Axle gear ratio

[duramaxdude]

I am curious what my gear ratio is on my truck. I have a 1995 chevy Silverado 6lug 3/4 4x4. Just thought somebody might no. I think there is a certain code to look for in the glove box but I have no idea what to look for. If it helps I run at about 2100 rpm at 100km/h with stock 16in tires.

I've never used this but it may help: http://www.c2e.info/rpocodes/

From what you said I would guess you have 3.73 gears

Type your vin into this http://www.compnine.com/vid.php It will tell you everything about it as far as how it came from the factory.

if you suspect the axle might not be original a simple thing to do is jack up one back tire, make a mark on the driveline, then rotate the tire one revolution and count the number of times the driveline turns. If it goes 4 plus a little in rotation then it's 4.10's. Not quite 4 would be 3.73. It's most likely one of those ratios.

Mine is a 1995 K2500 LD (6-lugs) and got the 3.42 gears.

RPO GU4 -> 3.08 (only 2WD)
RPO GU6 -> 3.42
RPO GT4 -> 3.73
RPO GT5 -> 4.10

I looked It up and I have 3.73 Poisitrac. I was pretty sure it was 3.73 but wanted to be sure. I didnt expect the Posi though and I am pretty sure it was never chamged. Thanks for your help everyone.
