How much can a 2018 F-550 tow?
In short, a 2018 Ford F-550 can tow roughly 15,000 to 30,000 pounds, depending on configuration. Diesel-powered, dual-rear-wheel versions with heavy-duty tow packages generally sit toward the higher end, while base gasoline setups tow less. The precise figure depends on engine, transmission, axle ratio, cab/bed configuration, and whether you’re pulling with a bumper hitch or a gooseneck/fifth-wheel. Always verify the exact rating for your truck’s build.
What determines towing capacity?
Several key factors govern how much an F-550 can tow. Ford publishes ratings that reflect the combination of engine, transmission, drivetrain, axle gearing, and hitch type. Because the F-550 is offered in many configurations, the number can vary widely even within the same model year.
Engine and transmission
The 2018 F-550’s towing figures are highest with the available 6.7L Power Stroke V8 turbo diesel, typically paired with a heavy-duty automatic transmission. An optional gasoline engine (if equipped in some cab-and-chassis configurations) generally yields lower tow ratings. Diesel power usually provides greater torque for towing large loads.
Drivetrain and axle configuration
Single rear wheel (SRW) versus dual rear wheels (DRW), along with 4x2 versus 4x4, strongly influences towing capacity. DRW setups tend to support higher trailer weights and gracious payloads, while 4x4 adds capability for rough terrain but can slightly reduce peak towing numbers due to extra drivetrain weight and gearing.
Hitch type and towing package
Wiring, trailer brake control, exhaust brake, cooling enhancements, and built-in trailer sway control are part of towing packages. Gooseneck/fifth-wheel packages change the rating as well, enabling heavier gooseneck or fifth-wheel towing compared with a standard bumper pull.
Typical towing ranges by configuration
The following ranges reflect common configurations for the 2018 F-550 and are intended as a guide. Exact figures vary by model and equipment.
- Conventional bumper-pull towing (diesel, DRW, 4x4, heavy-duty tow package): roughly 20,000 to 25,000 pounds.
- Conventional bumper-pull towing (diesel, DRW, 4x2, standard tow package): roughly 18,000 to 22,000 pounds.
- Conventional bumper-pull towing (gas engine option, DRW or SRW): roughly 12,000 to 15,000 pounds.
Conventional bumper-pull figures above assume standard trailers and typical road conditions; real-world numbers can vary based on payload, ballast, and trailer brake setup.
- Gooseneck/fifth-wheel towing (diesel, DRW, heavy-duty setup): up to around 30,000 pounds.
Gooseneck/fifth-wheel ratings are separate from bumper-pull ratings and depend on hitch type, frame strength, and specific axle ratings. Always verify the exact rating for your configuration.
How to find your exact rating
To determine the precise towing limit for your 2018 F-550, use the following steps.
- Check the door‑jamb placard on the driver’s side for the Gross Vehicle Weight Rating (GVWR) and Gross Combined Weight Rating (GCWR). These figures help determine how much you can tow without exceeding the vehicle’s limits.
- Review the window sticker or the Ford Build & Price/spec sheets for your exact truck configuration, including engine, transmission, axle ratio, and DRW vs SRW.
- Consult the owner's manual’s towing section for official guidelines and cautions related to hitch type and trailer brakes.
- When in doubt, contact a Ford dealer or use Ford’s online towing guides or the Ford Owner app to retrieve the specific rating for your build.
Important: Do not exceed the published tow rating for your exact configuration. Exceeding ratings can compromise braking, handling, and safety, and may affect warranty coverage.
Summary
The 2018 Ford F-550 offers a wide range of towing capabilities that depend on engine choice, drivetrain, axle ratio, and hitch configuration. With the diesel powertrain and a dual-rear-wheel setup, conventional bumper-pull towing commonly falls in the 20,000–25,000 pound range, while fifth-wheel/gooseneck setups can approach 30,000 pounds in many builds. Gas configurations and lighter-duty setups sit toward the lower end of the spectrum. For the exact figure, check the door placard, the vehicle’s official spec sheet, and the owner’s manual, or consult a Ford dealer with your vehicle’s precise build.
