2021 FORD F350 SUPER DUTY CREW CAB

If you're searching for a 2021 Ford F-350 Super Duty Crew Cab for sale in Kent, WA, this blacked-out diesel powerhouse at North West Auto Empire deserves a serious look. With 101,377 miles on a platform built to go the distance, this truck is well into its working life but nowhere near its limits — and it's priced and positioned for buyers who know what heavy-duty capability actually looks like.

About This 2021 Ford F-350 Super Duty Crew Cab

This 2021 F-350 Super Duty Crew Cab arrives in a sharp black exterior finish and comes equipped with 4WD, making it ready for the job sites, mountain passes, and rainy Pacific Northwest roads that Kent-area drivers deal with every season. At just over 100,000 miles, this truck is in the sweet spot for used heavy-duty buyers — the initial depreciation has already done its work, and the 6.7L Power Stroke diesel is only beginning to hit its stride. Ford Super Duty trucks routinely reach 250,000 to 300,000 miles with proper maintenance, meaning this F-350 has plenty of road ahead of it.

2021 Ford F-350 Super Duty Performance and Engine

Under the hood sits Ford's legendary 6.7-liter Power Stroke turbocharged diesel V8 — one of the most capable and respected diesel engines in the heavy-duty truck segment. This engine produces up to 475 horsepower and 1,050 lb-ft of torque in its high-output configuration, giving you the pulling power to handle fifth-wheel trailers, heavy equipment hauls, and loaded flatbeds without breaking a sweat.

Backing that engine is Ford's 10-speed SelectShift automatic transmission with TorqShift technology. This transmission is purpose-built for towing and hauling, offering smooth power delivery under load and intelligent gear management that reduces driver fatigue on long pulls. The 4WD drivetrain adds confident traction whether you're navigating a muddy job site in Auburn or heading up into the Cascade foothills.

Ford F-350 Super Duty Features and Interior

The Crew Cab configuration gives you a full rear seat — genuinely useful for contractors who need to bring a crew, families hauling gear to outdoor destinations, or anyone who doesn't want to sacrifice passenger space for truck capability. The interior on this generation of Super Duty is a significant step forward from its predecessors, with improved materials, a more refined dash layout, and modern connectivity features. The 2021 model year brought refinements to Ford's SYNC infotainment platform, available 8-inch and 12-inch touchscreens, and driver-assist technologies that weren't standard on heavy-duty trucks just a few years earlier.

Ford F-350 Super Duty Reliability and Ownership

The 6.7L Power Stroke diesel earned its reputation over years of real-world heavy use. Ford redesigned this engine in-house after the Navistar partnership ended, and the result has been a powerplant that owners consistently praise for durability, fuel efficiency relative to its output, and manageable maintenance costs. Common ownership advice includes staying current on oil changes using the correct diesel-spec oil, monitoring the diesel exhaust fluid (DEF) system, and keeping an eye on injectors as mileage climbs — none of which are unusual for any modern diesel truck.

The F-350 platform itself is built on a fully boxed high-strength steel frame that resists flex under load, and the front axle and rear suspension are engineered for payloads and tow ratings that smaller trucks simply can't touch. Owners who maintain their Power Stroke Super Duties regularly report that 200,000 miles is a milestone, not a ceiling.

Frequently Asked Questions

Is the 2021 Ford F-350 Super Duty a good buy?

Yes — the 2021 F-350 Super Duty is widely considered one of the best heavy-duty trucks on the market. The 6.7L Power Stroke diesel is a proven, high-output engine, the 10-speed TorqShift transmission is purpose-built for towing, and the Crew Cab body gives you full passenger capacity alongside maximum capability.

How many miles is too many on a Ford F-350 diesel?

With the 6.7L Power Stroke diesel and proper maintenance history, 100,000 miles is considered relatively early in the truck's usable life. Well-maintained examples regularly reach 250,000 to 300,000 miles. A pre-purchase inspection and service history review are always recommended, but mileage alone shouldn't disqualify this truck.

What is SelectShift and TorqShift on the Ford F-350?

SelectShift is Ford's driver-controlled gear selection mode that allows manual shifting through the 10-speed automatic. TorqShift is Ford's proprietary transmission technology designed specifically for high-torque diesel applications — it manages gear changes under load more effectively than a standard automatic, reducing heat buildup and wear during towing.

What is the towing capacity of the 2021 Ford F-350 Super Duty?

The 2021 F-350 Super Duty is capable of towing up to approximately 21,000 pounds when properly equipped for conventional towing, and up to 40,000 pounds for fifth-wheel and gooseneck configurations depending on the configuration. Actual towing capacity depends on trim, axle ratio, and how the truck is equipped.

Does the 2021 Ford F-350 have 4WD?

Yes — this specific vehicle is equipped with 4WD, making it suitable for off-road use, towing on loose surfaces, and year-round driving in the Pacific Northwest where wet roads, mountain access, and variable terrain are everyday realities.
