What is the top speed of the Ford F-350?

In practice, the Ford F-350's top speed is electronically limited and varies by engine, drivetrain, tires, and configuration. This article provides current, authoritative information on expected speeds and what influences them.

How fast the F-350 can go

The Ford F-350 is not designed as a speed-focused vehicle. Its top speed is governed by electronic limits and safety considerations, particularly when towing heavy loads. Real-world speeds depend on engine choice, axle ratio, and tire size.

Typical top speeds by configuration

Below is a general guide to the top speeds you can expect from common F-350 configurations. Exact figures can vary by model year, market, and any factory or dealer-installed options. Always refer to your owner’s manual or the vehicle’s speed limiter indicator for precise values.

• Gasoline engines (6.2L V8; 7.3L V8) with standard gearing: typically around 100–105 mph (160–169 km/h).


• Diesel engine (6.7L Power Stroke) with standard gearing: typically around 105 mph (169 km/h) or slightly higher depending on tires and gearing.


• Configurations with different rear-axle ratios or heavy-duty tires may shift the limit slightly up or down within a narrow band.

The exact top speed is controlled by the vehicle's engine control unit and varies with options. It’s important to drive within safe limits, particularly when towing heavy loads, as high-speed operation can affect braking and stability.

Factors that influence top speed

Several variables determine the F-350's top speed in practice. Understanding them helps explain why two trucks with the same model year may reach different maximums.

• Engine choice and horsepower


• Payload and towing weight


• Gear ratio / rear axle configuration


• Tire size and type


• Transmission type and programming


• Vehicle safety electronics and speed limiter settings

When in doubt, consult your dealer or owner’s manual for the precise limiter setting for your specific configuration and observe all safety guidelines when operating a heavy-duty pickup at speed.

Summary

The Ford F-350’s top speed is typically limited to about 100–105 mph (160–169 km/h) for most configurations, with small variations based on engine, gearing, and tires. It is designed for torque, payload, and towing capability, not speed. Always prioritize safe driving and adhere to posted speed limits, especially when hauling heavy loads.

Summary note: The top speed of any given F-350 can vary by year, trim, and options. For the exact figure on your truck, check the owner's manual or contact a Ford dealer with your VIN.

How much horsepower does a 6.8 Ford F350 have?

What year did the Ford F350 go to 10-speed transmission?

The Ford F-350 received a 10-speed transmission for the 2020 model year. Ford introduced the new 10R140 TorqShift automatic transmission for the Super Duty trucks, including the F-350, with the 2020 model year facelift.
 

• Model year: The 10-speed transmission became standard on the F-350 in 2020. 
• Transmission name: This was the 10R140 TorqShift automatic transmission. 
• Other updates: The 2020 model year also included other changes, such as a new front end, new engine components, and an updated diesel engine. 

How do I turn off my Ford speed limiter?

Ford speed limiter removal typically involves reprogramming the Powertrain Control Module (PCM) using diagnostic tools like Ford IDS, or using third-party software like Forscan on certain models. Some vehicles may have a factory-set speed limiter that can be disabled via the "My Key" system through the instrument cluster settings, but this is different from a professionally installed limiter. Professional tuning companies can also remap the ECU to remove or adjust the limiter, sometimes alongside other performance upgrades.

Methods for speed limiter removal

• Using Ford IDS or a similar professional tool: Technicians can use dealer-level software like IDS to access programmable parameters and disable the speed limiter directly. 
  • Process: Connect the tool to the vehicle, navigate to module programming, programmable parameters, and speed items, and then select "Disable Speed Limiter". 
  • Note: This method is often used for commercial vehicles like the Ford Transit. 
• Using Forscan: On some models, Forscan can be used to remove or adjust the speed limiter. You'll need an OBDII adapter and the Forscan software. 
  • Note: Forscan may not work for all models, and some limitations exist, such as not being able to remove all types of speed limiters, as mentioned on Facebook. 
• Professional ECU remapping/tuning: Performance tuning companies can remap the ECU to remove the speed limiter. 
  • This process can be done by either sending the module to them for reprogramming or by visiting a dealer who has the necessary tools. 
• Disabling "My Key": If your vehicle has a factory-installed speed limiter, you may be able to disable it by clearing the "My Key" settings. This is a user-accessible feature, unlike professional limiter removal. 
  • Process: Find the "My Key" option in the instrument cluster and follow the prompts to clear the settings.

Things to consider

• Vehicle type: The method of removal can vary depending on the vehicle. Commercial vehicles like the Ford Transit may use a different process or have different limitations than other Ford models. 
• Safety and legal implications: Removing a speed limiter can void your warranty and may lead to excessive wear and tear, reducing the lifespan of your vehicle. It is crucial to understand the risks before proceeding. 
• Professional help: If you are not comfortable with the process, it's best to consult a professional tuner or a Ford dealer for assistance.
