2018 Ford Super Duty XLT SuperCab in Oxford White with chrome 2 bar style grille


Super Duty® Chassis Cab gas engines — the 6.2L V8 (F-350) and 6.8L V10 (F-450/F-550) — deliver all the power you’d need for the tough everyday jobs you face on the job site or on the road. Teamed with the proven Ford TorqShift® SelectShift® 6-speed automatic, both engines can be equipped with the available Live-Drive power takeoff (PTO) provision with Mobile Mode. For heavy-duty diesel performance, the latest generation of the available Power Stroke® Turbo Diesel V8 is the most powerful ever in a Ford Super Duty® Class 3-5 chassis cab.
6.7L Power Stroke Turbo Diesel V8


The latest generation of the available B20-capable 6.7L Power Stroke® Turbo Diesel V8 delivers 330 horsepower and 750 lb.-ft. of torque. The Power Stroke features a unique inverse-flow configuration: The exhaust manifolds and turbocharger are mounted between the cylinder heads above the engine block. This inboard configuration allows a large single turbocharger to be mounted closer to the exhaust manifolds for faster air displacement and more power. Another notable feature is the compacted graphite iron engine block that is stronger yet lighter than cast iron.
6.8L Triton Gas V10


The class-exclusive* 6.8L Triton® V10 is the standard gas engine in Super Duty® XL and XLT F-450/F-550 chassis cabs. It’s teamed with the proven Ford TorqShift® SelectShift 6-speed automatic transmission and offers the available Live-Drive power takeoff (PTO) provision with Mobile Mode.

6.2L Gas V8 engine


Torque rules in big work trucks pulling big loads. And no other gas-powered Class 3-5 chassis cab* delivers as much torque (430 lb.-ft.) as the Super Duty® 6.2L V8, standard in the F-350. The 6.2L has tuning and camshaft configurations designed to increase peak torque at lower rpm. The optional Live-Drive power takeoff (PTO) provision with Mobile Mode is available with the 6.2L engine.

TorqShift SelectShift 6 Speed automatic transmission


The Ford TorqShift® SelectShift® 6-speed automatic transmission delivers high-torque performance and dependability. Big, strong gears can easily handle the heavy torque demands of the turbo diesel and gas engines. Fewer rpm are required because the torque converter locks up at lower speeds. The TorqShift offers SelectShift and Tow/Haul features. SelectShift has two modes: Progressive Range Select that limits the range of gears to lock out overdrive, plus Full Manual control. Tow/Haul selects the gear that minimizes gear hunting on uphills. On a downhill, it keeps the vehicle from upshifting and gaining speed, reducing reliance on brake pressure to slow down.

The available class-exclusive* Live-Drive power takeoff (PTO) provision with Mobile Mode** lets you power an aftermarket snowplow, pump, compressor or other accessory. The PTO provision is available across the entire engine line-up. An output gear connects directly to the engine crankshaft to power your PTO anytime the engine is running, whether the truck is in motion or stopped. Another big feature is “split-shaft” capability (diesel only) that allows multiple accessories to operate at the same time when the truck is stopped.

Driver activated diesel engine exhaust braking for enhanced downhill braking control


The 6.7L Power Stroke® Turbo Diesel incorporates a smart exhaust brake function. When activated with a button on the instrument panel, the engine brake restricts the turbocharger’s exhaust flow to generate back pressure and slow the vehicle. The main benefit is greater control while traveling downhill, regardless of vehicle load or road grade. Also, because the engine brake helps minimize having to apply pedal pressure, brake fade and lining wear are reduced, lowering the cost of maintenance. Three settings are available: On, Off and Auto. The Auto setting modulates engine braking as needed to help maintain the speed you want based on accelerator and brake pedal use.
Gas engines available with alternative compressed natural gas and propane fuel options


Compressed natural gas (CNG) and propane are alternative fuels to unleaded gasoline with the CNG/Propane Gaseous Engine Prep Package* for Super Duty® gas-powered models — available with the 6.2L V8 (F-350) and with the 6.8L V10 (F-450/F-550). The CNG/Propane Package with additional aftermarket upfits provides bi-fuel capability, enabling these engines to run on either liquefied propane gas or unleaded gas.
*Vehicle will be equipped with the standard factory gasoline fuel system. The CNG/Propane Gaseous Engine Prep Package includes hardened exhaust valves and valve seats. It does not include compressed natural gas/propane fuel tanks and lines, etc. See your dealer for details.
