With gas prices at record highs, Ford's heaviest and biggest trucks, the F-350 models and F-450, are surpassing all sales expectations.

The decked out Lariat and King Ranch variations of the F-350, as well as the F-450, are going gangbusters, with the King Ranch up 53-percent over last year, while the Lariat is up 30-percent. Overall, both models are leading their segment. With options topping $17,000 and sticker prices exceeding $60,000, the truck's decent sales are likely a breath of fresh air to the incentive-prone automaker.

Ford has more to brag about in its lighter trucks -- the F-250 also continues to be the top seller in its segment, and the F-150 historically has been one of Ford's most important vehicles behind the Taurus, set to relaunch this fall.
