GMC Sierra – collective page of the GMC pickup with V8 engines from 5.0 to 6.2 litres, Denali, Grande and SLE trim lines, 2,112 to 3,014 kg unladen weight, up to 3,500 kg gross weight
This collective page gathers versions of the GMC Sierra, the pickup model of General Motors' GMC commercial brand. The Sierra is the technically close sister of the Chevrolet Silverado and has been built as a full-size pickup in North America since the 1980s; the models captured in the register, SIERA, SIERA 2500 HD, SIERA DENALI, SIERA GRANDE and SIERA SLE, show the range of trim lines, from the base version through the heavy 2500 HD class to the luxury Denali trim.

The register lists here five versions with V8 engines of 5,000 to 6,162 cm³, unladen weights from 2,112 to 3,014 kg, gross weights from 2,540 to 3,500 kg and widths from 1,920 to 2,050 mm.
Alongside the Ford F-150 and the Ram, the Sierra is among North America's best-selling vehicles and is used there both commercially as a work vehicle and privately; in Europe examples appear mainly as imports and in towing use.
On a used example, check the condition of the V8 engine and its timing chain, rust on the frame and wheel arches, wear of the automatic transmission and rear axle under trailer load, and for US imports the technical approval for European roads and the condition of brakes and tyres under the heavy trailer loads typical of US pickups, plus rust on the bed floor and tailgate hinges; parts run through GM and independent US-import dealers.
