will the 450r rear shock fit on a 400ex. i know the fronts do and i dont want to spend 600 for a damn rear when i dont need one that fancy.

 

Yes they do. I have one on my 400. I had to adjust it quite a bit. It packed alot on the whoops, so I had to adjust the rebound a lot. It bolted right up. SOme people say you have to make som mods, but I did not..Check e-bay for a rear shock.
