Ram Launches 2027 Chassis Cab With Upfitter Features
The 2027 Ram Chassis Cab line adds gasoline and diesel options, flexible cab-to-axle lengths, and a 270-degree surround-view camera on heavy-duty models.
Updated on Nov. 6, 2026 in Trucks
Ram has released the 2027 Ram Chassis Cab line, designed for upfitters with frame-level plumbing and electrical routing and no components above the rear frame rails. Ram also added a 270-degree surround-view camera system to its Ram 3500, 4500 and 5500 Chassis Cab models.
Why it matters
The redesigned chassis gives commercial vehicle builders a cleaner platform for installing equipment, which can shorten conversion work for fleet and work-truck customers. The added camera system adds visibility for maneuvering large vehicles.
The 6.7L Cummins I-6 produces 360 hp and 800 lb-ft, while the Ram 5500 Cummins is rated to tow up to 34,540 pounds and carries a 43,000-pound gross combined weight rating. The extraction does not indicate how these ratings differ from earlier model years.
The players
Ram
Ram is the truck and commercial vehicle brand of Stellantis, known for heavy-duty pickups and chassis cab models used by upfitters and fleet operators.
The details
The 2027 Ram Chassis Cab line is offered with gasoline and diesel powertrains and cab-to-axle lengths of 60, 84, 108 and 120 inches.

Roadmap
The 2027 Ram Chassis Cab line extends Ram's Cummins 6.7L Turbo Diesel I-6 heavy-duty lineup into a platform designed for upfitting. The move positions Ram's chassis cab offering against rival heavy-duty pickup and commercial chassis makers in the work-truck segment.
Upfitters and fleet buyers can plan conversions around cab-to-axle options of 60 to 120 inches and frame-level plumbing and wiring. Drivers of Ram 3500, 4500 and 5500 Chassis Cab models gain a 270-degree surround-view camera for maneuvering.
The takeaway
Fleet managers and upfitters evaluating heavy-duty chassis should compare the available cab-to-axle lengths and powertrain options against their intended body and equipment configurations before ordering.
