Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 1981 K2500.
The 1981 GMC Truck K2500 opens a complaint dataset that runs from 1990 through 1996, anchoring the earliest model year in a record where filings range from a single report in 1992 to twenty-five reports in 1996. For a researcher mapping the model's long-term record, that range is the working scale of the page — a more-than-twentyfold spread between the quietest and noisiest years, with the 1981 build sitting as the first reference point rather than the most-complained-about entry. Positioned at the head of the K2500's tracked history, this model year frames the period in which owners actually surfaced issues, and the contrast between the 1992 floor and the 1996 peak gives every later model year a clear benchmark against which to read.
