How much horsepower does a Chevy 3500 dually have?
The horsepower of a Chevy Silverado 3500HD with dual rear wheels depends on the engine you choose. The gasoline V8 option delivers about 401 horsepower, while the Duramax turbo-diesel option offers about 445 horsepower. The dual rear-wheel setup does not change these engine-based horsepower figures.
Engine options and horsepower
The Silverado 3500HD DRW is offered with two powertrain options. The list below shows the horsepower figures for the current generation through model year 2024.
- Gasoline 6.6-liter V8: 401 horsepower and 464 lb-ft of torque.
- 6.6-liter Duramax turbo-diesel V8: 445 horsepower and 910 lb-ft of torque.
These numbers reflect standard output for the two available engines. Torque, which heavily influences towing and payload performance, is significantly higher on the diesel option, while the gasoline engine provides solid everyday power for lighter hauling needs.
Does the dual rear-wheel layout affect horsepower?
The dual rear-wheel (DRW) configuration is primarily a payload and stability enhancement. It does not alter the engine’s horsepower rating; horsepower is governed by the chosen engine and transmission. DRW helps with higher towing capacities and heavier payloads, making the truck better suited for commercial or heavy-duty work.
Practical considerations for choosing engine power
Motorists weighing duty cycle and fuel economy should consider: the diesel’s higher torque for heavy towing and long-duration workloads, versus the gasoline engine’s adequate power for everyday driving and lighter towing. Factors such as towing capacity, payload requirements, fuel costs, and maintenance intervals should guide the final choice.
Summary
For the Chevy Silverado 3500HD DRW, horsepower depends on the engine: 401 hp with the 6.6L gas V8 and 445 hp with the 6.6L Duramax diesel. The dual rear-wheel setup enhances payload and stability but does not change the engine’s horsepower. Prospective buyers should align their selection with towing needs, payload requirements, and long-term operating costs.

What's the difference between a 2500HD and a 3500HD?
The main difference between a 2500HD and 3500HD is the 3500HD's higher towing and payload capacities, which are achieved through its beefier suspension and optional dual rear wheels. While the 2500HD is a heavy-duty truck suitable for most tasks, the 3500HD is built for maximum power and is ideal for the heaviest jobs like large trailers and commercial use. The 2500HD is often a better choice for a daily driver due to its narrower body and slightly smoother ride, while the 3500HD's dual-wheel option makes it wider and less maneuverable in urban areas.
This video explains the differences between 2500HD and 3500HD trucks: 58sSoCal ChevyYouTube · Oct 5, 2023
Towing and payload
- 3500HD: Has higher maximum towing and payload capacities, with some configurations allowing for up to 36,000 lbs of towing.
- 2500HD: Offers strong, but lower, towing and payload capacities, suitable for most heavy-duty tasks.
Drivetrain and chassis
- 3500HD: Can be configured with dual rear wheels (DRW) to increase stability and load capacity, though it's also available in single rear wheel (SRW). It has a more robust suspension and chassis to handle heavier loads.
- 2500HD: Is only available with single rear wheels (SRW), making it narrower and easier to handle in tight spaces.

Ride and maneuverability
- 3500HD: The dual rear wheel configuration can result in a stiffer, more robust ride, especially when unladen, and a larger turning radius.
- 2500HD: Typically provides a slightly softer ride quality compared to the 3500HD, making it a more comfortable option for everyday driving and parking.
Other similarities
- Engine and transmission: Both models often share the same engine and transmission options, like the 6.6L turbo diesel with 975 lb-ft of torque and a 10-speed automatic transmission.
- Interior and technology: Many interior features, technology, and cab configurations are identical between the two trucks.
