Or are the codes the same?
Codes might change but ID tags on rearends don't use a code to state the gear ratio they simply stamp the ratio. If it says 2.80 8 it is an 8" ring gear with a ratio of 2.80:1....2.80 9 would be a 9" ring gear with 2.80:1 gear ratio etc. This nomenclature was used for decades and never changed with removable carrier type rearends. If it had been 2L80 8 it would have been an 8" ring gear with a 2.80:1 gear ratio with a locking carrier (posi).Ozsum2 said:I have found that codes change from year to year. If you would like, I can tell you how to find the ratio.

And you said you could help him find the ratio if he liked and I was simply pointing out that there are no codes to decipher in order to determine gear ratio as listed on the tag. I just thought your reply was a little unclear and implied that the codes had something to do with the gear ratio when they do not. It's all good!Ozsum2 said:Thanks, but I was commenting on codes.
