Are fox & rock shox rear shock mounts compatible with one another?
(i.e. An old fox dhx4.0 & monarch rt3)

If you are referring to mounting hardware then yes.

Yeah, the hardware. I'm swapping shocks so just wondered if I needed new mount kits!? Glad I don't as one of mine is a bloody awkward size!

Same nominal size, but the tolerances vary. RS eyelets are usually on the small side and Fox on the big side.

So Fox hardware in a RS shock would likely be hammer-fit (tm) and RS hardware in a Fox shock would likely be loose enough to knock.
