That looks like a 1 1/4" to 1 1/8" adapter shim. If your new stem is 1 1/8" (it looks like it is), you shouldn't need the shim. If after torquing it down to spec as you've installed, you're not able to twist it in either direction, you should be good to go.

The shim is to vary the angle of the stem and is specific to that style of stem.
