INTRODUCTION
The 2017-2019 Ford F-350 Super Duty IV Crew Cab Long Box, equipped with the 6.7-liter Power Stroke diesel and automatic transmission, was positioned as a premium work truck within Ford’s Super Duty range. It catered to buyers needing substantial towing and payload capacity, often for commercial purposes or demanding recreational activities. The fourth-generation Super Duty (introduced in late 2016 as a 2017 model) represented a major overhaul, utilizing a high-strength steel frame and fully-boxed construction for increased rigidity and capability. The Crew Cab configuration offered spacious seating for six passengers, while the Long Box provided ample cargo space. The Dual Rear Wheel (DRW) setup further enhanced stability and payload capacity, making it ideal for heavy-duty applications.
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 throughout its production run, is a turbocharged and intercooled diesel featuring a cast iron block and aluminum cylinder heads. The 2017-2019 iteration benefited from significant updates, including a redesigned turbocharger, improved fuel injectors, and a strengthened crankshaft, resulting in the 450 horsepower and 935 lb-ft of torque output. The engine utilizes a diesel common rail fuel injection system, delivering highly pressurized fuel directly into the cylinders for efficient combustion. The overhead valve (OHV) valvetrain, while traditional, proved robust and reliable. The TorqShift 6-speed automatic transmission is specifically designed to handle the high torque output of the Power Stroke diesel. It features a heavy-duty torque converter and reinforced gears to ensure durability under demanding conditions. The transmission is electronically controlled, offering smooth shifting and optimized gear selection based on driving conditions and load.
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 stability rather than outright speed. While 450 horsepower is substantial, the truck’s considerable weight (over 7,600 lbs) means acceleration is brisk but not sporty. The TorqShift transmission is programmed for smooth, deliberate shifts, prioritizing towing performance and fuel efficiency. The real strength of this powertrain lies in its ability to effortlessly handle heavy loads. When towing, the transmission downshifts promptly to maintain power and control, while the DRW configuration provides exceptional stability. Compared to the gasoline-powered F-350 variants, the diesel offers significantly more torque at lower RPMs, making it ideal for hauling and steep grades. Compared to higher-output diesel trims, this 450hp version offers a balance between power and fuel economy, making it a practical choice for those who don’t consistently require maximum towing capacity.
Equipment & Trim Levels
The F-350 Super Duty IV Crew Cab Long Box 6.7d V8 Automatic DRW was typically offered in several trim levels, including XL, XLT, Lariat, King Ranch, and Platinum. The base XL trim provided essential work-truck features, while the higher trims added increasing levels of luxury and convenience. Standard equipment on most models included air conditioning, power windows and locks, a basic audio system, and steel wheels. Higher trims featured leather upholstery, heated and ventilated front seats, a premium sound system, navigation, and advanced driver-assistance systems like adaptive cruise control and lane departure warning. Optional extras included a power moonroof, upgraded wheels, and various towing packages. The interior design prioritized functionality and durability, with large, easy-to-use controls and ample storage space.
Chassis & Braking
The F-350 Super Duty’s chassis is built around a high-strength steel frame designed to withstand extreme loads. The front suspension utilizes a dependent spring setup with an anti-roll bar, while the rear suspension employs a rigid axle with leaf springs. This configuration provides a robust and durable platform for heavy-duty applications. The braking system features ventilated discs at all four wheels, providing ample stopping power even when heavily loaded. An Anti-lock Braking System (ABS) is standard, enhancing safety and control. The steering system is a hydraulic power-assisted recirculating ball system, offering precise control and feedback. The DRW configuration significantly increases the truck’s stability and load-carrying capacity, but also results in a wider overall footprint.
Market Reception & Comparison
The 2017-2019 Ford F-350 Super Duty was widely praised by automotive critics for its increased capability, improved ride quality, and advanced technology. The 6.7-liter Power Stroke diesel engine received positive reviews for its power and reliability. Compared to the previous generation, the fourth-generation Super Duty offered a noticeable improvement in towing capacity and overall refinement. Compared to the gasoline-powered F-350 variants, the diesel offered superior torque and fuel economy when towing heavy loads. However, the diesel engine also carried a higher price tag and potentially higher maintenance costs. Against competitors like the Ram 3500 and Chevrolet Silverado 3500, the F-350 Super Duty consistently ranked among the top contenders in the heavy-duty truck segment.
Legacy
The 6.7-liter Power Stroke diesel engine has proven to be a durable and reliable powertrain, with many examples exceeding 200,000 miles with proper maintenance. The 2017-2019 F-350 Super Duty remains a popular choice in the used truck market, commanding relatively high resale values due to its capability and reputation. While some early models experienced issues with the fuel injection system, these were largely addressed through software updates and revised components. The DRW configuration, in particular, is highly sought after by those needing maximum towing and payload capacity. This generation of F-350 Super Duty solidified Ford’s position as a leader in the heavy-duty truck segment, setting a new standard for capability and refinement.
