450/525s axle splines?

[Polaris 450MXR]

has anyone tried the Honda hubs on the rear axle are the splines the same? I would like to widen my quad without a great expense and want them to hold up in MX. My honda hubs were always bullet proof. I no longer have my honda and before i buy some hubs on ebay i was hoping someone else had the same idea and has done this mod?

I'm not real sure if they will or not, I bought the Rath Racing MX rear hubs for mine, and they have takin quite a pounding and no signs of it so far
