to start implementing return policies if they can't keep their QA on par

I got the spring things installed and it was instantly better. I only did the forward on each spring. Come on GM!
