Thanks for the info, but my original gear is shredded, so I can't apply the equation. Do any of you guys have some experience to share as far as which gear to use for 4.10 and 33's w/an AX-15?
TIA
... generally if you have a counter-guy look-up the gear you need for your "stock" application, the last 2-digits are the tooth count -- similarly if you want a 33 tooth - you can have the guy look-up the OEM number then substitute the "33" in to get the gorrect gear....
