What are these?

[ChelleRee82]

Now what are these? They came in a tool box with a MAC air chisel. They are gradually wider 2-1/4"diam to 2-1/2"diam on open end. And all about 2-1/4" high. The pounded ends are all about 1-1/8"diam.
Please share your great wisdom with me. Thanks

Rivet setter?

Looks like they're used to press in seals.

Bushing driver adapters. Should be a shank to fit the air hammer and then the adapter is used to drive front end control arm bushings in.

they are bushing drivers/installers. usually you just smack them with a hammer. very handy don't think they even make them anymore.

Yes..they are bushing knockers...looks like you got the complete 4 piece set.

Bushing knockers
You can use the blunt hammer chisel in the set to pound against these
