The International Harvester S-Series was a medium-duty truck line made by International Harvester from 1978 to 1992. It served as a gradual replacement for the International Harvester Loadstar, which was last produced in 1979. Like the Loadstar, the S-Series trucks were commonly used for local delivery vehicles, and for school buses.
Most of the components were carried over into a new line of medium duty trucks with a redesigned hood and interior in 1991, and an update of the interior in 1995 until the model's discontinuation in 2001.
First Generation[]
In April 1977, International Harvester unveiled the medium-duty S series at an event at the New Orleans Superdome.[1] The initial lineup consisted of heavier-duty 2200, 2500, and 2600 models (28,000-45,000 lb gross vehicle weight rating - GVWR), replacing the Fleetstar. In the summer of 1978,[2] lighter-GVWR models (replacing the Loadstar) were released for sale. The 21 models of the full lineup had a high degree of parts interghangability; this standardization helped lower the number of parts used by 30%.[3]
Following the discontinuation of the IHC pickup-truck line in 1975, the S series was designed with a model-specific cab, replacing the pickup-truck cab used for the Loadstar (designed for the 1957 A series). More vertically oriented than its predecessor, the design was much wider, as well. To lower maintenance costs, all windows in the cab were designed with flat glass, including the windshield. Similar in style to the tilting hood introduced for the Loadstar in 1972, all S-series trucks were given a tilting fiberglass hood.
The S series was produced throughout the 1980s, largely unmodified, and 1987 marked several changes to the S-series trucks. To reflect the corporate transition of the company from International Harvester to Navistar International, S-series trucks received changes in their badging (alongside all International vehicles). On the grille, the word "International" across the top of the grille was replaced by a red Navistar "diamond" logo alongside "International" in red at the bottom left of the grille. Inside, the IHC "tractor" logo on the steering wheel was replaced by a Navistar diamond logo. In a major shift, for 1987, International became the first truck manufacturer to produce a medium-duty product line powered exclusively by diesel engines.
Models[]
Originally intended to use the International Tristar nameplate, the S series consolidated the aging Loadstar and Fleetstar trucks under a single product line. Tandem-axle (6x4) versions of the S series were named F-series trucks.[4]
Class 6 trucks[]
The S1600, S1700, S1800, and S1900 were introduced in 1979 (after-International Harvester Auto Wagon, International F-Truck, International Model S, International Six Speed, International Harvester A-3, International Harvester B-3, International C-30 Truck, International CS-30 Truck, International Harvester D-Series, International Harvester K-6 Modified as 1941 Dodge W-Series, International Harvester KB-6 Modified as 1941 Dodge W-Series, International Harvester L-160, International Harvester R-160, International Harvester Loadstar (1962-1971), and International Harvester Loadstar (1972-1978))/(after-International Harvester Auto Wagon, International F-Truck, International Model S, International Six Speed, International Harvester A-3, International Harvester B-3, International C-30, Truck, International CS-30 Truck, International Harvester DS-30 Truck, International Harvester K-6 Modified as 1941 Dodge W-Series, International Harvester KB-6 Modified as 1941 Dodge W-Series, International Harvester L-160, International Harvester R-160, International Harvester S-160, International Harvester A-160, International Harvester B-160, International Harvester Loadstar (1962-1971), and International Harvester Loadstar (1972-1978))/(after-International Harvester Auto Wagon, International F-Truck, International Model S, International Six Speed, International Harvester A-3, International Harvester B-3, International C-300 Truck, International CS-300 Truck, International Harvester DS-300 Truck, International KS-6 COE, International KBS-6 COE, International Harvester L-160 COE, International Harvester R-160 COE, International Harvester S-160 COE, International Harvester AC-160, International Harvester BC-160, International Harvester Loadstar (1962-1971), and International Harvester Loadstar (1972-1978)). Replacing the International Harvester Loadstar model line, the model was produced in a number of configurations, with single and tandem rear axles, 4x4/6x6 drive options, and gasoline and diesel engines. The S-1800 and S-1900-were produced as both truck tractors (for semitrailers) and straight trucks, while the S-1700 and S-1800 were used in the production of International Harvester bus chassis (primarily for school-bus use), Competitors include Ford F-600/F-700/F-800 (1980-1994) and Chevrolet Kodiak (1981-1989).
Class 7-8 trucks[]
Introduced in 1978 as the replacement for the Fleetstar, the S2100 and S2200 were joined by the severe-service S2500 and S2600, slotted below the International Paystar 5000. Configured primarily as tractors, the S2100s were fitted with a sloped hood. To accommodate larger-bore diesel engines under a standard-length hood, the S2200 was fitted with a widened cab (distinguished by a two-piece windshield).
In 1982, the S2300 was introduced; the model line was essentially an S2100 with International diesel engines replaced with Cummins-sourced powertrains.[5]
