How to find truck gear ratio
I have a 1980 chevy PU 1ton 4x4 dually and i am trying to figure out the gear ratio. There are no numbers I can find. I dont want to count the teeth on gears. Does anyone have an idea what the ratio might be
Re: How to find truck gear ratio
Your truck was available with about 5 different gear ratios, so there is NO guessing that's going to help you. If you don't have any documentation with the options for the truck, you're basically going to be left having the count the teeth on the ring and pinion.
If you choose to do that...count the teeth on both the ring and pinion gears and then divide the pinion number in the ring gear number to get your ratio.
For example: Pinion teeth = 11 Ring Gear teeth = 45 would be 45 divided by 11 = 4.09 gear ratio (would round up to a 4.10)
