What is the difference between the 3500, 4500, and 5500 Chassis Cab?
The three Chassis Cab models represent escalating tiers of payload and GVWR capacity. The 3500 is the entry point, suited for lighter upfit applications such as utility bodies and flatbeds. The 4500 steps up the GVWR for medium-duty builds like service bodies and crane trucks. The 5500 carries the highest payload in the lineup, up to 12,260 lbs gas payload and 34,540 lbs diesel towing, making it the right choice for the most demanding commercial builds including dump bodies, refuse trucks, and roll-offs.
What engine options are available on the 2026 RAM Chassis Cab?
The 2026 RAM Chassis Cab comes standard with the 6.4L HEMI V8 producing 375 horsepower and 429 lb-ft of torque, paired with the TorqueFlite 8 eight-speed automatic. The available 6.7L Cummins Turbo Diesel I6 delivers 360 horsepower and 800 lb-ft of torque, the preferred choice for maximum towing and PTO-intensive work, paired with the TorqueFlite HD eight-speed automatic. Both transmissions provide PTO access from both sides in 4x2 and 4x4 configurations.
What makes the RAM Chassis Cab upfit-friendly?
The 2026 RAM Chassis Cab is purpose-built for upfitting with straight flat frame rails, predrilled frame mounting holes, and standard cab-axle lengths across nine wheelbase options and two cab types. The relocatable Center High-Mounted Stop Lamp Camera allows you to reposition the rear camera view to suit your specific body installation. Six auxiliary switches, including a dedicated PTO switch when equipped, and the best-in-class available 2.4kW onboard power system give upfitters and operators the electrical infrastructure they need right out of the box.
How does the Power Take Off (PTO) work on the RAM Chassis Cab?
Both automatic transmissions on the 2026 RAM Chassis Cab provide PTO access from the left and right side in both 4x2 and 4x4 configurations, which is critical for a wide range of upfit applications. With the available 6.7L Cummins Diesel, Split-Shaft Mode offers two PTO speed options and can deliver minimum split-shaft horsepower even when the truck is stationary, making it ideal for hydraulic cranes, aerial lifts, and other PTO-powered equipment that must operate at rest.
What fuel tank options are available on the 2026 RAM Chassis Cab?
The 2026 RAM Chassis Cab offers multiple fuel tank configurations to match your operating range. The standard setup is a 52-gallon rear-mounted fuel tank. An available 22-gallon midship tank can be added, bringing total combined capacity to 74 gallons, the largest-in-class available dual fuel tank. For diesel operators running extended routes across Florida or the southeast, this dramatically reduces fuel stops and total operating cost over high-mileage service cycles.
