The standard 6.4L HEMI V8 gives the 2027 Ram 3500 405 horsepower and 429 lb-ft through a TorqueFlite eight-speed. It is the payload leader, supporting the full 7,580-pound maximum, and it tows up to 18,140 pounds when properly equipped.

For flatbed work, service bodies, and bales in the bed, the HEMI carries more, costs less up front, and skips diesel aftertreatment entirely. The new V8 fender badge marks it for 2027.

• 405 horsepower and 429 lb-ft of torque
• Supports the maximum 7,580-pound payload
• Up to 18,140 pounds of towing when properly equipped
• TorqueFlite eight-speed automatic
• New V8 fender badge for 2027

The available 6.7L Cummins High Output is why a 2027 Ram 3500 can leave the scale house with 37,020 pounds behind it. Its 430 horsepower and best-in-class 1,075 lb-ft work through the TorqueFlite HD eight-speed, delivering grade-flattening pull at the low revs where trailers live.

Decades of Cummins durability are part of the buy, and around here that reputation is currency at resale time too. If the trailer is heavy today or getting heavier next year, this is the engine to order.

• 430 horsepower and 1,075 lb-ft of torque
• Best-in-class standard diesel torque
• Enables the 37,020-pound maximum tow rating
• TorqueFlite HD eight-speed automatic
• Proven Cummins heavy-duty durability

Run the HEMI if the bed does the work: it hauls the most payload, costs less to buy, and handles trailers to 18,140 pounds. Run the Cummins if the hitch does the work: everything past that number, and every long-haul mile, belongs to the diesel.

Either way you choose 4x2 or 4x4 and single or dual rear wheels, and every trim from Tradesman to Limited takes both engines. The team behind our 2027 Ram 3500 full review will quote your build both ways.

• HEMI: payload-first, value-first builds
• Cummins: maximum towing and long-distance work
• Both offer SRW or DRW configurations
• 4x2 and 4x4 with either engine
• Both engines span the full trim range
