The Silverado 2500 HD
Heavy duty, without apology.
The heavy-duty Silverado exists for the loads a light-duty truck turns away. High Country specification pairs that capability with a cabin of quilted leather, wood décor and a 13.4-inch display, so the working end of the truck never dictates how it feels to drive.
A load bed with a plan
The Durabed offers 1,968 litres in Standard Bed form, with a Multi-Flex Tailgate giving six load and access positions and a Bed View Camera for hitching up alone.
Comfort at working scale
Premium perforated and quilted leather, heated front and outboard rear seats and power-retractable assist steps make a 6.4-metre truck easy to live with every day.
Silverado HD is the truck American ranches, trades and towing businesses reach for when weight is the deciding factor. Bringing it to the UK through GMSV means the same hardware arrives with UK homologation, servicing and a warranty behind it.
