How much does a 1980 Chevy K20 weigh?

A typical curb weight for a 1980 Chevrolet K20 is around 5,000 pounds, with a gross vehicle weight rating in the mid to upper 7,000s—leaving a payload window of roughly 1,800 to 2,500 pounds depending on configuration.


Context and what the numbers mean


For collectors, drivers, and restorers, the weight of a 1980 K20 matters for towing, payload capacity, and road handling. The K20 is a 3/4-ton, four-wheel-drive pickup built on the C/K platform, with variations in bed length, cab configuration, engine, and options that influence curb weight and GVWR.


Common weight ranges by configuration


The following ranges reflect typical factory curb weights for common engine and drivetrain setups, excluding payload, cargo, and passengers.



  • 350 cubic inch V8 with 4x4 and manual transfer case: approximately 4,900–5,100 pounds

  • 350 cubic inch V8 with 4x4 and automatic transmission: approximately 5,000–5,200 pounds

  • Big-block V8 options (e.g., 400/454) with 4x4: approximately 5,100–5,300 pounds


Note that wheelbase (short vs. long bed), cab options, and added equipment (AC, power windows, heavy-duty suspension) can shift curb weight by hundreds of pounds in either direction.


GVWR and payload considerations


Alongside curb weight, the GVWR defines how much total weight the truck can carry. For 1980 K20 models, GVWR generally sits in the mid to upper 6,000s to around 7,400 pounds, depending on equipment and axle gearing. This yields a payload capacity commonly in the range of roughly 1,800 to 2,500 pounds when the truck is loaded to its rated limit.


Summary


In short, a 1980 Chevy K20 typically weighs about 5,000 pounds as a curb weight, with a GVWR around 7,000 pounds and payload capable of roughly 1,800–2,500 pounds depending on configuration. For precise figures, check the truck’s VIN data plate, the original sales brochure, or a dealership specification sheet for the exact build.
