I have an 03 400ex and the front shocks are shot. My fourwheeler is alot lower than its supposed to be just because the shocks are getting so crappy. I want better shocks, so I was looking for some on ebay and I didn't know if 450r shocks would fit? I was looking at them because i know they would be better than regular 400ex shocks. I didn't know if my atv would sit weird or anything? And how do I know if i need a new rear shock? It seems fine but I just wondered.
