GMC Sierra – Heavy Duty pickup of the 2500 and 3500 class: six- and eight-cylinder engines from 110 to 332 kW, 3.0 to 7.4-litre displacement, up to 6,150 kg gross weight

GMC has run the Sierra since 1987 as a standalone pickup model, technically related to the Chevrolet Silverado, and since 1999 as a fully separate range within General Motors; the Sierra family is built at, among other plants, Fort Wayne (Indiana), Flint (Michigan) and Silao (Mexico). The 1500, 2500 and 3500 numbers order payload class, the HD (Heavy Duty) suffix denotes the reinforced three-quarter- and one-ton versions with leaf-sprung rear axles, and trim levels such as SLE, SLT, AT4 and Denali range from work-focused to luxury specification.

The register lists 63 versions with 110 to 332 kW from six- and eight-cylinder engines of 2,990 to 7,441 cm³, unladen weights of 2,095 to 3,810 kg, gross vehicle weights of 3,500 to 6,150 kg and widths of 1,950 to 2,490 mm.

In the Heavy Duty class the Sierra competes chiefly with the Ford F-250/F-350 and Ram 2500/3500 on towing and payload capacity; typical uses are construction and agriculture, horse and boat transport, and commercial fleets, where the Duramax turbodiesel paired with the Allison automatic is valued as a tow vehicle.

When buying used, check the injection pump, turbocharger and exhaust aftertreatment (DEF) on Duramax diesels, cylinder deactivation and oil consumption on the petrol V8s, frame corrosion at the rear leaf-spring mounts generally, and wear on the hitch ball and trailer wiring on frequently used tow vehicles; parts run through the GMC and GM parts network.

What to check before buying

  • Check the hour meter against the service records — a replaced instrument is the most common gap.
