Ford's F-Series Super Duty pickup trucks are built on a fully boxed frame made of 95 percent high-strength steel. The platform shaves nearly 350 pounds from the curb weight of its predecessor while strength is increased by a factor of 24 over the previous generation's frame. Riding atop it is a high-strength aluminum alloy body, which Ford describes as military-grade.
The F-Series Super Duty provides buyers with best-in-class towing capabilities. In properly equipped F-450s, that means up to 24,200 pounds of conventional capacity and an impressive 32,500-pound capacity when hooked up to a fifth wheel. Meanwhile, the F-250 offers best-in-class payload capacity of 4,200 pounds, while the F-350's best-in-class payload tops out at 7,850 pounds. In short, the Super Duty hauls.
These F-Series Super Duty trucks are powered by a variety of engines. Standard is a flex fuel 6.2L gasoline V8 that makes 385 horsepower and 430 pound-feet of torque. Ford's 430 horsepower 7.3L V-8 is optional and also gets buyers a better 10-speed transmission. Finally, a second-generation 6.7L Power Stroke turbo diesel V8 delivers best-in-class power figures of 475 horsepower and an incredible 1050 lb-feet of torque. The base engine is mated to a TorqShift 6-speed automatic transmission, while the diesel and 7.3L engines are both mated to the new 10-speed automatic.
Ford's Super Duty pickups are offered in a variety of three-quarter and one-ton configurations--F-250, F-350, F-450--in both 2- and 4-wheel drive, with cabs including regular cab, extended super cab, and 4-door crew cab. Bed sizes include lengths of 6-feet 9-inches and 8 feet, with both standard rear-wheel and dually configurations.
Trims across the range include XL, XLT, Lariat, King Ranch and Platinum. XL models include things like 17-inch steel wheels, quad dual-beam halogen headlights, tie-down hooks, heavy-duty vinyl on a 40/20/40 split bench front seat, air conditioning, an AM/FM stereo with either four or six speakers depending on cab size, 12-volt power outlets, tilt/telescoping steering wheel, AdvanceTrac with roll stability control and trailer sway control.
XLT trims add 18-inch alloy wheels, a SYNC infotainment system, SiriusXM satellite radio, three 12V power outlets, two USB ports cruise control and cloth seating. The Super Duty Lariat adds luxury to the fold, with leather seating, a center console, the SYNC 3 infotainment system with voice activation and optional navigation, power driver and passenger seats, dual-zone automatic climate control, a Bang & Olufsen 10-speaker audio system with CD/MP3 player, power-adjustable pedals, an 8-inch productivity screen and rear privacy glass with a power sliding back window in crew and super cabs.
The King Ranch trim comes only on crew cab models. It includes all the Lariat's standard features, plus an accent-color bumper, 2-tone paint, running boards, special alloy wheels, remote start, special Mesa brown leather seating with heated and cooled front seats, a heated leather-wrapped steering wheel, voice-activated navigation, a reverse sensing system, universal garage door opener and more.
The crew cab-only Platinum trim rides on 20-inch wheels and features LED headlights, fog lights and taillights, power running boards, remote tailgate with a built-in tailgate step, adaptive steering and blind-spot monitoring with rear cross-traffic alert.
A power sunroof, adaptive cruise control, LED bed lighting, and lane-keeping assist are also optional. The available Ultimate Trailer Tow Camera System features seven cameras that allow drivers to better maneuver a trailer during hook up backing and towing.
There's no way around it: the 2021 Ford F-350 King Ranch Tremor Crew Cab is a lot of truck. In fact, it's probably too much truck for most people, most of the time. That ratchets up even further when you add in the utterly ridiculous diesel V8 engine and its 1,050 pound-feet of torque. But serious hauling calls for a serious truck with serious capability. And here's the thing, I seriously love it.
The heart of this particular F-350 Super Duty is Ford's excellent 6.7-liter PowerStroke diesel V8, paired with a 10-speed automatic transmission. This engine has been continually refined for the last decade and now produces 475 horsepower at 2,600 rpm and a borderline stupid 1,050 pound-feet of torque at just 1,600 rpm.
Those numbers are impressive on their own, but the way the PowerStroke delivers that performance is almost more so. The 6.7 is a highly modern diesel, delivering power effortlessly and smoothly. It's also relatively quiet and thanks to the advanced emissions control equipment it's packing, it doesn't really have that characteristic diesel smell, either.
The Good ~ Strong diesel engine ~ Tremor is way more than an appearance pack
The Bad ~ Outdated Sync 3 tech ~ Lacks some driver-assistance features ~ Pretty expensive
The Bottom Line If you actually need a full-size, one-ton truck that goes off-road, the F-350 Tremor is as good as it gets.
