Re: Rear Axle Ratio Charts For 1967 - 1972 GM Trucks
-
This is the last Chart. It looks like they are mostly readable. A couple of them may be a little blurry.
There is no guarantee of correctness or completeness (is that a word?) in any of these charts
Edit: I might as well add this chart to the thread too.
Rear Axle Ratios
Ratio 2.56:1 - Tooth Combination 41,16
Ratio 2.73:1 - Tooth Combination 41,15
Ratio 3.07:1 - Tooth Combination 43,14
Ratio 3.08:1 - Tooth Combination 40,13
Ratio 3.08:1 - Tooth Combination 37,12
Ratio 3.31:1 - Tooth Combination 43,13
Ratio 3.36:1 - Tooth Combination 37,11
Ratio 3.42:1 - Tooth Combination 41,12
Ratio 3.55:1 - Tooth Combination 39,11
Ratio 3.73:1 - Tooth Combination 41,11
Ratio 4.10:1 - Tooth Combination 41,10
Ratio 4.11:1 - Tooth Combination 37,9
Ratio 5.14:1 - Tooth Combination 36,7
The tooth combination numbers will be found stamped into the ring gear when you take the back cover off.
They may not all be for the trucks.
