Re: rear end [In reply to] Sign In

you have a few options.

1. write down the last 8 digits of your VIN and call the parts department of your local Chevy dealer. They can look it up.

2. look for a steel tag mounted either on the axle tube or the diff carrier specifying the model number, serial number and ratio of your axle.

3. take off the diff cover and count the number of teeth of the ring gear and the pinion gear. Divide count of the ring by the pinion and that is your ratio.

Let me add a 4th possibility...........

You first need to know if it's limited slip or not.

Jack it up to get both rear wheels off the ground

with limited slip....
mark the bottom of the tire with a crayon. Now rotate the driveshaft, counting the exact number of turns to bring that mark one revolution and back to the bottom.

without limited slip
Mark one of the tires the same way but someone is going to have to hold the other tire still and this time you would rotate 2 full turns until the mark comes back the second time.


Once you have done this, analyze the number of turns of the driveshaft. re: 3 1/4 turns would be approx 3:23, 3:25 etc. 3.5 turns would be around 3:55s, Just over 4 would be 4;10, 4:11, etc. You would first need to know what your choices are.

I hadn't even thought of limited slip. My brain must be taking a weekend off. Thanks HT.

Nick and HT . It does the heart good to hear knowledgeable techs answer a technical question .I would like to add , to determine whether you have posi/limited slip or an open rear end . Whilst you have the rear wheels off ground , rotate one wheel. If the other wheel turns the same direction you have a posi /Ls .If it turns opposite you have an open rear end.

The first three digits stamped on the right side axle tube is the gear ratio. There is also a sticker in the glove box called the RPO sticker. It has a bunch of letters and numbers on it.

GT4: 3.73:1
GHO: 3.54:1
GT5: 4.10:1
GU4: 3.08:1
GU6: 3.42:1
HC4: 4.65:1
