When it comes to heavy-duty diesel trucks, three nameplates carry the “2500” designation: the Chevrolet Silverado 2500HD, GMC Sierra 2500HD, and Ram 2500. Each brings its unique blend of power, luxury, and practicality to the table. For buyers looking to invest in a truck that can handle the toughest jobs while offering reliability and value over the long haul, the decision often comes down to the details. Let’s compare these trucks based on pricing, warranties, residual values, and their perceived quality over time to see how they stack up.

Powertrain and Performance

• Chevrolet Silverado 2500HD and GMC Sierra 2500HD: Both trucks share the 6.6L Duramax Turbo Diesel V8 engine, delivering 470 horsepower and 975 lb-ft of torque. Paired with the renowned Allison 10-speed automatic transmission, this combination offers excellent towing capacity—up to 22,500 pounds in properly configured models. The Duramax engine is celebrated for its consistent performance and durability.
• Ram 2500: Equipped with the 6.7L Cummins Turbo Diesel I6 engine, the Ram 2500 offers 370 horsepower and 850 lb-ft of torque in its standard output configuration. While these numbers are lower than the Duramax, the Cummins is revered for its longevity and smooth power delivery. For even more power, the High Output Cummins (available on limited trims) pushes the torque beyond 1,000 lb-ft, making it a towing powerhouse.

Winner: The Silverado and Sierra lead in raw horsepower and torque, but the Cummins engine’s reputation for longevity is unmatched.
