Putting 400ex LSR axle on my 450er

[yamablaster24]

Hey guys i got this LSR axle-antifade setup from my brothers 400 and i need to know what i need to do to put it on mine. Is it worth it? I need to know what needs to be machined off. From what i heard the sprocket side needs to be machined off and a spacer made for the brake rotor side. I am going to have a machine shop do the work just need the mesurements. Please and thank you

come on guys, i have read you needed a 400ex carrier, or some have been able to put a 1/8" spacer..... anyone?

i thought that a while back i heard on here that if you have a 400ex axle and a 400ex carrier it should work in a 450r

I dont think Im really helping you much but I bought a RPM axle for my 400 and they sent me a 450r and it wouldnt fit at all on my 400 because of the sprocket hub. The sprocket hubs are completely different. If you call Lonestar I'm sure they'll tell you how to make it work.
