1992-1999 GMC Suburban: Overview

Vehicle Highlights

Suburbans moved to the platform of the then-current full-size General Motors C/K pickup trucks for 1992. Bodies measured slightly shorter and narrower. Cargo space and towing capacity increased. As before, Suburbans were sold in nearly identical form by GMC and Chevrolet dealers. Rear-wheel-drive models got a C designation, while 4-wheel-drive Suburbans were named K. A 1500 suffix indicates a 1/2-ton payload, whereas 2500 indicates 3/4-ton. A 210-horsepower 5.7-liter V8 continued as standard, but a heavy-duty 190-horsepower version went into some 2500-series models. Diesel V8 engines departed, but a 7.4-liter gasoline V8 was available. All Suburbans had a 4-speed automatic transmission and four-wheel antilock brakes. Part-time Insta-Trac 4WD had automatic-locking hubs. Suburbans could be equipped to seat up to nine passengers. The standard configuration consisted of four side doors and two swing-open rear doors. A tailgate with top-hinged rear window was optional.
