5500XD

This Chevrolet medium-duty nameplate first appeared for the 2017 model year as part of the brand’s Low Cab Forward commercial truck lineup. The 5500XD was positioned as the heavier-duty diesel step within that cab-over family, aimed at vocational buyers who needed a chassis cab with a higher gross vehicle weight rating than the lighter versions. Chevrolet’s official commercial pages still list the model today, indicating that it remains in production rather than having ended and returned later. Over time, the vehicle has continued to serve the same basic role: a work-focused, cab-over commercial truck for upfitting into delivery, utility, service, and other specialized applications. It is part of Chevrolet’s modern commercial-truck strategy rather than a revived historic nameplate, and it has followed a single continuous production run since its introduction.
