Chevrolet 5500HD
Chevrolet's medium-duty commercial workhorse — the 5500HD bridges the gap between one-ton pickup trucks and heavy commercial vehicles, offering Class 5 payload capability with Duramax diesel reliability.
Overview
The Chevrolet Silverado 5500HD is a Class 5 medium-duty commercial truck, sitting above the heavy-duty 1-ton pickup trucks and below Class 6 and above commercial vehicles. Launched in 2019, the 5500HD fills a critical commercial need for operators who have outgrown Class 3–4 trucks but don't require a full Class 6–7 vehicle.
Powered by the 6.6L Duramax turbo-diesel producing 350 hp and 1,085 Nm of torque, matched to the Allison 2100RDS 6-speed automatic transmission — a commercial-grade gearbox used across the medium-duty truck industry. The 5500HD is available as a chassis-cab only, designed for upfitting with flatbed, dump, service, tow, or specialty bodies.
In Azerbaijan, the 5500HD serves construction, towing, agriculture, and logistics businesses requiring substantial payload and versatile body configurations. The Duramax-Allison combination provides exceptional commercial durability.
