The 2025 Chevrolet Silverado 3500 HD offers two powerful engine choices. It comes standard with a 6.6L V8 Gas engine, and if you need extra power, there's an optional DURAMAX 6.6L turbo-diesel V8 engine. Both engines pair with an Allison 10-speed automatic transmission and include an automatic locking rear differential for superior handling. The diesel option is especially popular for maximum torque and efficiency on heavy-duty jobs. Both engines deliver the muscle you need for demanding tasks.
