About the 2012 Chevrolet Silverado 3500
Second-generation Silverado HD (GMT900); second model year after the major 2011 heavy-duty chassis and powertrain overhaul, with a capability-focused structural update for 2012.
Chevrolet positioned the Silverado 3500HD as its one-ton pickup for demanding towing, hauling and commercial work. Its core strengths were a fully boxed high-strength-steel frame, single- or dual-rear-wheel configurations, multiple cab and bed layouts, V8 power and heavy-duty trailering hardware. Compared with rivals, it emphasized high maximum ratings while also delivering accurate steering and a more controlled, quieter towing experience than traditional work trucks.
The 2012 lineup ranges from the job-focused Work Truck to the more convenient LT and comfort-oriented LTZ. Work Truck has durable basics and heavy-duty cooling, while LT adds power accessories and heated extending trailering mirrors. LTZ brings heated leather-appointed power seats, dual-zone automatic climate control, and Bose audio.
