This fits perfect on my ZR trem. I got it all together quickly but make sure you have zero tension on strings when adjusting. This means you have to loosen your strings almost entirely when you turn this with an allen wrench. I got mine all back together and strings were fairly loose, snapped on first turn, just like the original. This metal is so cheap and brittle, you can see the porosity on the broken chips, it just crumbles. I don't know why on such an important piece they don't use stainless steel or at least good metal.
As long as you keep lowering the string tension until it spins easily you will be ok, if there is any resistance you need to stop because it will break. I'm finding a lot of bad things about this ZR trem's quality but when it's working, there's nothing better for staying in tune and smooth bends.
Good luck. .
