The Ford F-350 Super Duty III Crew Cab Long Box, equipped with the 6.7-liter V8 Power Stroke Turbo Diesel engine producing 400 horsepower and paired with a 6-speed automatic transmission, represents a significant iteration in Ford’s long-standing tradition of heavy-duty pickup trucks. Produced from 2011 to 2016, this variant occupied a sweet spot in the F-350 lineup, offering a balance of substantial towing capacity, comfortable interior space, and modern diesel technology. It was positioned as a workhorse for those needing more capability than the F-250 offered, but didn’t necessarily require the ultimate hauling capacity of the F-450.

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 codes depending on the specific year and emissions configuration, represented a significant leap forward in Ford’s diesel offerings. It featured a cast iron block, aluminum cylinder heads, and a sophisticated turbocharging system with an intercooler. The engine utilized a high-pressure common rail direct fuel injection system, delivering fuel directly into the cylinders at extremely high pressures for optimized combustion. The valvetrain employed an overhead valve (OHV) configuration, a design choice favored for its durability and simplicity. The 6-speed TorqShift automatic transmission was specifically designed to handle the substantial torque output of the Power Stroke engine. It featured a robust construction and intelligent shift programming to provide smooth and efficient power delivery.
Driving Characteristics
The 400 horsepower and 800 lb-ft of torque produced by this engine/transmission combination provided ample power for demanding tasks. While not as quick off the line as some gasoline-powered trucks, the diesel engine’s torque curve delivered strong pulling power across a wide RPM range. The automatic transmission, while generally smooth, could sometimes feel hesitant during downshifts, particularly when heavily loaded. Compared to the 5.0L gasoline V8 or the 6.2L gasoline V8 options, the diesel offered significantly more low-end torque, making it ideal for towing and hauling heavy loads. Compared to higher-output versions of the 6.7L Power Stroke (like those found in later model years or with aftermarket modifications), this 400hp variant offered a more manageable power delivery and potentially better fuel economy.
Equipment & Trim Levels
The F-350 Super Duty III Crew Cab Long Box 6.7L Diesel was typically available in several trim levels, including XL, XLT, and Lariat. The XL trim was the base model, offering essential features like air conditioning, power windows and locks, and a basic audio system. The XLT trim added features such as chrome exterior trim, upgraded upholstery, and a more advanced audio system. The Lariat trim represented the premium offering, with leather upholstery, heated and cooled front seats, a navigation system, and a premium sound system. Standard features across most trims included a heavy-duty suspension, four-wheel drive, and a trailer brake controller. Optional extras included a sunroof, upgraded wheels, and various electronic convenience features.
Chassis & Braking
The F-350 Super Duty featured a robust chassis designed to withstand heavy loads and demanding conditions. The front suspension utilized a solid axle with coil springs and stabilizer bar, while the rear suspension employed a leaf spring setup. This configuration provided a comfortable ride while maintaining excellent load-carrying capacity. Braking duties were handled by ventilated disc brakes on all four wheels, providing ample stopping power. An Anti-lock Braking System (ABS) was standard equipment. The steering system was hydraulic, offering a responsive and precise feel.
Market Reception & Comparison
The 2011-2016 Ford F-350 Super Duty with the 6.7L Power Stroke diesel and automatic transmission was generally well-received by critics and consumers alike. It was praised for its powerful engine, comfortable ride, and spacious interior. Fuel economy, while not exceptional, was considered reasonable for a heavy-duty truck of its size and capability. Compared to the gasoline-powered F-350 models, the diesel offered significantly better fuel economy when towing or hauling heavy loads. 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 examples of this generation F-350 are still commonly found on the used car market today. With proper maintenance, these engines can easily exceed 200,000 miles. The combination of a powerful diesel engine, a capable chassis, and a comfortable interior has made this F-350 variant a popular choice for those needing a heavy-duty truck for work or recreation. Its continued presence in the used market is a testament to its enduring appeal and overall quality.
