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 ratios 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.

About The Author
Growing up, my father always believed that every family needed a truck—there’s just something about having a vehicle capable of hauling anything at a moment’s notice. That philosophy stuck with me, and it’s been the foundation of my lifelong passion for Ford trucks.
While I’m best known for my work with Ford Rangers, I’ve owned a wide variety of Ford trucks over the years—including F-150s, F-250s, F-350s, and even larger rigs like the Ford Excursion, Ford Expedition, and a 1982 Ford Econoline Sportsmobile camper van. I’ve used these vehicles for everything from family transportation to towing car trailers and campers, and each one has fueled my love for Ford’s versatility and durability.
I especially enjoy the styling of 1970s and 1980s Ford trucks—the bold designs, rugged presence, and classic charm are timeless. Sharing my passion for Ford trucks, vans, and SUVs with other enthusiasts online brings me a great deal of joy, and it’s why I created Blue Oval Trucks.
This website is dedicated to helping Ford truck enthusiasts explore, learn about, and celebrate these incredible vehicles. While I share my expertise and experiences here, Blue Oval Trucks is an independent enthusiast site and is not affiliated with Ford Motor Company.
