Chevrolet Silverado 3500HD Chassis Cab Review

The Chevrolet Silverado 3500HD Chassis Cab is a heavy-duty work truck designed for commercial upfitting. It’s not a complete vehicle as it leaves the factory, but rather a platform for building specialized trucks like tow trucks, boom trucks, or utility vehicles. This review will cover its core features and specifications, focusing on what makes it a strong choice for businesses needing a robust chassis.

Key Features & Specifications:

Engines: The Silverado 3500HD Chassis Cab offers two powerful engine options:
- 6.6L V8 Gas Engine: Produces 470 horsepower and 470 lb-ft of torque. A solid choice for applications where gasoline is preferred or where emissions regulations are less stringent.
- 6.6L Duramax Turbo-Diesel V8 Engine: The flagship engine, delivering 470 horsepower and a massive 975 lb-ft of torque. This is the go-to choice for heavy towing and demanding applications. It’s paired with a 10-speed Allison automatic transmission.
Transmission: As mentioned, the Duramax diesel is exclusively paired with the Allison 10-speed automatic. The gas engine is paired with a 10-speed automatic as well. Both transmissions are known for their durability and smooth shifting.

Chassis & GVWR: The chassis cab is available in various wheelbases and GVWR (Gross Vehicle Weight Rating) configurations, ranging up to 14,500 lbs. This flexibility allows businesses to tailor the truck to their specific needs. Different axle ratios are also available.
Towing Capacity: Maximum towing capacity varies significantly based on configuration, but can exceed 20,000 lbs when properly equipped with the Duramax diesel and dual rear wheels. Payload capacity is also substantial, exceeding 7,000 lbs in some configurations.
Upfitting Options: This is where the chassis cab truly shines. Chevrolet provides a clean, robust platform for body builders to install specialized equipment. The chassis is designed to accommodate a wide range of bodies and accessories. There are numerous body builder resources available from Chevrolet.

Technology & Safety: While focused on work, the Silverado 3500HD Chassis Cab isn’t lacking in technology. Features include:
- Chevrolet Infotainment 3 System: Available with a 7 or 8-inch touchscreen, Apple CarPlay and Android Auto compatibility.
- Advanced Trailering System: Provides helpful tools for towing, including trailer light testing and incline grade braking.
- Safety Assist Technologies: Includes features like Automatic Emergency Braking, Forward Collision Alert, and Lane Departure Warning.
- HD Rear Vision Camera: Offers a clear view of what’s behind the truck.
Interior: The interior is functional and durable, designed to withstand the rigors of commercial use. Trim levels range from Work Truck (WT) to LT, offering increasing levels of comfort and convenience. Available features include vinyl or cloth seating, power windows and locks, and air conditioning.

Pros:

Exceptional Power & Towing: The Duramax diesel engine provides class-leading power and towing capacity.
Highly Customizable: The chassis cab design allows for a wide range of upfitting options.
Durable & Reliable: Chevrolet has a long history of building tough and reliable trucks.
Advanced Technology: Offers a good balance of work-focused features and modern technology.
Strong Resale Value: Heavy-duty trucks generally hold their value well.

Cons:

Ride Quality: As a heavy-duty work truck, the ride can be firm, especially when unladen.
Fuel Economy: Fuel economy is not a priority for this type of vehicle, and it will be lower than lighter-duty trucks.
Price: Heavy-duty trucks are expensive, and the cost can increase significantly with optional equipment and upfitting.
Maneuverability: The large size and long wheelbase can make maneuvering in tight spaces challenging.

Overall:

The Chevrolet Silverado 3500HD Chassis Cab is a compelling choice for businesses that need a robust and highly customizable platform for building specialized work trucks. Its powerful engines, durable construction, and advanced technology make it a valuable asset for a wide range of applications. While it may not be the most comfortable or fuel-efficient vehicle, it excels at what it’s designed to do: provide a solid foundation for getting the job done. Careful consideration of the specific application and upfitting requirements is crucial when selecting the appropriate configuration.
