gear swap calculator needed.
I'm thinking about changing the gears in my rear end. Does anyone know of a calculator that I can use to guestimate my engine RPM and freeway speeds?

Re: gear swap calculator needed.
This one I like and use a lot.http://www.grimmjeeper.com/gears.html
It is for 4 wheel drive but you can put in any transfercase and just look at the high range numbers for 2 wheel drive. You can put in your current set up and what you want to change to and it shows you both so you can do a side by side comparison. it also has most transmissions available for automatic gear ratio selection or you can enter your own numbers. It also lets you compare different tire sizes along with gear swaps. Brent |
