2027 Ram 2500 FAQ: Towing, Power Wagon Diesel, Specs & More
The 2027 Ram 2500 gains a first-ever Cummins diesel option in the Power Wagon, producing 1,075 lb-ft of torque. That is a bigger story than any single spec number: the most off-road-capable Ram now pairs with the segment's best diesel. This page answers the questions shoppers ask most, and links to inventory at Johnsons of Kingfisher.
Powertrain & Performance
What engines are available on the 2027 Ram 2500?
Two engines are offered. The base engine is the 6.4L HEMI V8, producing 405 hp and 429 lb-ft of torque. The available engine is the 6.7L Cummins High-Output Turbo Diesel I6, producing 430 hp and 1,075 lb-ft of torque. Both pair with an eight-speed automatic transmission.
What is the biggest powertrain news for 2027?
The biggest change is that the 6.7L Cummins HO Turbo Diesel is now available in the Ram 2500 Power Wagon for the first time in the model's history. Ram customers had requested this pairing for years, and 2027 is the year it arrives.
How much torque does the 2027 Ram 2500 Cummins diesel make?
1,075 lb-ft of torque, delivered at 1,800 rpm. That figure is best-in-class for base diesel torque in the heavy-duty segment. Ram Heavy Duty newsroom
What transmission does the 2027 Ram 2500 use?
The HEMI V8 uses a TorqueFlite HD 8HP75 eight-speed automatic. The Cummins diesel uses a TorqueFlite HD 8AP1075 eight-speed automatic, which is a heavier-duty unit tuned to handle the diesel's torque output.
What axle ratio does the Cummins diesel 2500 use?
The Cummins diesel pairs with a 3.42 rear axle ratio. This setup was introduced on the 2025 Ram Heavy Duty lineup and is optimized to deliver strong towing performance in lower gears while improving highway fuel efficiency and reducing NVH in gears seven and eight.
How does the new 3.42 axle ratio affect driving?
The 3.42 ratio provides a higher final drive in gears one through six for confident acceleration and towing, and a numerically lower ratio in gears seven and eight for quieter, more fuel-efficient highway cruising. It is standard on all diesel 2500 configurations.
Towing & Payload
How much can the 2027 Ram 2500 tow?
With the Cummins HO Turbo Diesel, the 2027 Ram 2500 tows up to 20,000 lbs when properly equipped. With the 6.4L HEMI V8, maximum towing reaches up to 17,740 lbs when properly equipped. Actual ratings vary by cab, bed, axle ratio, and configuration. 2027 Ram 2500 capability details
What is the payload capacity of the 2027 Ram 2500?
The best-in-class payload figure of 4,580 lbs is achieved with the HEMI V8 and the available Payload Upgrade Package. That package raises the GVWR from 10,000 lbs to 11,040 lbs and includes a 3500 frame, leaf springs, and an anti-spin rear differential. Diesel-equipped 2500s reach up to 3,990 lbs of payload.
What is the Payload Upgrade Package and which trims can get it?
The Payload Upgrade Package is available on most Ram 2500 trucks equipped with the 6.4L HEMI V8 in Regular or Crew Cab configurations. It includes a 3500 frame, leaf-spring rear suspension, upgraded rear shocks, and an anti-spin differential. It is available on Tradesman, Big Horn/Lone Star, Laramie, Limited, and Limited Longhorn trims.
Does the 2027 Ram 2500 Power Wagon diesel tow as much as a standard 2500 diesel?
No. The Power Wagon's towing capacity is lower than a non-Power Wagon diesel 2500 because of its off-road-specific suspension, axle, and tire setup. The Power Wagon diesel is rated for approximately 13,000 lbs of towing in crew cab configuration based on published spec charts. Buyers who need maximum towing capacity should look at non-Power Wagon diesel 2500 configurations, which reach 20,000 lbs.
Can the 2027 Ram 2500 Power Wagon diesel be set up for fifth-wheel or gooseneck towing?
Yes. The Power Wagon diesel adds fifth-wheel and gooseneck preparation for the first time in 2027. This is a significant expansion of the Power Wagon's utility, as it was not available on this model before. The prep package includes a factory-installed rear-axle structural crossmember with integrated mounting hardware.
What towing technology is available on the 2027 Ram 2500?
Available towing technology includes Trailer Reverse Steering Control, a Digital Rearview Mirror with tow mode, a 360-degree surround view camera, trailer reverse guidance, trailer tire pressure monitoring, and class-exclusive heated power convex trailer tow mirrors with power-folding, power-telescoping, and memory. The Tow Technology Group and Tow Technology Plus Group bundle these features.
