More importantly, do the splines match? Yes, at least on 03-04 Raptor 660s. This is easy to check because most companies (like G-Force) sell the same wide axle for early Raptors and late-model Blasters. There are some difference to early Blaster axles (brakes and ring gear) but the axle splines are the same.
And like Ride was pointng out, you will need different wheels.
