Commanding Power and Allison Transmission Reliability
Performance in the 2026 Sierra 2500 HD SLT is defined by the legendary 6.6L Duramax Turbo-Diesel engine, which provides a massive 975 lb-ft of torque for maximum pulling power in Morton. This engine is paired with the heavy-duty Allison 10-speed automatic transmission, ensuring that power is always delivered smoothly and efficiently to the wheels even under extreme loads. For those who prefer a gas engine, the 6.6L V8 is also available, providing reliable power for daily tasks and a standard towing capacity that exceeds the needs of most Morton owners. With a maximum conventional towing capacity of 20,000 pounds, this truck is ready to haul anything from industrial machinery to large luxury campers across Illinois.
