Key Features

7.3L V8 Gas Engine

7.3L 2V DEVCT NA FPI V8 Gas Engine

The class-exclusive* 7.3L V8 gas engine is Built Ford Tough,® featuring a gas V8 output of 335 hp at 5,500 rpm and torque of 468 lb.-ft. at 3,750 rpm.** This engine has the largest displacement in its class and features an overhead valve architecture that generates power low in the rev range to help get heavier loads moving with confidence. It also features a variable-displacement oil pump, extra-large main bearings, a forged-steel crankshaft for durability and piston cooling jets to help manage temperatures under heavy load.

*Class is 6–7 Conventional Chassis Cabs.

**When properly equipped. Horsepower and torque ratings are independent attributes and may not be achieved simultaneously.

Ford TorqShift® Heavy-Duty 6-Speed Automatic Transmission

The Ford TorqShift® HD 6-Speed Automatic Transmission is specially designed with a three-plate/two-stage torque converter, strengthened gearsets and extra pinion gears to handle the heavy demands of the 7.3L V8 gas engine. The SelectShift® feature has two modes: Progressive Range Select, which limits the range of gears to lock out overdrive, and full manual control. Another useful feature is Tow/Haul: on an uphill, it selects the gear that minimizes gear hunting; on a downhill, it prevents upshifting and increases in speed, reducing reliance on brake pressure to slow down. And the TorqShift offers the available live-drive Power Take-Off (PTO) provision with stationary and mobile modes.
