1999 GMC K2500 Review

A powerful workhorse truck.

Reviewed by Automotive on


The GMC K2500 is a full-size, heavy duty pickup truck manufactured by General Motors. It has four-wheel drive and is one of the largest vehicles that the company makes. A large 255 horsepower engine provides plenty of power to haul goods and tow as much as five tons. In 1998, GMC introduced the Autotrac four-wheel-drive system to the K2500. The system has been compared to Ford’s Control-Trac system in the Ford Expedition and automatically shifts from two-wheel drive to four-wheel drive.
