Dominant Power and Allison Durability
Performance in the 2026 Sierra 2500 HD Pro is anchored by the standard 6.6L V8 gas engine, providing 401 horsepower and 464 lb-ft of torque for reliable daily hauling. For businesses in Morton that need even more muscle, the available 6.6L Duramax Turbo-Diesel delivers a massive 975 lb-ft of torque, making it a champion for towing heavy trailers across Illinois. Both engines are paired with the heavy-duty Allison 10-speed automatic transmission, which is engineered to maintain consistent power delivery even under extreme loads. This powertrain configuration allows the Sierra 2500 HD to tow up to 22,500 pounds when properly equipped, providing the strength needed for the most demanding commercial tasks. Standard features like StabiliTrak with Trailer Sway Control and a heavy-duty locking rear differential help you maintain command of your load on the varying road conditions of central Illinois. This mechanical combination is built for maximum uptime, helping you keep your business moving forward with absolute confidence. It is a powertrain that focuses on delivering results in the real world every single day.
