the 250 axle physically fits the ltr carrier so ill assume that the ltr will fit a 250 carrier but if you notice from the pics the ltr sprocket and brake hubs are further apart since the carrier is wider on the ltr. at zilla thon later this week ill try to measure the distance between the sprocket and brake disc themselves. even though the ltr carrier is wider the hubs are not flush and slide into the carrier so it my be more useful info for someone contemplating a swap. if i can find a 250 carrier ill try to get a pic of it with an ltr axle in it.
