The autoride air package is all new. Nothing changed with it's install. I askthe same question.

This is a coil sprung suspension so no leaf fix will work for this tahoe.
But I will have him try some of the coil ideas. I think the best thing would be to swap springs from left to right. If the lean is still there then there is more going on than springs. I will try the body and frame measurements also.

Oh yea forgot about it being coil springs on the rear. Sounds like a plan swapping sides. I second measuring at the frame too. For whatever reason my left rear fender height measures 1/2 inch lower than the right rear but measuring off the frame the truck is perfectly level side to side. Nothing is bent, out of shape, damaged, or even looks like its off, but measuring it by the fenders something is up with the left rear bed side yet the fit and finish is still perfect. Its weird but go off the frame and you should be good.

Being an suv with the 4 link rear, that isnt an option for you. I would just google like a **** lol, for someone who has fixed this issue.


I read somewhere about someone that was working for GM to straighten out frames bc when the trucks are shipped they are strapped down in the rear only on the drivers side and they have the lean from the get-go because of this. Not sure on that thought.
Do you have the part numbers for the items you bought from gmparts?

My 04 had a 1" lean when I bought it. The previous owner had taken the passenger side overload out to level it. Talk about some terrible axle hop!! I had a spare overload I put in it thats when I noticed it lean. I just finished installing a 3-5 drop on it now the lean is gone. Still have both overloads in didnt shim anything either. bugged the crap out of me at first!
