Key Features of the 2027 RAM 3500 Chassis Cab
6.7L Cummins® Turbo Diesel I6 Engine
The available 6.7L Cummins® Turbo Diesel I6 engine is one of the most important reasons business owners consider the 2027 Ram 3500 Chassis Cab. Cummins diesel powertrains are known across commercial applications for durability and confident performance, and Ram pairs this engine with thoughtful supporting technology. OEM content notes that the diesel engine is designed with advanced air flow for performance improvements, enhanced cold-start capability, a Smart Diesel Exhaust Brake, robust components and simple serviceability. Across the 2027 Ram Chassis Cab lineup, the available diesel configuration supports demanding trailering and a maximum GCWR of up to 43,000 pounds on properly equipped 5500 models. For 3500 shoppers, the key benefit is the character of the engine: strong low-speed pulling confidence, long-haul composure and compatibility with work-focused systems such as available PTO configurations. When matched with the available TorqueFlite® HD 8-Speed Automatic Transmission, this powertrain is designed to deliver smooth shifting, durability and optimized performance in a commercial environment.
6.4L HEMI® V8 Engine
The standard 6.4L HEMI® V8 engine gives the 2027 Ram 3500 Chassis Cab proven gas-powered capability for businesses that prioritize responsive performance, simpler fueling needs and strong everyday versatility. Ram notes that this engine is built for work with robust components and is known for low-end torque, which is valuable when moving equipment, hauling materials or operating in stop-and-go jobsite traffic. OEM content lists a cast-iron block, aluminum cylinder head, Multiple Displacement System and a dual alternator option among its notable engineering details. The 6.4L HEMI® V8 engine produces up to 375 horsepower and 429 lb-ft of torque in the Chassis Cab lineup, with best-in-class gas horsepower on 4500 and 5500 models. Paired with the TorqueFlite® 8-Speed Automatic Transmission, it is designed to keep power delivery smooth and responsive. For many local businesses, this gas powertrain may be the practical choice for utility bodies, service routes, municipal use and mixed driving needs.
Upfit-Ready Frame
A chassis cab purchase starts with one major question: will this truck support the body and equipment your work requires? The 2027 Ram 3500 Chassis Cab is built to answer that question with an upfit-friendly structure. Ram highlights straight flat frame rails, standard frame cab axle lengths and predrilled frame mounting holes, all designed to make upfitting more efficient. The 2027 Ram Chassis Cab lineup can be configured with two cab types, four cab axle lengths and nine wheelbases, giving buyers a wide range of possibilities for specialized bodies and equipment. The steel rear frame strength of 50,000 psi adds the kind of foundation expected from a commercial truck. For a business that needs tool compartments, lift gates, flatbeds, storage bodies, cranes or other professional upfits, this flexible platform matters. The Advanced Vehicle System Interface Module adds another important layer by offering convenient access to more than 70 vehicle inputs and outputs, including lighting and Power Take Off controls.
Enhanced Power Take Off Configurations
Power Take Off capability can be a deciding factor for commercial buyers because many upfits depend on vehicle-driven power. The 2027 Ram Chassis Cab lineup offers enhanced PTO configurations designed around flexibility. Ram states that both TorqueFlite HD automatic transmissions offer PTO availability from the left and right side with 4x4 or 4x2 configurations. With the available 6.7L Cummins® Turbo Diesel I6 engine, operators can choose between two speeds with Split-Shaft Mode, and minimum split-shaft horsepower is provided even when stationary. That kind of capability can be valuable for applications such as utility service, towing operations, dump bodies, hydraulic equipment and specialty vocational builds. The integrated switch bank includes six auxiliary buttons, and on models equipped with available PTO, the sixth auxiliary switch becomes a dedicated PTO switch. For buyers who need a truck to run more than transportation duties, this Ram provides the control points and engineering support to integrate vehicle power into the upfit.
Uconnect® 5 NAV Infotainment System
The 2027 Ram 3500 Chassis Cab is highly capable, but it also recognizes that modern work trucks are mobile offices. The Largest-in-Class Standard Touchscreen Infotainment System is an 8.4-inch display with Uconnect® 5 NAV capability. According to OEM content, the system lets drivers create up to five driver profiles, view tow-specific navigation, explore Off-Road Pages and access available Ram Connect One services for safety and security features, comfort and control, personalized benefits and more. The available 12-inch Digital Cluster Display adds full-color 3D graphics, color customization, safety and security alerts, navigation, gauge summaries, vehicle diagnostics and Trailer Tow Pages. Trailer Light Check and Trailer Brake Status can be viewed through this display, helping drivers verify important trailer information before heading out. Available Ram app functionality powered by Ram Connect can support features such as Send & Go, Vehicle Finder, Remote Vehicle Start and remote lock or unlock when properly equipped. For a work truck, that is useful technology, not decoration.
