1. Our Ultimate Ranch Truck is big, and we're taking bets on just how much it will weigh when it's done. The truck's cumbersome weight and the power and torque output of the Powerstroke 7.3L turbo diesel forced us to go big! Dynatrac's Pro Series 80 was the perfect match for the truck. It will definitely stand up to the extreme trail conditions and the engine's 545 lb-ft of torque.
