OME Dakar 300lb shims?

After installing these I have a shake between 10 to 30mph. I did the carrier drop already. Previously my truck had a 2" block in the rear and when I removed it there was no shim underneath it. What size shim should I order?

Thanks

 

Rule of thumb is 1° per inch of lift

 

Gotcha thanks! Didn't know that. Any brands or links of recommendation?

 

Anyone?

 

Any brand shim is fine. Some shims have hole to use center bolt and others have U cut out to slide in place, but those require an extension collar on centering bolt.

 

I didn’t extend the pin on my leaf pack. Depends on the thickness of the shim. These are 2 degrees (steel). Forget who I got them from.

Edit: Warrior Products 800060 2.5”, 2 degree. They got expensive. They are on Amazon.
