RAM Heavy Duty Capabilities

The 2025 RAM 2500 tops out at 20,000 lbs of towing capacity and up to 4,420 lbs of payload when properly equipped, with ratings varying by engine, axle ratio, and cab configuration. The RAM 3500 pushes those numbers further, reaching up to 36,610 lbs of max towing and 7,590 lbs of payload when properly equipped.

Heavy duty trucks come standard with electronic stability control and brake assist, and an available integrated brake controller supports trailer braking for loads operating near those limits.
