1999 GMC K3500 Review

Soon to go down as a classic.

Reviewed by Automotive on


The 1999 GMC K3500 is a four-wheel drive full-sized pickup truck manufactured by General Motors. This truck is part of the C/K Series, an old series of trucks that has been in production since 1960. The C/K Series is currently being phased out for the more modern Silverado line of pickups. Despite its outdated design, the K3500 and other C/K Series trucks are quite a popular among those who want strong workhorses.

The Range

Body Styles: regular cab, extended cab, crew cab
Engines: 5.7-liter V-8, 7.4-liter V-8
Transmissions: four-speed automatic, five-speed manual
Models: GMC K3500 SL, GMC K3500 SLE, GMC K3500 SLT

What's New

The C/K Series trucks are almost at the end of its production life, but the 1999 GMC K3500 is still getting some revisions for this year. This model year gets some new internal components and new seals for the automatic transmission. The engine cooling system has been improved, and so has the durability of the starter motor. The 1999 GMC K3500 will be available in three new exterior colors.


The 1999 GMC K3500 is available in three body types: regular cab, extended cab, and crew cab. Each body type comes with the choice of either a 6.5-foot cargo bed or an eight-foot cargo bed. The styling of the 1999 GMC K3500 remains the same as its previous model year, with the box-like shape that is reflective of the decades-old C/K Series big trucks. The last major revision of the exterior of the K3500 can be traced back to 1994, when a new front fascia was used.


The 1999 GMC K3500 may be a heavy-duty hauler, but General Motors has not forgotten to add some creature comforts inside the truck. The truck interior is available in three choices of upholstery depending on the model chosen: vinyl, which is the standard, cloth, or even leather. The front of the truck may be fitted with two bucket seats or a three-place bench, depending on the number of people required to be seated. However, the middle spot on the bench seat tends to be a little small, so three adults would be hard pressed in the front seat of the truck. Moreover, the seats themselves are flat and unsupportive, but they do provide comfort on long trips. Like any other big truck of the C/K Series, the 1999 GMC K3500 also has quite a wide rear bench on its extended cab models. However, the seatback tends to be uncomfortably vertical, and knee room is not enough to keep the occupants comfortable.

Performance & Handling

The 1999 GMC K3500 is available with a 5.7-liter V-8 engine as standard, delivering 255 horsepower and 285 lb-ft of torque. The truck is also available with an optional 7.4-liter V-8 engine that delivers 290 horsepower. The base 5.7-liter engine is among the most powerful base engines used in the full-sized truck segment. Not only is it refined, but it also provides enough power to easily get moderate towing and hauling tasks completed. However, if a heavy-duty model like the K3500 is being considered, then the best option is the bigger 7.4-liter engine, which delivers enough power for any hauling and towing job without losing the refinement of the base engine.

The 1999 GMC K3500's expected bounce with an empty cargo bed is proportional to the payload capacity. Therefore, with one of the highest payload capacities in the series, the K3500 suffers from quite a bumpy ride. On a positive note, the truck does offer good and stable steering response and the braking response is quite good, too. The dashboard uses a lot of low-grade interior materials, but it does not come as a complete surprise. Despite its lack of quality, the overall layout of the climate and audio controls are quite good.


There are no crash test results available for the GMC K3500 at present.
