A project I'm working on involves a 2.75"OD shaft with some rings/bushings that are a slip fit over the shaft but are 3"OD. I need to reduce the side friction of the bushings so they can twist freely. Is there any kind of a bearing that I could slip on between bushings like a washer that would allow them to roll around freely? I'm looking for something as thin as possible, around .125" or less.

If I'm reading you right, you're looking for some type of thrust bearing. You can go with needle caged rollers or probably much cheaper with some bronze/oilite types. Either one could easily be under 1/8" thick. Here's an example with only a 2"ID (they're not exactly giving these away, are they?)

BTW, I checked out your project pics and I like the style of your machinists jacks. Have fun! Sidegrinder

Check with a auto transmission repair facility. the transmissions use a lot of thrust bearings mostli about 1/8 inch thick.

Again, only 2" i.d. maximum, but you may be able to find larger elsewhere. See "Thrust Bearing" at www.mcmaster.com

McMaster also sells Bearing grade bronze sheets, you can cut your own out if you can't find what you need.
