Help me identify this part

[Third Coast RC]

Has anyone seen one of these:

It's 39t, it came out of the 2 speed trans and is part of the 2speed gears. I can only find them in 37, 38 & 40. Does anyone have any ideas?
Thanks,
Justin

thanks double G, my owners manual has the standard gear ratio as 17/37, not 17/39.

Must be a misprint; the Revo manual is correct. Standard is between the close and wide gear ratios. Clicking on the numbers on the exploded views of the Slayer and Revo pulls up the description.
