Chevrolet Sierra – collective page of the Sierra trim line on GM's shared pickup chassis: Pickup Sierra, Sierra 1500, Sierra Classic and Sierra Grande, throughout eight-cylinders of 5,700 to 7,325 cm³
This page gathers pickups carrying the Sierra name, built on General Motors' shared full-size pickup chassis. Sierra and Sierra Grande ran there from the 1970s as a trim line available across both of the group's sales channels, before GMC made Sierra its own standalone pickup range in 1987; the models recorded here – Pickup Sierra, Sierra 1500, Sierra C, Sierra Classic 15 and Sierra Grande Pick-up – show this transitional period, when Sierra still appeared as an additional designation on the shared chassis.

The register lists here 5 versions, throughout with eight-cylinders and a displacement of 5,700 to 7,325 cm³, unladen weights from 1,810 to 2,920 kg, gross weights from 2,170 to 3,500 kg and widths from 1,920 to 2,450 mm.
The large displacement of up to 7,325 cm³ points to the big-block engines with which General Motors equipped its half-ton pickups in the 1970s for heavy towing and the North American market, where they competed with Ford and Dodge for dominance in the pickup segment.
On used examples of these big-block eight-cylinders, the condition of the carburettor, ignition distributor and cooling system, rust on the frame, load bed and wheel arches, the condition of the clutch or automatic transmission, and brakes and axle suspension matter; parts run through the wide North American GM aftermarket.
