Gear ratio calculator online?

20 years ago
Hi all,
Sorry about the semi-crosspost, but I figured these 4 NG's would be my best bet for a quick answer on this one. I remember seeing a gear ratio calculator somewhere on the net. Does anyone have this bookmarked or know where it is?
The one I remember had fields for engine RPM, tranny ratio, transfer case ratio and axle ratios, giving you your final speed at any given engine RPM. I'm considering using the stock axles in the FrankenWillys
Thanks in advance for any help.
Cheers, - Jeff G

One calculator is at
Note that the high gear in most transmissions is 1:1, so the RPM you're losing is likely in the axles. That was the reason for overdrive: make the driveshaft turn faster than the engine, to make up for the reduction in the rear axle.
Good luck!

Thanks Jim, I downloaded it. Just an FYI: the link on your page isn't correct, but I made an educated guess and guessed right.
Your link on your page is:
