context_page_description: The Ford Super Duty is a series of trucks manufactured by Ford Motor Company. Introduced in 1998 for the 1999 model year, the F-Series Super Duty trucks marked the addition of a heavy-duty pickup to the Ford F-Series range with the new versions of the F-250, F-350, and F-450 pickups, while the previous 1987–1997 F-Super Duty chassis cabs were replaced by the F-450 chassis cab and F-550 Super Duty.
  The Super Duty trucks utilize a distinct chassis from the lighter F-150, with heavier-duty chassis and suspension components to allow for higher payload and towing capacities; additionally, the product line continued the use of Ford PowerStroke diesel engines. With a GVWR over 8,500 lb, Super Duty pickups are class 2 and 3 trucks while chassis cab trucks are class 4 and class 5. The F-Series Super Duty has been used as the base chassis of the Ford Excursion full-size SUV.
  Ford F-250 to F-550 Super Duty trucks are assembled at the Kentucky Truck Plant in Louisville, Kentucky, while medium-duty F-650 and F-750s are assembled at Ohio Assembly in Avon Lake, Ohio.
context_section_description: For the 2005 model year, the Ford Super Duty trucks were given exterior and interior updates. For the exterior, a new grille, front bumper, and headlights were introduced alongside the introduction of a locking tailgate for all pickup trucks. Under the skin (with thicker frame rails), updated Triton gasoline engines were introduced with higher engine output and larger alternators; in response to the increased power, all trucks were given 4-wheel disc brakes (with two-piston calipers). To accommodate the larger brakes, 17-inch wheels became standard, with 18-inch wheels optional (on single rear-wheel trucks); forged Alcoa wheels were an option. The long-running Twin I-Beam front suspension continued on two-wheel drive trucks.
  To the interior, several changes were made to improve functionality for end-users. Along with the addition of a driver-side glove compartment, the truck added the option of dashboard-mounted auxiliary switches (for owners who fit equipment such as snowplows, winches, and auxiliary lights); these are switches that were typically user designed. For users that tow, a new option was Ford TowCommand, a Trailer brake controller built into the dashboard, allowing it to integrate with the ABS system and engine computer from the factory.
