Engine Options, Towing Capacity, Payload, and Fuel Efficiency for the 2026 Ram 5500 Chassis Cab

The 2026 Ram 5500 Chassis Cab delivers serious capability for businesses and professionals across Victorville, CA, and the surrounding High Desert communities of Hesperia, Apple Valley, Adelanto, Phelan, and Lucerne Valley. Built for demanding commercial applications, the 5500 pairs two proven powertrains with a new TorqueFlite® HD eight-speed automatic transmission for 2026 — a significant upgrade that improves power delivery and operational efficiency across every configuration.

Available in Tradesman and Big Horn trims with Regular Cab and Crew Cab configurations, the Ram 5500 is engineered to support flatbed hauling, dump work, utility service, and virtually any upfit a commercial operation requires.

2026 Ram 5500 Engine Options at a Glance

The 2026 Ram 5500 Chassis Cab offers two powertrains — each paired with a new eight-speed automatic transmission for improved performance and efficiency.

6.7-Liter Cummins® Turbo Diesel I6 Engine

The available 6.7-liter Cummins® Turbo Diesel I6 engine remains the workhorse choice for heavy commercial duty. This turbocharged inline-six produces 360 horsepower and a commanding 800 pound-feet of torque, delivering the sustained low-end pulling power that construction, agriculture, and long-haul towing operations demand.

For 2026, the Cummins diesel is paired with the new TorqueFlite® HD eight-speed automatic transmission, manufactured by ZF Powerline. This eight-speed replaces the previous six-speed unit and provides improved acceleration, smoother power delivery, and enhanced efficiency under load — a meaningful upgrade for operators who depend on consistent performance across extended work cycles. The diesel powertrain also offers a Split-Shaft PTO mode, allowing operators to choose between two speeds even when the vehicle is stationary — a valuable feature for running hydraulic equipment and other PTO-driven accessories on the job site.

6.4-Liter HEMI® V8 Engine

The standard 6.4-liter HEMI® V8 engine provides a gasoline-powered alternative that delivers 375 horsepower and 429 pound-feet of torque. This naturally aspirated V8 is PTO-capable and features variable camshaft timing technology that helps balance performance with operational efficiency.

Paired with the TorqueFlite® 8 eight-speed automatic transmission, the HEMI V8 offers responsive throttle delivery and lower upfront acquisition costs compared to the diesel option. For fleet operators and businesses running lighter-duty commercial tasks or making frequent stops within the Victorville and Apple Valley areas, the gas engine provides a practical balance of capability and cost.

Choosing Between Diesel and Gasoline

The decision between these two powertrains comes down to operational priorities. The Cummins diesel excels in sustained heavy-duty applications — hauling heavy equipment, towing large trailers, and maintaining consistent power output over long distances and demanding terrain. Its 800 pound-feet of torque gives it a clear advantage in applications where load weight is the defining variable.

The HEMI V8 is well-suited for lighter commercial applications or mixed-use operations where quick throttle response and lower fuel costs at the pump offer day-to-day advantages. Both engines benefit from the upgraded eight-speed transmission platform for 2026, ensuring smooth, reliable power delivery regardless of which powertrain best fits the job.

Towing and Payload Capacity

The 2026 Ram 5500 Chassis Cab is built to handle some of the most demanding towing and payload requirements in the Class 5 commercial segment. Configuration choices — including cab style, wheelbase, axle ratio, and drivetrain — directly affect both towing and payload ratings, so working with the Victorville Motors team to match the right build to your specific application is an important step.

Towing and Payload by Engine

*When properly equipped. Actual ratings vary by configuration. Contact Victorville Motors for details.

Towing Technology

Advanced towing features include an integrated trailer brake controller and available fifth-wheel/gooseneck hitch prep packages, enhancing control and safety during towing operations across the High Desert’s varied terrain.

Payload Versatility

The 5500 supports substantial equipment and materials in its upfitted body. Dual rear wheels come standard, providing the stability needed for heavy payloads on job sites from Phelan to Lucerne Valley.

Fuel Efficiency Considerations

As a Class 5 commercial vehicle with a Gross Vehicle Weight Rating well above 8,500 pounds, the Ram 5500 Chassis Cab is not EPA-rated for fuel economy. Official miles-per-gallon figures are not published for this vehicle class, and actual fuel consumption varies significantly based on payload weight, terrain, driving conditions, and whether the vehicle is towing.

In general terms, diesel engines offer better fuel efficiency than gasoline engines under heavy load due to diesel fuel’s higher energy density and the Cummins engine’s torque-forward power delivery. For operations across the High Desert — where extended highway stretches and variable terrain are common — the diesel powertrain typically provides a fuel efficiency advantage for sustained heavy-duty use. The HEMI V8’s fuel consumption increases more notably under heavy towing loads, but may offer comparable efficiency for lighter-duty commercial tasks.

Operators should factor fuel costs into their total cost of ownership analysis when selecting between the two powertrains.

Technology and Safety

The 2026 Ram 5500 Chassis Cab pairs its commercial capability with a modern technology and safety suite designed to support driver awareness and productivity across long shifts.

Cabin Technology

Available high-definition 12-inch Uconnect® touchscreen powered by the Uconnect 5 system provides navigation, communications, and vehicle information in a clear, glove-friendly interface. An available 12-inch Digital Cluster Display with full-color 3D graphics keeps critical stats front and center. A standard electronic column shifter frees up console space, while Apple CarPlay®, Android Auto™, available dual wireless charging pads, and a 4G Wi-Fi® hotspot keep crews connected throughout the workday.

Safety Features

Standard safety includes Forward Collision Warning with Active Braking and Class-Exclusive Adaptive Cruise Control with Stop — which helps maintain a set following distance and can automatically adjust speed down to 0 mph, even with a trailer attached. Available safety features include Adaptive Forward Lighting, Drowsy Driver Detection, LaneSense® Lane Departure Warning with Lane Keep Assist, and Class-Exclusive Front and Rear Park Assist.

Built for the Job

The Ram 5500 Chassis Cab’s upfit-ready design supports a wide range of commercial applications. A 50,000 psi steel rear frame provides a strong foundation, while Class-Exclusive Active Air® Grille Shutters adapt to engine speed and load for optimized operating temperature. Available features like the Heavy Duty Snow Plow Prep Group and Electronic Front Axle Disconnect add operational flexibility for 4×4-equipped models.

Whether outfitting for flatbed hauling, dump work, or utility service in the Victorville area, the 2026 Ram 5500’s powertrain options and chassis design integrate seamlessly with specialized equipment. The truck also comes backed by a 10-Year/100,000-Mile Limited Powertrain Warranty — providing long-term confidence for businesses investing in their fleet.
