Hi
I would like to change my diff., oil however I can not be sure if the diff., is locking or not. My sales sheets and original window sticker from the dealership does indicate a locking G80 diff., associated to the VIN #. However my RPO does not label a G80 at all. I have e-mailed GM with my VIN # to find out and they have not answered back. Is there a way know for sure by just looking at the cover?

Thanks again.

 

Is it the window sticker from the originalChevrolet dealer, or a sticker from a secondary used car dealer. If the latter, don't trust it, because these can beprinted to say whatever they want it to say. If the RPO code sheet inside the glove box door does not say G80, I doubt that you have it. Take the VIN to the parts counter at a Chevy dealer and they can tell you whether it came with it or not.

 

get outside on some snow and punch it

 

The window sticker is from the GM dealer. I bought her brand new. Even the price breakdown has it listed as an extra.
In the snow and mud it feels good and has not problems going through and out of situations.
Is it possible since the RPO has "ZR2" in the list it is assumed to have a G80?

 

If it's a ZR2, it SHOULD have the G80...

Is it a 4x4 ZR2?




Not gonna do anything if both tires are on snow... If both tires have no traction, BOTH are going to spin, even with an open diff.

Put one tire on dry pavement and one on ice and see what happens, lol.

 

was it even possible to have a 2wd zr2? kinda defeats the purpose of the zr2 package i think

 

Yes, it was possible to get the ZR2 package on a 2wd truck!

 

i would say if its not listed then you don't have it, zr2 is the rpo code for the suspension package.


here is a list of all rpo codes for those that need it.

maybe this site should get put into a sticky

You can get 2wd Z71 packages

Some people like the wider stance and extra height of the ZR2... In 2wd you could probably make it a decent pre-runner...

 

GM has just clarified that my 4X4 ZR2 does have a G80.
I then asked them since it is not listed on the RPO how can I be sure, and is it listed anywhere else.
The response I received is :

Do you know of any other indication I could look for without ordering a Vintage Package?

Thanks again.
