The 2025 Chevrolet Silverado 3500 HD comes standard with a powerful 6.6L V8 Gas engine. If you need extra muscle for demanding tasks, an optional DURAMAX 6.6L turbo-diesel V8 engine is available. Both engines are matched with an Allison 10-speed automatic transmission and include an automatic locking rear differential for enhanced handling.

The truck also features Digital Variable Steering Assist, which dynamically adjusts steering based on speed and road conditions for a more comfortable drive. Whether you choose gas or diesel power, you'll get the capability to handle serious work while enjoying a smooth, confident ride.
