I know this has probably been discussed before but I cant find it. Can you convert the gearing in a Bravo X Sweptback to Bravo XRs? I appears that the cases and top caps are the same on both its just the gears and the shafts. Is there anything else other then a normal gear swap to this? Thanks in advance.

Different upper gear set and larger prop shaft and prop carrier

it's just the upper and lower gear sets, the prop shaft and bearing carrier, rear bearing and prop shaft seals.

IMO if your not breaking the X, I wouldn't switch
