XZ has a helical cut fine tooth upper. XR has a coarse square cut gear.

Also XR gears are net forged to handle more power and XZ gears are near net forged. If you have over 600 hp, I would suggest going with XR gears only.

I was told that Merc had discontinued the regular Bravo upper gears and that now when you order a gearset from them, the XZ gear is what you get. Can anyone verify this?
