Just curious what's the web site where I can match up the numbers. I know wiht the 2wd I do not have 3.73's.

I am wanting to re gear the rear and put in a loc rite I am pretty sure that going from my little gear and going up will wake it up especially custom dyno tune this summer

You can figure out by looking the axle code what is in your rear differential.

 

The axle ratio is *NOT* in the VIN, it's only on the door sticker and axle tag.

 

That site does not decode your VIN, it shows your window sticker with all it's options.
