The 2025 Chevrolet Silverado 3500 HD gives you two powerful engine choices. It comes standard with a robust 6.6L V8 Gas engine. If you need extra muscle, there's an optional DURAMAX 6.6L turbo-diesel V8 engine available. Both engines pair with an Allison 10-speed automatic transmission and an automatic locking rear differential for enhanced handling and performance. The diesel option delivers exceptional power for demanding work and towing tasks. Both configurations are engineered for durability and reliability.
