The 2025 Silverado 3500 HD comes standard with a powerful 6.6L V8 Gas engine. If you need extra muscle, Chevrolet offers an optional DURAMAX 6.6L turbo-diesel V8 engine. Both pair with an Allison 10-speed automatic transmission and an automatic locking rear differential.

Towing and hauling capability is exceptional: the truck boasts a maximum towing capacity of 36,000 lbs and includes an integrated trailer brake controller for safe control. The Digital Variable Steering Assist dynamically adjusts steering based on speed and road conditions, giving you comfort whether cruising empty or loaded.

New for 2025, select trims feature an available Trail Boss package with an off-road suspension and 20-inch wheels, plus an available Suspension Package designed to optimize handling and ride quality while towing. The Autotrac 2-speed transfer case with push-button controls rounds out the capability.
