Introduction
The 2017-2019 Ford F-350 Super Duty with the 6.7-liter Power Stroke diesel and automatic transmission was a cornerstone of Ford’s commercial and personal-use truck offerings. Built on the F-250/350/450 platform (often referred to as the “Super Duty” line), this variant specifically catered to buyers needing substantial towing and hauling capabilities without stepping up to the even heavier-duty F-450. The Super Cab configuration provided additional interior space compared to the standard cab, making it suitable for crews or families, while the long bed maximized cargo capacity. This particular trim level was positioned as a mid-range offering, balancing capability with a more accessible price point than the fully-loaded Lariat or Platinum trims.
Powertrain & Engine Architecture
At the heart of this F-350 variant lies the 6.7-liter Power Stroke Turbo Diesel V8. This engine, designated with various internal codes depending on the specific year and calibration, is a robust and highly capable powerplant. It utilizes a cast iron block and aluminum cylinder heads, featuring a single turbocharger with a variable geometry turbine (VGT) for improved responsiveness and efficiency. The fuel injection system is a high-pressure common rail system, delivering fuel directly into the cylinders at extremely high pressures for optimal combustion. The engine employs an overhead valve (OHV) valvetrain, known for its simplicity and durability. The 6R140 TorqShift six-speed automatic transmission is specifically designed to handle the high torque output of the Power Stroke diesel. This transmission features a heavy-duty torque converter and robust internal components to ensure reliability under demanding conditions. The transmission’s gear ratios are optimized for both towing and fuel efficiency, providing a balance between power delivery and economy.
Driving Characteristics
The F-350 Super Duty 4×4 with the 6.7L diesel and automatic transmission delivers a driving experience focused on capability and control. While not as nimble as lighter-duty trucks, it provides a surprisingly comfortable ride, especially considering its heavy-duty nature. The automatic transmission shifts smoothly and efficiently, providing ample power for accelerating and maintaining speed, even when towing heavy loads. The 4×4 system offers excellent traction in various conditions, making it suitable for both on-road and off-road use. Compared to the manual transmission versions, the automatic offers greater convenience, particularly in stop-and-go traffic or when navigating challenging terrain. However, some drivers may prefer the more direct control offered by a manual gearbox. The 450 horsepower and 934 lb-ft of torque provide ample pulling power, allowing the truck to handle substantial trailers and payloads with ease.
Equipment & Trim Levels
The 2017-2019 F-350 Super Duty in this configuration typically came standard with features such as air conditioning, power windows and locks, a basic audio system, and a rearview camera. The Super Cab configuration offered a split bench seat in the rear, providing seating for up to six passengers. Optional extras included upgraded audio systems, navigation, leather upholstery, heated and ventilated seats, and a variety of driver-assistance technologies. The XL trim, being the base level, offered a more utilitarian interior, while higher trims like XLT added more comfort and convenience features.
Chassis & Braking
The F-350 Super Duty features a heavy-duty chassis designed to withstand the stresses of demanding work. The front suspension utilizes a two-stage leaf spring design with a stabilizer bar, while the rear suspension employs leaf springs. This setup provides a robust and durable ride, capable of handling heavy loads. The braking system consists of ventilated discs on all four wheels, providing ample stopping power. An Anti-lock Braking System (ABS) is standard, enhancing safety and control during emergency braking situations. The steering system is a hydraulic recirculating ball system, offering a solid and predictable feel.
Market Reception & Comparison
The 2017-2019 Ford F-350 Super Duty was generally well-received by critics and consumers alike. It was praised for its robust construction, powerful engine, and impressive towing and hauling capabilities. Compared to other trucks in its class, such as the Ram 3500 and Chevrolet Silverado 3500, the F-350 offered a competitive combination of performance, features, and value. Fuel economy, as expected for a heavy-duty diesel truck, was not a strong point, but it was comparable to other trucks in the segment. Reliability was generally good, although some owners reported issues with the turbocharger and fuel injection system.
Legacy
The 6.7-liter Power Stroke diesel engine has proven to be a durable and reliable powerplant, and the 2017-2019 F-350 Super Duty remains a popular choice in the used truck market. These trucks are often sought after by buyers needing a capable and dependable workhorse. While maintenance costs can be higher than those of gasoline-powered trucks, the longevity and towing capacity of the Power Stroke diesel make it a worthwhile investment for many. The TorqShift transmission has also proven to be a robust and reliable unit, capable of withstanding years of heavy use. Overall, the F-350 Super Duty IV with the 6.7-liter diesel and automatic transmission represents a solid and capable truck that continues to provide value to its owners.
