GM Chassis Cab Shopping FAQs

What are the primary engine and transmission options for new GM Chassis Cabs?

New GM Chassis Cabs feature two high-output commercial powertrains. The standard engine is the 6.6L Gas V8 producing 401 horsepower and 464 lb-ft of torque. For heavy-duty operations requiring maximum sustained low-end torque, the available 6.6L Duramax Turbo-Diesel delivers up to 470 horsepower and 975 lb-ft of torque. Both engines are paired with the legendary Allison 10-speed automatic transmission, built specifically for commercial load management and severe-duty towing stability.

What does "Cab-to-Axle" dimension mean and why does it matter for a fleet setup?

Cab-to-Axle (CA) is the exact physical measurement from the rear back wall of the passenger cab to the centerline of the rear axle. This dimensional standard is critical because all commercial upfit bodies-such as standard 9-foot service boxes, 12-foot flatbeds, or hydraulic dump beds-are built to align with specific CA lengths. Proper alignment ensures optimal vehicle weight distribution, axle load balance, and structural frame clearance.

Can commercial fleet buyers bundle upfitting costs into their primary auto loan?

Yes. To streamline your corporate accounting, equipment depreciation, and business capital structures, Dave Smith Motors allows you to finance the complete commercial setup. The cost of your new Chevy or GMC Chassis Cab, combined with the installed flatbed, service body, or heavy equipment tools, can be bundled together into a single commercial auto loan layout through our direct network of over 50 institutional lenders.
