according to rocky mountain atv, who sales the tusk/g-force axle, only the banshee and blaster share the same part #,
the 660/700 raptors and yfz's have their own part #'s.
they do not even list a tusk for a rappy 250 ?
based on that i'm going to say no it will not fit .
same with the dura blue axles rmatv sales...only the blaster/banshee share the same part #
