Is there anywhere I can look up my vin # and it tell me all the details of my truck? For example the gearing in the rear end.

 

that should be on the sticker on the drivers door jam

 

Check the sticker on your door and check it against these codes:

18 - 3.08 Open
27 - 3.31 Open
19 - 3.55 Open
H9 - 3.55 Limited Slip
26 - 3.73 Open
B6 - 3.73 Limited Slip
25 - 4.10 Open
B5 - 4.10 Limited Slip

 

Thanks guys. I have the 3.73 Limited Slip.

 

Ah, that means I've got 3.55 opens.

 

You have two or three choices:

The vin number is on the man'ft sticker on the inside of the driver's side door.

The vin number should be in your manual.

The vin number can also be found in front of the windshield in front of the windshield on the driver's side. It's a grey stamped piece of plastic or metal..

Hope this helps.
