will 450r and/or 400ex a-arm mount on a 300ex?

 

i don't think so

 

are 450r and 400ex a-arms the same, and are the 250r a-arms the same as those also the same?

 

400ex will fit on 300ex... However I dont think the 450's will fit on the 400 or 300... I have a 300ex with a 400ex shock conversion, I got the 400ex a arms on e bay and switched them out... Had to tweak it a little to make it work but its sweet with the 400ex shocks. I think am pretty sure the 450's are wider and wont match up, I will look on my 450r tmrw and let you know for sure.

 

alright, thank you very much. That is the responce i was waiting for!
