Title pretty much says what I am asking.

My understanding is that Shimano mtb rear derailleurs for 8 and 9 speeds have the same cable pull ratios so your components should be compatible. The XT M-737 came in a short cage and a long cage version...if you have the short cage version you should do a websearch to check if it will work with a 34T cog.

It's a long cage, just did not know if the geometry clears the 34 t sprocket. So I guess the verdict is still out. I guess I can install and see.

According to this, 32 is the max.

I'd go for 34T. Scres the b-tension screw in all the way and test the lowest gear combo (inner chainring and 34T cog). If the RD's upper-pulley bounces on the cog, you can try installing the b-screw backwards so the screw's head hits the hanger.

I ran one on a 34 tooth cassette, no problem. Mine lasted through a couple bikes and thousands of miles.
