Identify Your Ford Truck Axle From The Door Sticker

There’s no question, the easiest way to identify the axle and gear ratio in your truck is from the door sticker. If you open the drivers door and look at the door jamb, you’ll see a sticker like the one shown below:

You’ll see that the area labeled (F) is for the Axle Code.

Here are some examples of actually stickers:

Once you know the door code, go to the chart below to identify it. If for some reason you find a code missing from the chart and would like to add it, please use the Contact Page.

You’ll notice that there are some codes with different gear ratio’s listed. Unfortunately, the same codes were reused in different years. If you have any more information to help narrow these codes down, please use the Contact Page.
