5.4 TIMING CHAIN REPLACEMENT SERIES

The SuperCab configuration of the Super Duty marked the introduction of two standard rear-hinged doors on the extended cab, a feature also adopted by the F-150 and Ranger/ Mazda B-Series for 1999. The Super Duty trucks were produced with three cab configurations-a two-door regular cab, 2+2 door SuperCab, and four-door crew cab. Prior to the release of the Super Duty series, the previous-generation F-250HD and F-350 carried over for 1997 (alongside a separate F-250 light duty based upon the tenth-generation F-150).īeginning production in January 1998 for the 1999 model year (1998 hiatus), the Ford F-Series Super Duty consisted of the F-250 pickup truck, F-350 pickup truck and chassis cab, and introduced the F-450 and F-550 chassis-cab trucks (see below). By expanding the model line into two separate but related platforms, the inevitable compromises inherent in offering a wide range of load-carrying capacities were avoided. To appeal towards commercial and fleet buyers and owners who tow, the F-250 and F-350 were developed as a separate, dedicated heavy-duty truck platform (in place of using one platform for all of its trucks). While still functioning as a full-size pickup, the F-150 adopted car-like aerodynamics and convenience features to expand its appeal among consumers.

In response to the changing demographics of pickup truck buyers during the 1980s and 1990s, as part of the redesign of the F-Series for the 1997 model year, the model family began a split into two model families, introducing the 1997 Ford F-150 as the first of two distinct F-Series lines. In 1987, Ford revitalized the name as a Class 4 truck badged as the 'F-Super Duty.' Manufactured solely as a chassis-cab vehicle, it was slotted between the F-350 and F-600 at the time, and was offered either with a 7.5L gasoline V8 or a 7.3L diesel V8. Though its poor fuel economy proved uncompetitive against the increasing popularity of diesel engines, the durability of the Super Duty V8 kept the engine in production until 1981.

Alongside the Ford C-Series and H-Series cabovers, the N-Series conventional adopted the Super Duty name. To showcase the engine launch, the 'Big Job' conventional truck variants of the F-Series were rebranded as Super Duty, a name added to other Ford trucks as well. The largest-block V8 engines ever built by Ford Motor Company, the Super Duty engines were the largest mass-produced gasoline V8 engines in the world (for road-going vehicles). In 1958, Ford introduced the Super Duty engine family as big-block V8 engines for trucks, offered in 401, 477, and 534 cubic-inch displacements. Prior to 2016, medium-duty trucks were assembled in Mexico under the Blue Diamond Truck joint venture with Navistar International.īackground Previous use of name The Super Duty trucks and chassis-cabs are assembled at the Kentucky Truck Plant in Louisville, Kentucky, and at Ohio Assembly in Avon Lake, Ohio. The Super Duty pickup truck also served as the basis for the Ford Excursion full-sized SUV. The model line also offers Ford Power Stroke V8 diesel engines as an option.įord also offers a medium-duty version of the F-Series (F-650 and F-750), which is sometimes branded as the Super Duty, but is another chassis variant. With a GVWR over 8,500 lb (3,900 kg), Super Duty pickups are Class 2 and 3 trucks, while chassis-cab trucks are offered in Classes 3, 4, 5, and 6. The heavier-duty chassis components allow for heavier payloads and towing capabilities. Rather than adapting the lighter-duty F-150 truck for heavier use, Super Duty trucks have been designed as a dedicated variant of the Ford F-Series. The F-250 through F-450 are offered as pickup trucks, while the F-350 through F-600 are offered as chassis cabs. Slotted above the consumer-oriented Ford F-150, the Super Duty trucks are an expansion of the Ford F-Series range, from F-250 to the F-600.
