The 2006 Chevrolet Silverado 2500HD represents the early years of the model's second generation. A stalwart of the heavy-duty truck segment, it's offered with a robust engine lineup including a 300-hp 6.0L V8 and the famed Duramax 6.6L turbo diesel V8 cranking out 360 hp and a monstrous 650 lb-ft of torque. Paired with these engines is a 4-speed automatic, a 5-speed manual, or an optional Allision 1000 6-speed automatic. Rear-wheel drive comes standard, with an optional four-wheel drive across all five trims - Work Truck, LS, LT1, LT2, and LT3. The Silverado 2500HD is appreciated for its towing and hauling capabilities, underpinned by features such as an optional heavy-duty trailering equipment. Infotainment technology is more basic in this model year, with AM/FM stereo being standard and options for BOSE sound system, and an in-dash 6-disc CD changer.
