Following last year's update of the light duty Ram 1500, the heavy duty Ram trucks get a refresh for 2025 with a redesigned Cummins 6.7L diesel and more tech

Powering the most basic Ram 2500 and 3500 pickups is still the 6.4-liter gasoline-burning Hemi V8, which drops 5 hp, now delivering 405 hp and 429 lb-ft of torque, pushed through an eight-speed ZF HD 8HP75 transmission.

Ram's heavy-duty trucks receive a comprehensive refresh that includes new exterior styling and interior upgrades.

Ram has finally revealed its 2025 HD and Chassis Cab lineups, incorporating many of the flashy upgrades that have already hit the standard Ram 1500 pickup. But there’s more to this overhaul than a fancier cabin and a new grille.
