Which Ford Trucks Are Aluminum? What Owners Need to Know

The Ford F-150 has had an aluminum-alloy body and bed since the 2015 model year. Ford’s F-250, F-350, and F-450 Super Duty pickups made the switch for 2017. If you own one, your old door magnets may need a new home.

I got a reminder of that while packing my F-150 for the first home football game. The tailgate gear was loaded, and I pulled the school magnets off the garage fridge to put them on the truck. I held one up to the door, expecting it to quickly adhere.

Then it hit me. Aluminum.

I had switched from window flags to magnets several years earlier because we drive about three hours to the games. The flags were noisy. The magnets let me show my school pride without listening to it flap beside the window all the way there.

Now I need new flags or another way to represent my school on the road. I still love driving the F-150. But that little moment with the magnets is a good example of how a construction detail you barely think about can change something you have done for years.

When did each Ford truck switch to aluminum?

For the full-size pickups, remember two model years: 2015 for the F-150 and 2017 for Super Duty. Ford’s 2015 F-150 brochure describes the new aluminum body and bed. Its 2017 Super Duty brochure introduces aluminum bodywork and cargo boxes on the F-250, F-350, and F-450 pickups.

That means a 2015 F-150 and a 2015 F-250 fall on opposite sides of the changeover. Look at the model year of the particular truck, rather than assuming everything with an F-Series badge changed together.

Truck	Body construction to know
F-150	Aluminum-alloy body and bed beginning with 2015. Ford’s 2026 fleet guide still identifies aluminum in the body, doors, and bed.
F-250, F-350, F-450 pickups	Aluminum-alloy body and cargo box beginning with 2017. The 2026 Super Duty pickup specifications continue to list an aluminum-alloy body.
F-150 Lightning	The electric pickup’s 2022 launch specifications list an aluminum-alloy body and bed.
Ranger	Ford describes the next-generation Ranger as having a steel body and steel frame.
Maverick	Ford’s detailed 2022 construction bulletin documents a steel unibody and mild-steel outer bodyside panels.

The Ranger and Maverick entries identify the construction documents used here. They should not be read as a material list for every individual panel or future model. And if you are looking at a commercial truck with a service body or flatbed, check who built that rear body and what it is made from. Factory pickup-box construction does not tell you what an upfitter installed.

Why won’t a door magnet stick to my F-150?

A regular vehicle magnet needs a surface that will hold it magnetically. An aluminum door will not do that. Magnum Magnetics specifically excludes aluminum and plastic panels in its instructions for flexible magnetic material.

So if a magnet works on your garage fridge and refuses to stay on the truck, the magnet may be working perfectly. The door is the problem for that particular accessory.

This matters for more than football fans. Before ordering magnetic business signs or moving an accessory from an older vehicle, establish whether the intended mounting surface is compatible. Body material belongs on the accessory checklist just as much as dimensions and fit.

For my school gear, going back to window flags is an option, although I already know how I felt about their noise on those long drives. I may find another way to show my school pride. I have not chosen or tested a replacement yet, so I cannot recommend one from experience.

What do you actually gain from the aluminum body?

Ford used aluminum to take weight out of its pickups. It advertised the redesigned 2015 F-150 as weighing up to 700 pounds less than its predecessor. That was a maximum reduction for the vehicle, with multiple design changes contributing. The reduction varied with the truck’s configuration.

The 2017 Super Duty took a different approach to those savings. Ford says it put weight back into components such as the frame, axles, and driveline, while the finished truck weighed up to 350 pounds less than before. Reducing body weight gave the engineers room to improve other parts of the truck.

As an owner, I spend much more time appreciating the way my F-150 drives than thinking about what its doors are made from. The seats are comfortable, I like the long wheelbase, and I am getting over 20 mpg with the PowerBoost hybrid. It suits those three-hour football trips well.

Those are my impressions and my fuel economy, rather than a mileage promise for everyone who buys a PowerBoost. They also do not isolate the benefit of aluminum. The powertrain and the rest of the truck’s design are part of that experience.

If you are comparing trucks, use the fuel-economy rating for the actual configuration. For carrying tailgate equipment or towing a trailer, use the vehicle’s payload label and its model-year towing information. The aluminum body is already part of the design behind those ratings. It does not give you extra capacity to add on top.

Does aluminum mean the truck cannot rust?

The body panels avoid the red rust you associate with steel, but the F-150 and Super Duty pickups still have steel frames. Ford describes that distinction in the original brochures, and the 2026 Super Duty specifications list the steel frame and aluminum body separately.

That is why I would still want to see underneath a used truck with beautiful bodywork. Clean doors and bedsides cannot answer questions about the frame.

Aluminum can also corrode. In bulletin Q-222, Ford warns about galvanic corrosion where aluminum contacts dissimilar metals. Its accessory-installation guidance calls for protecting damaged paint and isolating those metals.

On a truck with added racks, toolboxes, or brackets, ask how they were mounted. A previous owner may have selected equipment that fit the truck without paying enough attention to the material it attached to. Have questionable installations assessed rather than relying on appearances.

What would I include in a used Ford truck inspection?

I would treat the body as one part of the inspection. These are the five checks I would want completed:

1. Confirm the truck and model year. Make sure the listing and records describe the vehicle you are inspecting, with the correct F-150 or Super Duty changeover year.
2. Have the underside inspected. Ask a qualified shop to assess the steel frame and underbody for corrosion and damage.
3. Investigate suspicious bodywork. Uneven gaps, damaged panels, or questionable paint deserve a body-shop assessment.
4. Request collision-repair records. Find out what was repaired and which shop performed the work.
5. Review accessories and intended use. Check mounting methods, confirm your accessories work with the body material, and verify the truck’s load ratings.

Repair history deserves attention because aluminum bodywork calls for the appropriate equipment and procedures. Ford identifies aluminum-repair capabilities among the requirements for its Certified Collision Network.

I would get an estimate for actual damage before buying, rather than budgeting from a general claim that aluminum repairs are cheap or expensive. The panel involved, the repair it needs, and the shop doing the work determine the quote.

Would aluminum stop me from buying an F-150?

No. I enjoy mine, and the comfortable seats, long wheelbase, and fuel economy matter much more to my regular use than the inconvenience of replacing my school magnets.

For someone shopping, I would choose the size and capability needed, then look for a truck in good condition with a repair history I could understand. An aluminum body is a useful feature, particularly when body rust is a concern. It would not persuade me to overlook a damaged frame or questionable collision work.

And before the next home game, I need to sort out the school pride part. The truck is ready for the drive. My old magnets will have to cheer from the garage fridge.
