I just did a 2" shackle drop in rear and has slight vibration without load when trailer hocked up vibration is greater what size shim should be used thank you

 

I just happen to have a Ground Force shackle kit waiting on install and it has shims. I'll measure them and post up a pic for you. Gimme a few minutes.

 

Ok, here ya go. I got a close up of the numbers on the shims. You might be able to find them online with that if you want. I measured both ears of the thick end and one was .303 and the other was .300. Hope this helps.
