My 93 k3500 454 dually had 4.10's. There's a decal in the glovebox with a bunch of 3-letter codes on it. One of them will tell you. I'd be happy to check Alldata at work to decipher the code for you......

hope this helps.
IN YOUR GLOVE BOX THERE ARE CODES GM USE'S.
TO FIND OUT WHAT GEAR RATIO YOU HAVE HERE THEY ARE: GU4 IS 3.08 .... GU6 IS 3.42 .... GT4 IS 3.73 AND GT5 IS 4.10 THESE ARE THE GEARS THAT COME IN 81-04 FACTORY AND IF THERE IS A G80 BY THOSE CODES ITS POSI.

I hope you bet Bowhay money on that gear ratio , you would have took it , never seen a 3/4 or 1 ton truck with a 270 ratio , he must have had his thinking cap on backwards that day :lol:
just ribbing you Bowhay

I also own a 93 Chevy 3500, it has 4.10 gears and as far as i know they never came with a posi. unless it was a special order, like a 4 wl drive.

Zip.
