Spacer to fix suspension lean?

[Brandino13]

Hey guys,

 

I have 2 main questions I am looking to get answered on my 2003 Chevy Avalanche.

 

Before I put my 2.5" lift blocks in the rear, my rear end wasn't level. For the life of the truck it had a lean. I figured lift blocks would help it, or maybe fix it.

 

Subject Vehicle Lean.......Left Front/Rear Side Low or Right Rear Sits High (Add Spacer Between Left Rear Spring Pack and Axle) #06-03-06-005A - (01/12/2007)

 

Models: 1999 to 2007 ChevroletSilverado (Classic) 1500 (½ Ton) series

 

Models: 1999 to 2007 GMC Sierra (Classic) 1500 (½ Ton) Series

 

After installing the lift kit, it did not fix it, and I still have about a .75-1" sag on my drivers side rear compared to the passenger.

 

*Here are my questions.

1. Would I be safe with putting a half inch spacer between the lift block and the rear axle? If so, where's the best place to buy one (material doesn't matter).

 

2. I would rather not buy a bigger lift block, and I would rather not bring my truck to a shop again to put in on a vehicle lift. If I were to jack up the frame, is it possible to slip in that half inch spacer? I understand I would have to disconnect a few things, I'm just curious if I can install this spacer with a regular car jack.

 

Thank you all, and if you have any ideas or suggestions, I'm all ears. Thanks in advance.

When you measure from the ground to the center of the fender lip on each side, what do you get? It's never a good idea to stack spacers.

 

I can't remember, is that coils or leaf spring rear?

If it has adjustable torsion bars, give it a couple cranks on one side or the other. I had a 99 dakota that leaned really bad because the previous owner was about 300lbs, so he had cranked the passenger torsion bar down so it sat level when he got in.
