The current GMC Sierra 1500 can tow up to 4,445 kg braked. Figures below are the strongest variant in each generation — lighter trims and engines tow less.
| Years | Braked | Unbraked |

Towing capacity is the manufacturer-rated maximum for the model's strongest variant in each generation, not an average across trims — a base engine will tow less than the figure shown. Cars with an implausible source-data towing figure relative to their own kerb weight are excluded rather than shown with a guessed correction.
