The International Paystar F-5050 6x6 was built by International Harvester from 1973 to 1987.

Model historyEdit

For Company history, see International Harvester.

The International Paystar 5000 line was a series of extra heavy-duty construction trucks intended for use as dump trucks, cement mixers, oil-field trucks, etc. The Paystar line replaced the M-series and the 210-230 series. It included various models with 4x4, 6x4, and 6x6 drive arrangements, powered by gasoline, mid-range diesel, and big-bore diesel engines from International and several other engine manufacturers. The Paystar F-5050 6x6 model replaced the M6123-50. It was designed for straight truck construction applications needing the traction of all-wheel-drive but not requiring the power of big-bore diesel engines.
