I do not own the truck.......I want to know what 27 axle code is in gear ratio.

obusnizzle

3.73 maybe?

Ty

well, going from those numbers, and how they progress, I would have to say its bigger than 4.10

i would doubt a 4.30 rear gear would have been used on a 1/2 ton application.

Ty

I am just going off of the info posted above, the axle code numbers get bigger with the ratio numbers, so 27, which is bigger than 25 (did I have to say that lol) would have a larger ratio (or smaller, I have been reading all night, and math is not high on my list of things that I care about right now...)

Im not sure, just throwing in my .01 (yall dont even get 2...)

TN Jim

My 07 has a 3.73. If I get time I'll see what my differential has on it in the morning & get back to ya.

Ty

yours is a different body style, are the codes the same?
