Aftermarket Shock internals?

[trek]

So I was taking apart my shocks to get ready for a rebuild and found some aftermarket parts. I then realized I had some matching parts in my toolbox. Anyone know who made these or what they were called? I do know that they set up a variable valve hole that gets smaller as the shock compresses. I also found some seals at the top that look like they would keep air from mixing in the oil (since there would be an air pocket at the top of the shock from cap). Amazing how your memory forgets about things..... Funny thing is the front shocks didn't have the variable valve and I don't seem to have the tapered piece for them anymore (if there ever was one). Now I wonder why.....

those black things might be CRP shock pressure gaskets

That looks like them. Thanks for that AndrewSi, I had no idea what they would have been called.
