The 2004 Chevrolet Silverado 2500 belongs to the first generation of the Silverado lineup. It comes in two formats: Heavy Duty (HD) and Light Duty (LD). The powerful pickups offer a diverse selection of engines, depending on trim, including a 6.0L V8 producing 300 hp and an 8.1L V8 generating 330 hp. A Duramax 6.6L turbo-diesel V8 option, paired with an Allison 1000 five-speed automatic, produces 300 hp and whopping 520 lb-ft of torque. Drivetrains include rear-wheel and four-wheel drive options. Notable features for this year include a comforting interior, digital control options, and a robust sound system with optional XM Satellite Radio. Its heavy-duty version stands out for towing capacity and overall durability. It's a benchmark for performance and reliability in the full-size pickup class.
