Apparently you can also figure out the ratio by getting the rear tires off the ground and turning them one complete revolution. The number of turns the axle makes is the gear ratio. Sounds like a lot of work, though.

My old van has a 727 tranny and 9.25" rearend. According to the paper inside the hood it has 3.21 gears. Don't know if this tells you anything. Its a 1976 B200 Maxivan.

Jack up your rearend. You have a locker?? Jack up both tires. Put the tranny in neutral(block the wheels!!)Mark the driveshaft with a marker or chalk. Turn the tires by hand one full rev. Count how many turns the driveshaft makes. This is your :1 ratio.I.E. 3.55 turns would be 3.55:1. The more turns the lower your gearing.

Damn, you should be on the poetry site not BC4X4! Seriously tho it is pretty easy. There are formulas and charts for RPM etc. but exact tire size makes a big difference. Numbers can get confusing. Counting driveshaft turns is a lot less brain cramping.

I would count the drive shaft turns, but my truck is surrounded by 2 feet of snow that was left by the plow.


Nobody knows what the stock gearing is for a 74 Dodge Power Wagon?

I gusee it will have to wait until the snow melts
