Towing Capacity: Serious Muscle for Serious Jobs

If towing is at the top of your list, RAM Heavy Duty trucks set the bar. Depending on the configuration, the 2026 RAM 3500 offers up to 37,000 pounds of towing capacity with the High-Output Cummins® engine. That’s enough for massive trailers, RVs, horse haulers, or commercial equipment.

The 2026 RAM 2500 is no slouch either, pulling up to 20,000 pounds when properly equipped. With integrated trailer brake control, Trailer Reverse Steering Control, and 360° Surround View with Trailer Camera, hitching and hauling has never been easier.

Whether you’re navigating tight spots or hauling across long stretches of highway, RAM’s towing technology gives you the confidence to stay in control.

Payload Capacity: Built to Carry the Load

It’s not just about what you can tow—it’s also about what you can haul. The 2026 RAM 3500 delivers a maximum payload capacity of 7,680 pounds, while the RAM 2500 offers up to 4,000 pounds in the bed.

Combined with available cargo-view cameras, LED lighting, and the RamBox® Cargo Management System, your truck bed works just as hard as the engine.

Fuel Efficiency: Smarter Strength

Heavy-duty trucks aren’t about sipping fuel, but RAM makes sure you get the most out of every gallon. Thanks to advanced transmissions, variable valve timing, and efficient diesel engineering, the 2026 RAM Heavy Duty lineup balances power with smart fuel use.

• Gas engines average around 14–17 MPG highway (depending on load and configuration).
• Diesel models stretch further, averaging 17–22 MPG highway under light towing conditions.

RAM’s eTorque system (standard on the 1500) isn’t featured here, but engineering refinements across the heavy-duty lineup make sure your powertrain runs efficiently without sacrificing muscle.

Drivetrain and Handling: Confidence on Any Terrain

Performance isn’t just about what’s under the hood—it’s about how the truck handles the job. The 2026 RAM Heavy Duty lineup delivers:

• 4×4 capability with multiple drive modes for traction in mud, snow, or rocky terrain
• Available limited-slip differential and locking rear axle for added grip
• Class-exclusive Auto-Level Rear Air Suspension for stability under heavy loads
• Smooth ride quality thanks to coil-spring rear suspension on the RAM 2500

This means you’re not just pulling weight—you’re pulling it with confidence.

Advanced Performance Technology

The 2026 RAM Heavy Duty is more than raw power. It’s smarter, too, with tech designed to make tough jobs easier:

• Trailer Reverse Steering Control lets you guide your trailer with a simple knob
• Integrated Trailer Brake Controller keeps stopping smooth and safe
• Tow/Haul mode adjusts transmission shifts for heavy loads
• Hill Descent Control for controlled downhill travel
• Surround View Camera with Trailer View for easier hitching and reversing

RAM combines innovation with capability, ensuring you don’t just get the job done—you get it done safely and with less stress.

Performance Compared to the Competition

Ford and Chevy both bring serious competition in the heavy-duty market, but RAM continues to lead with:

• Best-in-class standard gas horsepower
• Class-leading diesel torque with the High-Output Cummins®
• Exclusive rear air suspension for improved ride comfort
• Upscale cabin and tech features that blend work and luxury

For drivers who want the best mix of brute strength and everyday livability, the RAM Heavy Duty edges ahead.
