This gas-powered low cab forward commercial truck nameplate was added for the 2024 model year as part of Chevrolet’s modern Low Cab Forward lineup. It brought a gasoline alternative to the medium-duty cab-over range, paired with Chevrolet’s 6.6L V8 and offered in work-oriented cab and chassis configurations for commercial upfit use. Positioned above the smaller low cab forward gas models and alongside heavier diesel variants, it was aimed at fleets, delivery, utility, and other vocational buyers that need tight maneuverability and straightforward body integration.
The low cab forward family itself is Chevrolet’s contemporary continuation of the cab-over concept in the U.S. market, emphasizing visibility, short overall length, and easier access for body builders. The 4500 HG became part of that family when Chevrolet expanded the gasoline lineup for 2024, and it remained in production through at least the 2026 model year. Unlike Chevrolet’s older medium-duty conventional trucks, this nameplate belongs to the modern Low Cab Forward era rather than the discontinued Kodiak/TopKick lineage.
