How wide is a Chevy Silverado 3500 dually?
In short, the Silverado 3500HD dual rear-wheel version is about 80 inches wide without mirrors and roughly 96–100 inches wide with mirrors; exact width varies by model year, cab/bed configuration and wheel/tire package.
For readers planning parking, garage clearance, or highway routing, width is a practical concern that can shift with year, trim, and equipment. This article outlines typical figures and the factors that can change them, with guidance on how to verify the exact measurement for a specific vehicle.
Width benchmarks for common configurations
These figures reflect typical published values for recent Silverado 3500HD models and can vary slightly by cab style, bed length, and wheel/tire package.
- Width excluding mirrors (body width): about 80.0 inches (2032 mm).
- Width including mirrors (typical): roughly 96–97 inches (2438–2466 mm).
- Dual rear wheels (DRW) vs single rear wheel (SRW): DRW versions are usually at the upper end of the width range due to the extra tires, often around 98–100 inches with mirrors, depending on wheel and tire package.
These figures provide a practical baseline for planning and parking. For the exact value on a specific truck, consult the model-year spec sheet or the window sticker for that configuration.
How to verify the exact width for your truck
Because width can shift with year, trim and options, check the official spec sheet for the exact model year and configuration of your Silverado 3500HD. If you own the vehicle, the window sticker or the dealer build sheet will list the precise overall width including mirrors and the body width excluding mirrors. When in doubt, measure directly on the vehicle with the doors closed and the mirrors in their usual driving position.
Notes by model year and configuration
The core body width of the Silverado 3500HD remains around 80 inches across recent generations. Mirrored width can push the overall dimension into the mid-to-high 90s, and DRW variants tend to sit at the upper end of the range due to the dual rear tires. Exact figures vary by cab type (Regular, Double, Crew), bed length, and any wide fender flares or aftermarket wheels. Always rely on the official model-year documentation for precision.
Summary
Across widely sold configurations, the Silverado 3500HD dually is approximately 80 inches wide without mirrors and roughly 96–100 inches wide with mirrors. The dual-rear-wheel setup commonly places DRW models toward the upper end of that range. For exact numbers, consult the model-year spec sheet or window sticker for your specific truck.
