Rear Spacer Lift

I just got in a 2" rear spacer lift. (eBay Special) It came with 2 metal washer or bushing type things. Anyone have any idea what they are for?
Thanks

Trash can. Don't need them just toss it

Thanks.
Ya, I figured they were universal, so may be necessary in some other applications.
