well im new too rebuilding shocks, but i finally got the rebuild kit for my monarch i only need the adapter for the nitrogen valve. anywho i am wondering it calls for 2.5 wt oil could i put a thicker oil in say 5 wt and if so what kind of difference in action will that cause in the shock. anybody that could help educate me here would be great. Thanks in advance also one other question anybody that could help me here there are two air valves the one on top that you pump up and the one on the bottom of the piston that is charged with nitrogen from the factory. sram says that when rebuilding the shock you need a special nitrogen valve adapter but that after the rebuild you can just pump that up with air instead of nitrogen. does anybody here know if that being filled with air instead of nitrogen will cause any noticable diff in rebound or compression at all? thanks again

Right off the bat you would be altering the compression and rebound, and the compression curve.

The range of adjustment would move (i.e. you will not be able to have as quick a rebound as before etc.).

Usually you can compensate for thicker oil with the adjuster, but bear in mind that the damper may not be built (ports and so on) for a heavier fluid.

Then there is the aspect of the fluids being marked with different viscosity labels but being close to one another. A Redline oil marked 5wt and Rockshox oil marked 5wt may differ a whole lot.

Are you lacking the correct oil or just looking for a change?

well i am just wanting too be educated a bit i wasnt sure what the difference would be. i have not purchased oil too replace the old yet im sure i can get the type rock shox calls for which is 2.5 wt for the monarch 4.2. I was asking just for information sake so i thank you for your response especially about other types of oil being diff because i was thinking of just going too a cycle shop too purchase the oil but i guess i just get sram pitstop too make sure its what i need for sure.

I'm not completely sure on the nitrogen, I know it helps keep from corrosion, it also keeps a steady pressure under varying temperatures. If you swap w/ air, when the shock internals face temperature change during use, the amount of space occupied by that gas will change. I'm sure this could cause a dynamic change in dampening. Just my thoughts, hope it helps.
-I'm sure someone has to be able to refill that for you, maybe a motorcycle shop that works on race suspension set-ups.
