The 2025 Chevrolet Silverado 3500 HD comes with a powerful 6.6L V8 Gas engine as standard, and if you need extra muscle, an optional DURAMAX(R) 6.6L turbo-diesel V8 is available. Both engines are matched with an Allison(R) 10-speed automatic transmission and include an automatic locking rear differential for superior handling. Whether you choose gas or diesel, you'll get the performance and reliability built into Chevrolet's heavy-duty lineup. Current financing offers are available-ask Markquart Motors about special rates for Chevy owners and lessees.
