On a 2004 Polaris 90. Won't rebound, has an air port, does this get filled with nitrogen or air? No leaks leading me to believe the seals are good. Any suggestions?

The shaft should rebound without any spring or external force required if it is a pressurized shock and is properly pressurized. If it has a schrader valve, I'd expect that it is a pressurized shock (like 250R, 200X, 350X) but I don't know your specific shock, so don't just take my word for it. If it definitely is a pressurized shock, you're supposed to use nitrogen, although I've seen threads on-line that debate if this is absolutely necessary. I'm in the "only use nitrogen" camp on this subject.
Shops that offer shock service don't typically charge too much to charge a shock ($10-$20).

It should have "dry" nitogen if it does not use a badder because the dry nitrogen is claimed to not mix (aerate) with the shock fluid like air can, but pressurizing the shock has almost nothing to do with rebound. In other words, if the shock shaft is stuck partially down and it has a spring on it, it has bigger problems than no air, but you can temporarily pressurize it with air to anywhere from 50 to 100 psi and see what happens, you can also put the shock in a tub once it is pressurized and look for bubbles if it is leaking.Originally Posted by DAM shop
