The Lariat and the King Ranch are some of the most distinctive F-150 trims on the market, trucks with unique personalities and even more impressive capabilities. The Lariat has a smaller engine, a 2.7L EcoBoost V6 with a corresponding smaller towing capacity, than the King Ranch, which comes standard with a 5.0L V8 engine. The King Ranch's list of features is also longer, with more tech options coming standard than on the Lariat.
