International Paystar
The International Paystar is a series of trucks that was manufactured by International Harvester and its successor, Navistar International. Produced from 1972 to 2016 across three generations, the Paystar replaced the long-running 210/230 and M-series. Developed for both on and off-road use, the Paystar was the largest commercially-marketed product range sold by International, intended for vocational applications. For 2017, the Paystar underwent a substantial redesign, becoming the International HX series.
History
The PayStar was introduced by International Harvester in January 1972 as a construction-specific version of the conventional Transtar.From 1972 through 1980, it was offered in two ranges: the 5050 with mid-range engines and the 5070 with heavy duty engines. Available in 4×4, 6×4, and 6×6 configurations, they were usually straight trucks but most offered trailer brake options. Semi tractors were also available.
