I just checked the parts book and they have different part numbers. I know the CVO shocks will have different number because they are chrome, but even the 05 & 06 CVO have different part numbers. That leads me to believe that with the change to the 240 in 06 that they changed the shocks. I could be wrong, but here's the part numbers just in case.
03A- 54582-01
05 CVO- 52558-05
06 CVO- 54743-06
