The 2017 F-150 STX is priced at $35,615.
The 2017 F-250 STX starts at $34,910 and the F-350 STX is priced at $36,080. All prices include a $1,195 destination charge.
This is the first time the F-Series Super Duty is offered with the STX appearance package.
"STX is for customers who want the utility of an F-Series truck in a stylish, well-optioned package at a competitive price," said Doug Scott, Ford truck group marketing manager, in a statement.
The F-150 STX is positioned between the XL and XLT models and is available with the 2.7-liter EcoBoost four-cylinder engine, 5.0-liter V8 engine and the 3.5-liter EcoBoost V6 engine.
The package adds a number of items, including 20-inch machined-aluminum wheels, a black billet-style grille and black sport cloth seats.
The Super Duty STX package is available with either the 6.2-liter V6 gas engine or 6.7-liter V8 Power Stroke diesel engine. It can be ordered on all Super Duty cab configurations.
Upgrades include a bright chrome grille, unique aluminum wheels and chrome front-and-rear step bumpers.
Edmunds says: The STX appearance package should hit the sweet spot for value-minded truck buyers seeking a custom look at an affordable price.
