You get excellent power choices with the 2025 Chevrolet Silverado 3500 HD. It comes standard with a powerful 6.6L V8 Gas engine, and if you need extra capability, an optional turbocharged DURAMAX 6.6L turbo-diesel V8 engine is available. Both engines are paired with an Allison 10-speed automatic transmission and feature an automatic locking rear differential to give you confidence in any driving condition. The truck also includes Digital Variable Steering Assist, which dynamically adjusts steering based on speed and road conditions for a smooth, comfortable ride. Whether you choose gas or diesel, you'll experience the durability and sophistication the Chevrolet brand is known for.
