Talk to these guys:Kenrow said:Anyone know what size the orginal rear shock was for a 2005 NRS was? How about recomendations for a replacement?
I believe the custom Float R on the NRS has a fixed pressure in the negative air chamber.KingclanW said:A word of caution though, 3 years ago sent my Fox Float R off of my NRS to PUSH industries for a rebuild. There was some confusion and delay in getting it turned due to the internals of the shock being slightly different. I don't recall exactly what the issue was but it would be worth some looking into before you purchase a new shock. Believe it had something to do with the zero sag setup of the NRS.
