The 2027 Ram 2500 Power Wagon will be available for the first time with the 6.7-liter Cummins High-Output (HO) turbo-diesel inline-six, and a new Ram 2500 Emergency Response Vehicle (ERV) enters the heavy-duty lineup as Ram’s first pursuit-capable three-quarter-ton truck offered to fleet customers.
The Cummins HO is backed by a TorqueFlite HD eight-speed automatic transmission and puts out 430 horsepower and 1,075 lb.-ft. of torque. Preliminary ratings for the 2500 with that engine stand at up to 20,000 lbs. maximum towing and up to 3,990 lbs. maximum payload. The 6.4-liter HEMI V8, producing 405 horsepower and 429 lb.-ft. of torque through a TorqueFlite 8HP75-LCV eight-speed automatic, carries preliminary ratings of up to 17,740 lbs. maximum towing and up to 4,580 lbs. maximum payload.
Preliminary 3500 figures follow a similar pattern. The Ram 3500 with the HEMI V8 is rated for up to 18,140 lbs. maximum towing and up to 7,580 lbs. maximum payload, while the 3500 with the Cummins HO turbo diesel reaches up to 37,020 lbs. maximum towing and up to 6,460 lbs. maximum payload.
A new Payload Upgrade Package for most Ram 2500 trucks equipped with the 6.4-liter HEMI V8 pushes the GVWR from 10,000 lbs. to 11,040 lbs., yielding a best-in-class 2500 payload of 4,580 lbs. Priced at $835 MSRP, the package bundles a 3500 frame, leaf-springs and an anti-spin rear differential, and is available on the Tradesman, Big Horn/Lone Star, Laramie, Limited and Limited Longhorn trims.
The Ram 3500 4×4 single-rear-wheel (SRW) Regular Cab with an 8-foot box and Crew Cab with a 6-foot, 4-inch box, both powered by the 6.4-liter HEMI V8, gain a maximum GVWR of 11,440 lbs. for 2027, up 400 lbs. in both GVWR and payload capability from the 2026 model year.
On the Power Wagon, the 6.4-liter HEMI V8 variant reintroduces an optional beadlock-capable wheel. A Warn electric winch is now offered as a standalone option on Rebel and Power Wagon models with the 6.4-liter HEMI V8, dropping the previous requirement for the Level 1 Equipment Group. A sport performance hood moves to a standalone option on Rebel and Power Wagon as well, and extends to Big Horn models fitted with the Night Edition or Sport Appearance package.
The Sport Appearance Package and Night Edition Package expand to trucks equipped with Level 1 and Level 2 equipment groups, having previously been confined to the Level 1 Plus and Level 2 Plus equipment groups. An anti-spin rear differential becomes a standalone option on the 2500 Tradesman, where it had required the Level 1 Equipment Group. Laramie models pick up expanded RamBox availability and new optional body-color fender flares.
Every heavy-duty truck equipped with the 6.4-liter HEMI V8 gets a new Symbol of Protest V8 fender badge, with Tradesman, Black Express, Warlock, Rebel, Power Wagon and Night Edition Package trucks receiving a Satin Black version. Two new exterior colors join the palette: Serrano Green Metallic and Tank Clear-Coat, each with late availability.
Towing technology across the lineup includes an available fully digital rearview mirror with tow mode, trailer reverse steering control, Blind-spot Monitoring with Trailer Tow Detection System, class-exclusive heated power convex trailer tow mirrors with power-folding, power-telescoping and memory functionality, and Trailer-Tow Pages for comprehensive trailer monitoring. The 2500 offers two segment-exclusive rear suspension choices: a five-link coil system and an available automatic-leveling rear air suspension. The Ram 3500 retains the rear Hotchkiss leaf spring system and pairs it with an available supplemental air suspension system.
