yes they will work. you just need to transfer over your nitro weights, springs and the helix.
using a vector primary one one sled and a viper one on another as i cracked the clutch faces.

Secondary wont switch over. I think the shaft is splined on the Viper. Correct me if I am wrong.

from what i have read on here, the nitro, viper and sidewinder all share the same size secondary shaft and spline as there was guys looking at the sidewinder roller secondary for their viper/nitros from what i remeber.

Correct, as long as the Nytro is 08 or newer(FX). The 06-07 old style Nytro has smaller shaft, same as Apex.
