Yes they will work together. I know they will mount up with 6 inch width and think they will also mount up with both 5.5 and 6.5 width. You didn't mention the load range but if it's c or d there shouldn't be an issue. Keep in mind that d range are usually filled to 65 PSI and that's the max for standard valve stems so you might want to go with a higher pressure stem.

I actually have load range D. I never thought of the stem, good tip and looks like I should be ok according to your post.
