I still am looking for help with speedo gears. I need to know what color driven gear to run with a 3:73 axle 2.25 x R15 tires and a 4 speed. I need to get the speedo at least in the ball park.

I'm still searching for someone to give me the right answer for my 700r4 with 3.54 gears. I have a large red and small grey but they are still off about 5mph at 45mph, and I think it climbs higher the faster you go.

Here's a link to a calculator if it will help, at least you can watch your rpm's and have a good guess-timate of your correct speed.
