The 2025 Chevrolet Silverado 3500 HD offers two powerful engine choices to match your needs.

It comes standard with a 6.6L V8 Gas engine that delivers strong performance for everyday and demanding tasks. If you need extra power, an optional DURAMAX 6.6L turbo-diesel V8 engine is available, giving you maximum muscle and efficiency.

Both engines pair with an Allison 10-speed automatic transmission and include an automatic locking rear differential for confident handling in any condition. The truck also features Digital Variable Steering Assist, which dynamically adjusts steering based on speed and road conditions for a smoother, more comfortable drive.
