gear ratio

does anybody know what gear ratio came in the 95 S10 2dr blazers 4.3L vortec 4x4 I looked at the axle tube it had
C 052 1 that was all I saw. Should I just due the lift and spin. I didn't see any other numbers, or tags.

Re: gear ratio

I would say that it is a 3.43 rear end.

Re: gear ratio

check the inside of the glove compartment for the RPO plaque. It'll have a bunch of 3 character codes, and you can run 'em through the code generator at s-series.org. It's more than likely a 3.42

Re: gear ratio

she bought it used. Must be a Canadian thing, cause damn near every S10 I've crossed paths with has a posi. She's got the SLE package, I think. If I make it home before she takes it out camping (she's towing the boat, dad's towing the trailer behind his Sierra) i'll take a look. she's got air, tinted windows, tilt, cruise, 6 way power adjust driver's seat, no leather... CD & cassette... i'll know more once I get home after work today... the joys of eating lunch at home!
