GMC Sierra 1500 Engines by Year

GMC's half-ton pickup took the Sierra name with the 1988 redesign. When a new generation arrived, the previous truck stayed on sale for a time as the Sierra Classic or Sierra Limited; the trims column marks those years.

Pick a year to see every engine offered that model year, with its code, rated horsepower and the trims it came in. Each engine links to its full specs.
