1950-1959

1950 - The Mack L series heavy-duty trucks of the 1940-1956 era exhibited clean, timeless styling and proved extremely popular. Certain models in this series combined many aluminum components with the more powerful engines to satisfy the long distance hauling needs of West Coast operators. Some 35,000 Mack L models graced the highways in their day.

The 1950s brought significant product advancements from Mack, including the G, H and B models. The G series featured an all-aluminum cab for light weight and the ability to haul big payloads, especially in West Coast applications. The H series, dubbed the "Cherry Pickers" for their very high cabs were designed with a short bumper-to-back of cab dimension to accommodate 35 foot trailers within 45 overall legal limits.

The B series, introduced in 1953, was surely one of Mack's most successful and popular products. Its pleasing, rounded appearance set a new styling standard for trucks, as did the wide range of model variations offered. There are B models still in active service today, part of the 127,786 built through 1966. The year 1953 also marked the introduction of the famous Thermodyne open chamber, direct-injection diesel engine, which established Mack's tradition of leadership in diesel performance and fuel efficiency.
