Could someone list the amount of teeth on the ring and amount on the pinion for each gear ratio?

I think I landed a geared axle for my swap...

# of teeth on the RING
divided by
# of teeth on the PINION

Stock base 4x4 has 10 teeth on the PINION and 41 teeth on the RING for a 4.10 ratio

(there's one on my desk as a paperweight)

So my setup is definatly 37 and 9 which yields 4.111111 on my calc... Whats up with that.

Thats the most common ratio by quite a bit - would be extremely likely that any axle you find will have that gearing.

This is the correct # of ring & pinion teeth for factory 4.10 gears.

4.11 is slightly lower than 4.10, which to my knowledge is the most common, at least the years I'm most familiar with 86-95. The only other oddball gear set that I have seen was 4.38 which were only used for 1980. Anyway only seen one set of those.

See this site here has the 4.11 like you got. Don't know anything about them. I personally believe that a fewer number of pinion teeth for the same gearing ratio(nearly) is a bad idea. But, I don't have the empirical data to back that up, just a strong line of reason.

82 Trucks used the 4.11 gear ratio. It was also used in some T100 trucks. Less teeth generally means stronger, so 37x9 (4.11) would be slightly stronger than 41x10 (4.10)

I wouldn't suggest mixing the diffs, if they have different ratios, but 4.11 to 4.10 would make a huge diff.

I dont know I'm not using the third just pulled it and the gears are good 20 years later. Thats weird though 82 third in an 84-85 axle...

toyota 8" thirds will fit from 79+, so an 82 diff in a 85 is not that uncommon.

I think I have most of the Toyota ratios listed on the table below:
