So I was curuous what ratio I had in my truck and I looked and there isnt a tag on the diff or in the glove box. I remeber reading on hear about getting a build sheet. I searched but couldnt find out how to order 1. Anyone know how to order 1?

 

Here ya go.

Build sheet

Here is an instant VIN decoder, it will work with any make/model. It will tell you what gears that you have.

3.55 is the most common, 3.92 if the original owner was looking for towing.

 

Thanks!
