Powertrain & Engine Architecture
The heart of this F-350 variant is the 6.7-liter Power Stroke V8 diesel engine. This engine, designated with various internal codes depending on the specific year and calibration, is a turbocharged, intercooled diesel featuring a cast iron block and aluminum cylinder heads. The 2017-2019 iteration benefited from continuous refinement, including improvements to the turbocharger and fuel injection system. The engine utilizes a high-pressure common rail fuel injection system, delivering fuel directly into the cylinders at extremely high pressures for optimized combustion. The valvetrain employs an overhead valve (OHV) configuration, known for its simplicity and durability. The TorqShift 6-speed automatic transmission is a heavy-duty unit designed to handle the substantial torque output of the Power Stroke engine. It features a wide gear ratio spread, allowing for both strong acceleration and efficient highway cruising. The transmission is electronically controlled, adapting shift points based on driving conditions and load.
Driving Characteristics
The 450 horsepower and 1267 lb-ft of torque delivered by this powertrain combination resulted in impressive performance for a heavy-duty truck. While not as quick as lighter-duty pickups, the F-350 offered ample power for towing and hauling even the most demanding loads. The automatic transmission provided smooth and predictable shifts, making it easy to manage the truck’s power. Compared to the 6.2-liter gasoline V8 option, the diesel offered significantly more torque at lower RPMs, making it ideal for towing. Compared to higher-output diesel variants (often exceeding 475 hp), this version prioritized a balance of power and fuel economy. The gear ratios in the TorqShift transmission were optimized for both work and highway driving, providing a comfortable experience in various conditions.
Equipment & Trim Levels
The F-350 Super Duty IV Crew Cab Short Box 6.7d V8 (450 Hp) 4×4 Automatic SRW was typically offered in higher trim levels like XLT, Lariat, and King Ranch. Standard features generally included air conditioning, power windows and locks, a basic infotainment system, and a rearview camera. Lariat trims added leather upholstery, heated and ventilated front seats, a premium sound system, and more advanced technology features. King Ranch models represented the pinnacle of luxury, with upgraded leather, unique exterior trim, and a host of convenience features. Optional extras included a navigation system, a sunroof, and various towing packages.
Chassis & Braking
The F-350 Super Duty IV featured a fully-boxed frame constructed from high-strength steel, providing a solid foundation for the truck. The front suspension utilized a two-stage leaf spring design with anti-roll bar, while the rear suspension employed leaf springs. This setup was designed to handle heavy loads while maintaining a comfortable ride. Braking duties were handled by ventilated disc brakes on all four wheels, providing ample stopping power. An Anti-lock Braking System (ABS) was standard. The robust chassis and braking system were crucial for managing the truck’s substantial weight and towing capacity.
Market Reception & Comparison
The 2017-2019 Ford F-350 Super Duty with the 6.7-liter Power Stroke diesel and TorqShift automatic received generally positive reviews. Critics praised its powerful engine, comfortable ride, and impressive towing capabilities. Fuel economy, while not exceptional, was considered reasonable for a truck of its size and capability. Compared to the gasoline-powered F-350, the diesel offered superior torque and towing capacity, but at a higher initial cost. Compared to competitors like the Ram 3500 and Chevrolet/GMC 3500, the F-350 was often lauded for its refined interior and advanced technology features.
Legacy
The 6.7-liter Power Stroke diesel engine has proven to be a durable and reliable powerplant, and the TorqShift transmission has also demonstrated good longevity. These trucks continue to hold their value in the used car market, particularly those that have been well-maintained. While diesel engines require more diligent maintenance than gasoline engines (including regular diesel exhaust fluid (DEF) refills), the long-term reliability and towing capabilities of this F-350 variant make it a popular choice for buyers seeking a capable and dependable heavy-duty truck. Common issues reported include occasional turbocharger failures and issues with the fuel injection system, but these are generally not widespread and can be mitigated with proper maintenance.
