In line with the previous generation, while designed with its own heavier-duty chassis, to lower the costs of tooling, the cab of GMT530 trucks was derived from the GMT400 C/K pickup (introduced in 1988). As before, two-door and four-door configurations were offered; a raised-roof cab became optional during the 1990s. Over its thirteen-year production run, the GMT530 platform underwent relatively few changes; as airbags were not required in medium-duty trucks, the 1988-design interior was retained through the entire production run. For 1995, GM replaced the Kodiak and TopKick badging with C4500-C8500 model names, bringing the medium-duty trucks in line with the rest of the C/K naming convention. As an option, a lower-profile "aerodynamic" hood became an option (not offered on severe-service or school bus applications).
