RAM 3500 Chassis Cab Shopping FAQs

What are the primary engine and transmission combinations for the RAM 3500 Chassis?

The RAM 3500 Chassis features two primary commercial-grade powertrains. The standard engine is the 6.4L HEMI V8 producing 410 horsepower and 429 lb-ft of torque, mated to an efficient 8-speed automatic transmission. For heavy-duty industrial trailering, the available 6.7L Cummins Turbo Diesel delivers 360 horsepower and a massive 800 lb-ft of low-end torque, exclusively paired with the commercial AISIN 6-speed automatic transmission built for high-stress thermal management and PTO capability.

What does "Cab-to-Axle" length mean and why is it critical for upfitting?

Cab-to-Axle (CA) is the physical measurement from the back of the passenger cab to the centerline of the rear axle. This measurement is critical because commercial work bodies (such as standard 9-foot or 11-foot service beds, flatbeds, and dump bodies) are engineered to fit specific CA dimensions to guarantee proper rear weight distribution, structural clearance, and center-of-gravity parameters across the frame rails.

Can I roll my commercial upfitting and vocational bed costs into my auto loan?

Yes. To streamline your enterprise accounting and capitalization structures, Dave Smith Motors allows you to finance the complete commercial configuration. The cost of your RAM 3500 Chassis Cab, along with the installed service body, flatbed, hydraulic lifts, or commercial accessories, can be bundled together into a single commercial auto loan with a single monthly payment through our network of over 50 institutional lenders.
