The 2025 Ford F-550 Super Duty is the heaviest truck in Ford’s commercial lineup before you hit Class 6 territory. With a GVWR of up to 19,500 lbs and a purpose-built Cab & Chassis platform, the F-550 is designed from the ground up for heavy upfitting. If you’re running a demanding service fleet, need maximum crane capacity, or hauling serious gooseneck loads, the F-550 is where professionals start.

2025 F-550 Key Specs

  • GVWR: Up to 19,500 lbs
  • Max Payload: Up to 12,750 lbs (Cab & Chassis)
  • Engine Options: 6.7L Power Stroke Diesel (most commercial specs), 7.3L Gas V8
  • Max Towing (5th Wheel): Up to 40,000 lbs
  • Rear Configuration: DRW standard on all models

F-550 Cab-to-Axle (CA) Measurements

The F-550 Cab & Chassis is available in extended CA configurations not available on the F-350 or F-450. This makes it ideal for long service bodies, stake beds, and dump configurations:

  • Regular Cab: CA ≈ 84″, 108″, 132″
  • SuperCab: CA ≈ 84″, 108″
  • Crew Cab: CA ≈ 60″, 84″, 108″, 132″

The 108″ and 132″ CA options on the F-550 support long service bodies (11’–14′ body length) that simply won’t fit on smaller chassis. This is why the F-550 is the default choice for most commercial fleet operations.

Flatbed Options for the F-550

A heavy-duty DRW flatbed on the F-550 is a top choice for ranchers, construction haulers, and hotshot operators who regularly pull maximum-weight loads:

Bedrock Granite Series (Long Bed, DRW)

Bedrock builds custom and semi-custom flatbeds for F-550 CA dimensions. Their 3/16″ steel construction is rated for the loads the F-550 is capable of carrying. Available in 9’4″, 10’4″, and custom lengths for 108″+ CA trucks. Gooseneck-ready options available.

CM Truck Beds (F-550 DRW)

CM offers the RD and SK series in F-550 DRW sizes. For fleet operators running multiple trucks, CM’s competitive pricing and nationwide availability make them a practical choice. Available in 9’4″ and longer for F-550 CA specs.

Norstar for F-550

Norstar builds F-550-compatible flatbeds in their SD (standard deck) and RM (ranch) configurations. Texas-made and a popular choice in the South Texas ranch and ag market.

Service Bodies for the F-550

The service body is where the F-550 earns its keep in commercial operations. With a 108″+ CA Crew Cab, you can mount an 11′ or 12′ service body with full compartment runs on both sides, plus a rear crane if needed. This is the standard spec for:

  • Electrical and mechanical contractors with large tool inventories
  • Oil field service trucks carrying parts, chemicals, and hand tools
  • Telecom/utility field crews
  • Municipal maintenance departments

We stock and install STI service bodies and RKI service bodies in F-550-compatible lengths. Both brands offer aluminum and steel options with multiple compartment configurations.

Crane Bodies for the F-550

The F-550 is one of the most common chassis choices for crane body installations in the Texas oilfield and construction sectors. A crane body on an F-550 allows operators to:

  • Lift components up to 8,000–12,000 lbs depending on crane model
  • Work in locations where a full crane truck can’t access
  • Combine crane capability with service body storage

Ask about our STI crane body packages for F-550 — these are purpose-built for the commercial market and include proper crane subframe mounting.

Why the F-550 vs F-450?

If you’re deciding between the F-450 and F-550, the key questions are:

  • How heavy is your body + load? If you regularly need 8,000+ lbs of payload, the F-550 is the only choice.
  • How long a body do you need? The 132″ CA on the F-550 is not available on the F-450.
  • Do you need crane prep? The F-550’s frame and GVWR make it standard for most crane body installations.
