2027 Ram 2500: What's New, Trims, Specs & Cummins Diesel Power
The 2027 Ram 2500 Power Wagon gains the 6.7L Cummins HO Turbo Diesel for the first time, producing 1,075 lb-ft of torque. That torque figure is best-in-class for a base diesel and pairs with up to 20,000 lbs of towing in diesel-equipped trucks. This page covers every major change, trim, and spec, with current inventory available at Johnsons of Kingfisher.
What's New for 2027
The headline change for 2027 is Ram finally answering years of customer requests: the Power Wagon now accepts the 6.7L Cummins High-Output Turbo Diesel. That engine delivers 430 hp and 1,075 lb-ft of torque through a TorqueFlite HD 8-speed automatic paired with a 3.42 rear axle ratio. The combination unlocks up to 20,000 lbs of towing capacity, a number that was previously impossible in the Power Wagon.
Beyond the Power Wagon diesel, the 2027 model year brings several additional updates across the 2500 lineup:
- The Payload Upgrade Package is new for 2027 on most Ram 2500 trucks with the 6.4L HEMI V8. It raises GVWR from 10,000 lbs to 11,040 lbs and achieves a best-in-class 2500 payload of 4,580 lbs by incorporating a 3500 frame, leaf springs, and an anti-spin rear differential.
- Power Wagon diesel gains fifth-wheel/gooseneck preparation for the first time, expanding utility for commercial and recreational towing.
- A new Symbol of Protest V8 fender badge arrives on HEMI-equipped trucks, with Satin Black versions on Tradesman, Black Express, Warlock, Rebel, and Power Wagon.
- The Sport Appearance Package and Night Edition Package are now available on trucks equipped with Level 1 and Level 2 equipment groups, previously limited to the Level 1 Plus and Level 2 Plus groups.
- A sport performance hood is now available as a standalone option on Rebel and Power Wagon, and on Big Horn models with the Night Edition or Sport Appearance package.
- A Warn electric winch is now a standalone option on Rebel and Power Wagon with the 6.4L HEMI V8, no longer requiring the Level 1 Equipment Group.
- The Power Wagon diesel features a 31-gallon fuel tank delivering an estimated 600 miles of range, making it a strong choice for overlanders operating far from fuel stops.
- New exterior colors include Serrano Green Metallic and Tank Clear-Coat (both late availability).

Who It's For / vs. the Prior Year
Buyers who wanted the Power Wagon name with diesel torque had no path forward before 2027. This model year closes that gap completely. The 6.7L Cummins HO gives Power Wagon buyers 1,075 lb-ft of torque, estimated 600-mile range, and up to 20,000 lbs of towing, without giving up the off-road hardware that defines the model.
For buyers who work primarily with gas power, the new Payload Upgrade Package is the most meaningful 2027 addition. It converts a 2500 into a truck with 4,580 lbs of payload capacity using a 3500 frame and leaf springs, reaching a number no competitor in the 250/2500 class matches.
If you are in Kingfisher or anywhere nearby in central Oklahoma and are deciding between the 2026 and 2027 Ram 2500, the Power Wagon Cummins diesel and the HEMI Payload Upgrade Package are both changes significant enough to justify waiting for the 2027 model year.
