Vehicle Overview

The GMC Sierra 1500 and Chevrolet Silverado share the same platform, but the GMC product is often positioned as a more upscale offering. Mechanically, the trucks are the same. There might be slight differences in curb weight and payload, but they share the same powertrain and chassis components. There are five engines and five suspensions in the lineup.

The Sierra comes in regular, extended and crew cab forms. Standard (6-foot, 6-inch) and long (8-foot) cargo beds are available on regular and extended cabs, while the crew cab gets a short (5-foot, 9-inch) bed. All configurations are available in two- or four-wheel drive. The Sierra comes in four trim levels: Work Truck, SL (crew cab only), SLE and SLT. Most V-8 models are rated to tow around 9,000 pounds, but some models get more than 10,000 pounds with an enhanced trailering package.
