For 2019, General Motors released the medium-duty Silverado 4500/5500/6500HD, joining the Chevrolet LCF 3500/4500/5500 model line (derived from the Isuzu NPR). The successor to the previous Chevrolet Kodiak and GMC TopKick, the medium-duty Silverado was developed in a joint venture with Navistar; the latter company assembles the vehicle lines at its Springfield, Ohio facility.
