450r locknut and hub on 400ex?

[joeb2300]

Does anyone know if a lone star 450r locknut and brake hub will work on a 400ex axle?

It will work on the axle but not the brake rotor. The 400 rotor is 4 bolts and larger in diameter, the 450 is 3 bolts and smaller...

You can use the hub and add the 450 brake stay, caliper and rotor for a nice up grade.

I plan on using the 450r brake rotor and hub with the nut so I can upgrade to 450r brakes
