What’s New for 2027
The biggest news for 2027 is the debut of the Ram 2500 Power Wagon with the 6.7-liter Cummins High-Output turbo diesel. This is the first time the Cummins diesel has been available in the Power Wagon, producing 430 horsepower and a best-in-class base diesel torque of 1,075 lb.-ft. The Power Wagon with Cummins diesel arrives in the second half of 2026. It retains the Power Wagon’s title as the most off-road-capable full-size pickup, adding fifth-wheel/gooseneck preparation for the first time and a 31-gallon fuel tank sized for an estimated 600-mile range.
Ram 3500 4×4 SRW Regular Cab 8-foot box and Crew Cab 6-foot, 4-inch box trucks with the 6.4L HEMI V8 now offer a maximum GVWR of 11,440 lbs, an increase of 400 lbs over the 2026 model year. That directly increases payload capability for buyers in those configurations.
A new Payload Upgrade Package is available on most Ram 2500 trucks with the 6.4L HEMI V8, raising GVWR from 10,000 lbs to 11,040 lbs and delivering a best-in-class 2500 payload of 4,580 lbs. The package includes a 3500 frame, leaf springs, and anti-spin rear differential.
Heavy-duty trucks equipped with the 6.4L HEMI V8 receive a new Symbol of Protest V8 fender badge. Tradesman, Black Express, Warlock, Rebel, Power Wagon and trucks with the Night Edition Package receive a Satin Black version of that badge.
The Sport Appearance Package and Night Edition Package are now offered on trucks equipped with Level 1 and Level 2 equipment groups, previously limited to the Level 1 Plus and Level 2 Plus equipment groups. A sport performance hood is now available as a standalone option on Rebel and Power Wagon, as well as on Big Horn models equipped with the Night Edition or Sport Appearance package.
New colors for 2027 include Serrano Green Metallic and Tank Clear-Coat, both arriving at late availability.
Trim Lineup
The 2027 Ram 3500 Heavy Duty spans multiple trim levels, from work-focused to full-luxury. Every trim receives the core capability numbers listed below, and each step up adds comfort and technology rather than changing the fundamental powertrain options.
Tradesman
Tradesman is the entry point. It focuses on durability and capability without unnecessary extras, and it is the trim most commonly spec’d for fleet and commercial use.
Big Horn / Lone Star
Big Horn / Lone Star adds a more finished interior and convenience features suited to buyers who use the 3500 as both a work truck and a daily driver.
Laramie
Laramie brings leather seating and a noticeably more upscale cabin, including available bucket seats and a 40/20/40 split-folding front bench option.
Limited
Limited moves up from Laramie with a premium leather interior, additional technology content, and a higher level of standard comfort features throughout the cabin.
Limited Longhorn
Limited Longhorn sits at the top of the hierarchy. It pairs premium leather seating with genuine wood and aluminum interior accents in a western-influenced design, available in either black ebony red or all-black interior configurations. At this level the 3500 competes directly with luxury sedans on interior refinement while still towing 37,020 lbs.
The Mega Cab body style is available across several trims and adds Class-Exclusive reclining rear seats and Class-Exclusive forward fold-flat rear seats, making it the right choice for crews that spend long hours on the road between Boscobel and Prairie du Chien job sites.
Performance & Powertrain
Two engine paths are available on the 2027 Ram 3500.
Available High-Output 6.7L Cummins Turbo Diesel I6

|---|---|
| Torque | 1,075 lb.-ft. of torque at 1,800 RPM |
| Maximum Towing Capacity | 37,020 lbs when properly equipped |
| Maximum Diesel Payload | 6,460 lbs when properly equipped |
The Cummins engine features advanced airflow improvements, enhanced cold-start capability, a Smart Diesel Exhaust Brake for controlled descent with heavy loads, and a design built for simple serviceability. Heavy-duty four-wheel disc antilock brakes work alongside the available Automatic Smart Exhaust Brake to slow loaded trailers with confidence.
6.4L HEMI V8
The 6.4L HEMI V8 is paired with the TorqueFlite 8-speed automatic transmission.

Crew Cab models with an 8-foot bed offer a Best-in-Class available 50-gallon fuel tank, extending range between stops for buyers covering long distances across rural Wisconsin.
Interior, Comfort & Cargo
The 2027 Ram 3500 cabin balances job-site utility with genuine comfort. Front seating options include a 40/20/40 split-folding bench or available bucket seats. Rear seating offers three 60/40 split-folding configurations, and Mega Cab models add the Class-Exclusive reclining and forward fold-flat rear seats mentioned above.
Storage is a real strength. Class-Exclusive available in-floor Ram Bins in Crew Cab models create hidden, secure storage for tools and small equipment. The rear cubby bin gives rear passengers a place to stash items quickly, and a 115-volt outlet in the rear lets riders charge devices or run small tools.
The available 900-watt Harman Kardon premium audio system uses 17 speakers and Interior Active Noise Cancellation to deliver clarity that stands out in a truck cab, especially on long highway hauls between Richland Center and the job site.
Best-in-Class available onboard power reaches 2.4 kilowatts, turning the truck bed into a genuine jobsite power station. A 400-watt inverter handles basic needs, and the 2.4 kW option covers power tools and larger equipment.
Available power side running boards, an available Mopar bed step, and a dampened tailgate with available power release make entering and exiting the cab or bed easier after a full day of work.
Technology & Infotainment
The Uconnect 5 NAV system anchors the technology lineup. At its largest, the available touchscreen measures 14.5 inches, the largest in class, giving drivers a clear display for navigation, towing settings, and media.
The available 12-inch Digital Cluster Display puts full-color 3D graphics and navigation within the driver’s sightline. It also shows Trailer Tire Pressure Monitoring for up to four trailers, available with the Tow Tech Package, and dedicated Off-Road Pages with pitch, roll, and traction control readouts.
Uconnect 5 NAV supports up to five personalized driver profiles and tow-specific navigation. Wireless Apple CarPlay and wireless Android Auto are both available, with Android Auto now supercharged with Google Gemini integration. The available Class-Exclusive 10.25-inch front passenger interactive display and Class-Exclusive dual wireless charging pads, with ventilation to keep devices cool, round out the connectivity features.
Ram Connect One Services provide remote vehicle start via key fob or Ram Digital Key, vehicle finder, and Send & Go destination sending.
The available Digital Rearview Mirror uses an LCD monitor fed by the truck’s rear-facing camera. When paired with the Tow Technology Plus Group and exterior mirror cameras, it provides left and right views alongside the trailer. Class-Exclusive available Power Convex Trailer Tow Mirrors offer forward and reverse spotter functionality and power-adjustable telescopic extension.
The available Trailer Reverse Steering Control lets drivers use a dedicated knob to guide the trailer while the system manages the steering wheel, removing one of the most frustrating aspects of backing a large trailer.
Safety & Driver Assistance
The 2027 Ram 3500 carries over 100 standard and available safety and security features. Notable items include:
Class-Exclusive Standard Adaptive Cruise Control
Class-Exclusive Standard Adaptive Cruise Control comes standard, not optional. It maintains a driver-set following distance and can slow the truck to 0 mph automatically, even with a trailer attached.
Forward Collision Warning with Active Braking
Forward Collision Warning with Active Braking can apply full brakes to bring the truck to a complete stop, including when towing.
Available LaneSense Lane Departure Warning with Lane Keep Assist
Available LaneSense Lane Departure Warning with Lane Keep Assist uses enhanced lane-keeping logic to steer the truck back into its lane when an unintentional drift is detected.
Available Drowsy Driver Detection
Available Drowsy Driver Detection monitors driver behavior and issues an audible and visual alert when rest is recommended.
Available Traffic Sign Recognition
Available Traffic Sign Recognition displays detected road sign information on the Digital Cluster Display or Head-Up Display.
Available 360-Degree Surround View Camera
Available 360-degree Surround View Camera gives a complete overhead view of the truck and its surroundings, useful when maneuvering in tight spaces with large attachments.
The LED Trailer Hitch Light, built into the tailgate handle area, illuminates the hitch connection point to simplify hookups at night. The Rear Seat Reminder Alert prompts the driver to check rear seats before exiting.
Who It’s For / vs. the Prior Year
The 2027 Ram 3500 is built for buyers who need industrial-strength numbers without giving up daily comfort. The 37,020-lb diesel tow rating and 7,580-lb gas payload are the core arguments for this truck over a lighter-duty pickup.
The new Symbol of Protest V8 fender badge gives gas-powered buyers visual recognition of their powertrain choice on the exterior. The Power Wagon Cummins diesel debut and the GVWR increase for 3500 4×4 SRW configurations make this a more capable model year across the board compared to 2026.
Buyers upgrading from a 2026 Ram 3500 will find capability numbers holding steady at the top of the class in most configurations, with the 4×4 SRW GVWR increase delivering a concrete payload advantage in select builds. The 2027 model year focuses on powertrain identity, off-road expansion via the Power Wagon diesel, and continued refinement of the technology and safety suite rather than a complete overhaul.
If you need a truck that tows more than 30,000 lbs, hauls heavy payloads through a Wisconsin winter, and still delivers a premium cabin experience, the 2027 Ram 3500 is the specific configuration to evaluate. Ram 3500 official capability disclosures
