Stratmosphere was a dealer of ours prior to releasing their valves and by some coincidence the internals of our valves will work in theirs...

Not sure about the springs but from what I've read on this forum you will need something that is pretty stiff. If it turns out that it doesnt have them you can order one of our spring tuning kits.
