Chronology
Successor	International Harvester R-Series

The International Harvester L Series Trucks were introduced by International Harvester in fall 1949 as the replacement for the KB-Series and ran the gamut from light pickup trucks and delivery vehicles to full size tractor trailers. Electric wipers, a radio, and a clock were optional.^[1] International would continue to produce the line until 1952 when it was replaced by the R Series.

Development

Heavier versions such as the L-150 to L-185 models had taller bodywork to accommodate a bigger engine, beefier chassis, and larger wheels. To hide this in appearance, they receive an extra, full-width chrome grille bar underneath the other two and the headlights. The L-190-L210 models had a longer, narrower hood and taller grille than all the smaller models, surrounded by oversized fenders. These trucks were a different look although they have the same cab as the smaller trucks. Of the pickup-type bodies, these were available in 6 ft and 8 ft lengths. On L-130 models, a 9-1/2 ft long pickup bed of same design was available and accommodated dual rear wheels. Two different styles of IH factory flatbeds with removable sides were also available for sizes up to L-180. Other bodies were designed around the basic truck chassis of each series, such as the "Metro" LM120-122 and LM150-152, the "bread trucks" used by bakeries or laundries for example. They hardly resembled the L-Line. The LB-140 Milk Delivery truck was also an oddity with its looks and revolutionary semi-automatic clutch, however it had the L-line face. The LC160-162 and LC180-182 cab-over trucks, or cab-forwards" as they were called back then, were another oddity of their own.

The first of the marketing names

The "Schoolmaster" : L-153, L-163, L-173, L-183, and L-193. The L-193 bus had the same nose style as the L190-up trucks.
The "Loadstar" : First introduced in the L-Line, as the L-164, L-174, L-184, L-194, and L-204. It was the model with the heaviest capacity within each series. The "4's" were the only ones to have the "Loadstar" decal on the dash.
The "Roadliner" : First introduced in the L-Line, assigned to the L-165, L-175, L-185, L-195, and L-205. The Roadliner was IH's specific "premier" tractor truck model "loaded" with comforts and work-ready, which means not all tractors are the "5's." It was common to see basic L-190 tractors or L-183 tractors, for example. The customer typically ordered the cab & chassis package they wanted and had a body or 5th-wheel installed elsewhere.

Mining, construction, & industrial

To further bolster its presence alongside IH's own massive line of heavy construction equipment and meet highway weight limits, the LF-170, LF-190, and LF-210 series was built. These were tandem-axle 6x4 trucks for hauling heavier loads than their 4x2 counterparts. For example, the GVW of a L-194 is 25,500 vs the 38,000 of the LF-194.

Engines

The lighter duty versions were equipped with the all-new OHV "Silver Diamond" engines in two different sizes (220cid & 240cid), while the medium-duty versions retained the older 269 ci "Blue Diamond", also an OHV engine, although it was now called the "Super Blue Diamond" after some detail improvements.^[2] The BD-269 has the same peak power as the smallest, but offers more torque, at 222 lb·ft (301 N·m) versus 192 lb·ft (260 N·m) for the Silver Diamond 240.^[3]
