2020 Chassis Cab



Super Duty® Chassis Cab gas engines — the 6.2L V8 and, new for 2020, the 7.3L V8 — deliver all the power you’d need for the tough everyday jobs you face on the job site or on the road. For heavy-duty performance and severe-duty service, go with the latest generation of the updated 6.7L Power Stroke® V8 Turbo Diesel, the most powerful ever in a Ford Super Duty® Class 3-5 chassis cab. And whether you power your Super Duty with gas or diesel, you have the Live-Drive Power Takeoff (PTO) Provision with Mobile Mode, available on gas models and standard on diesel.

All Super Duty® Chassis Cab models now feature a new standard Ford TorqShift® 10-speed automatic transmission, engineered to optimize drive ratios and improve shift performance. You can choose from five selectable modes — Normal, Tow/Haul, Eco, Slippery, Deep Sand/Snow — to match operating conditions.


The available Live-Drive Power Takeoff (PTO) Provision with Mobile Mode* and best-in-class diesel torque** lets you power an aftermarket snowplow, pump, compressor or other accessory. The PTO provision is available across the entire engine lineup. 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.

*Requires aftermarket power takeoff (PTO) accessory.

**Class 3-5 Conventional Chassis Cabs.

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.

Advanced Fuel Options


Compressed natural gas (CNG) and propane are advanced fuel options to unleaded gasoline, with the CNG/Propane Gaseous Engine Prep Package available on the 6.2L or 7.3L gas V8. What’s more, the CNG/Propane Package with the addition of the necessary upfits for bi-fuel capability enables the 6.2L or 7.3L V8 to run on either liquefied propane gas or unleaded gas. The 6.2L V8 is a flex-fuel engine, capable of running on E85 (85% ethanol, 15% regular gasoline); the available 6.7L Power Stroke® Turbo Diesel is B20-capable (20% biodiesel, 80% petrodiesel).
Advanced fuel options late availability. 7.3L gaseous prep package on F-450/F-550 only.


Some operating conditions, such as long idling, don’t generate enough engine heat for the diesel to automatically burn off soot in the diesel particulate filter. That’s where available Operator-Commanded Regeneration with Active Inhibit comes in. When the warning light comes on, pushing the activation button raises the exhaust temperature to burn off the soot, after which the exhaust temperature reverts to normal. The active inhibit feature allows delay of regeneration when the vehicle is sitting in a safe location not over combustible materials such as dry leaves or grass. Afterward, the driver can manually start the regeneration process. Recommended for commercial applications.
