Sierra Other models

The register lists 8 versions here with a consistently recorded displacement of 6,162 cc across eight cylinders, kerb weights from 2,423 to 2,757 kg, a gross vehicle weight of 3,221 kg, lengths from 5,890 to 5,910 mm and a width of 2,060 mm.

The Sierra 1500 competes directly in the North American full-size pickup market with the technically related Chevrolet Silverado as well as the Ford F-150 and Ram 1500; Denali and AT4 mark the model's two positionings between premium comfort and off-road capability, and both trims rank among the best-equipped versions in the GMC line-up.

When buying used, these large-displacement V8 pickups call for checking the condition of the load bed and towbar, wear on axles and brakes under heavy loads, the maintenance history of engine and transmission, and on AT4 models the condition of off-road tyres, skid plates and the locking differential; parts run through the GMC dealer network.
