Thanks for contacting us! We can replace this hardware, yes. I'm told by my colleague Manuella that you've identified this spring as our Series 190 (and I agree), but that yours is stamped with "9."

This indicates 9 pounds of support on each side, for a sash weighing 18 pounds. I'm afraid we don't have a spring that strong, though. The closest solution we can recommend is using a 4 pound S190-440 and 5 pound S190-540 on each side. This should work just as well, but you may need a new detent clip for a double-spring setup. See our 15-181 clip and 15-182 barrel.
