VIN# decoder


Recommended Posts

I just purchased a 2016 GMC Sierra and would like to know how to decode GM vin numbers to determine specifically the rear end ratio in this truck. Also is there a website where I might be able to find an original sticker or a list of installed options. Thank you for any help.



Email gm customer service. They will provide you the build sheet. I did it with my Tahoe

The RPO codes are in the upper glove box.

 

Then find the RPO code for the gears and that will tell you.

GU6 is 3.42's

GU5 is 3.23's

GT4 is 3.73's.

 

Those are most common gear ratio's on a half ton.

Unfortunately socialmedia won’t provide this service anymore. Couple guys tried here not to long ago they just send back a generic email stating they don’t.

 

If the guy at the parts counter at your local GM stealership is cool they can print a copy of the build sheet out for you. Also the sales department can order a copy of the window sticker for a cost. 

 

Otherwise you can buy a replacement window sticker from a site like this.

I just went to the Chevrolet web site within the last month and did an on line chat. There was an option to save the chat via email. I asked them to provide me the build info on my 2016 and they did it. By saving a copy of the chat, the build info was then in my email inbox.

There's also a pretty good resource for this kind of info located at (WWW.decodethis.com). You get basic info for free and more detailed stuff for a small fee. Check it out .......... it ain't bad.

 

Regards,

Joe
