2026 Ram 2500 Towing Capacity & Payload Guide — Fontana CDJR

The 2026 Ram 2500 is built for drivers who need real heavy-duty capability. Whether you’re hauling equipment across Fontana’s industrial corridors or towing a fifth-wheel trailer for a weekend getaway, this truck delivers the power, payload, and towing technology to handle the job with confidence. With a maximum towing capacity of 20,000 pounds when properly equipped, the Ram 2500 stands at the top tier of the three-quarter-ton segment.

Engine Options and Towing Performance

The 2026 Ram 2500 offers two powertrains, each paired with an 8-speed automatic transmission and engineered for different towing demands.

High-Output Cummins Turbo Diesel

The available High-Output 6.7-liter Cummins Turbo Diesel inline-six produces 430 horsepower and a Best-in-Class 1,075 lb-ft of torque. When properly equipped, this powertrain enables the Ram 2500 to tow up to 20,000 pounds — enough to handle large equipment trailers, heavy-duty boats, or substantial fifth-wheel travel trailers. The diesel’s high torque output at low RPMs provides strong pulling power on extended hauls and steep grades, making it the preferred choice for drivers near Rancho Cucamonga and San Bernardino who regularly tow at or near the truck’s maximum capacity.

6.4L HEMI V8

The standard 6.4-liter HEMI V8 generates 405 horsepower and 429 lb-ft of torque. When properly equipped, this engine delivers a maximum towing capacity of up to 17,750 pounds while also offering strong payload performance. For drivers in Riverside and Claremont who need a balance of towing strength and everyday drivability without the added maintenance considerations of a diesel, the HEMI V8 is a versatile and proven option.

Payload Capabilities and Real-World Applications

Payload — the maximum weight the truck can carry in its bed and cabin, including passengers, cargo, and equipment — is just as important as towing capacity for heavy-duty truck buyers. Understanding the difference between payload and towing is critical: towing refers to weight pulled behind the vehicle, while payload covers the load carried directly by the truck.

2026 Ram 2500 Payload by Engine and Drivetrain

*When properly equipped. Ratings vary by cab style, bed length, axle ratio, and equipment. The Ram 2500’s maximum Gross Vehicle Weight Rating (GVWR) reaches up to 11,040 pounds. Always check the door label and official tow rating charts for your specific configuration.

Overloading payload can compromise handling, braking, and suspension performance. Whether you’re transporting building materials to job sites around West Covina or carrying tools and crew across San Bernardino, staying within your truck’s rated payload ensures safe, efficient operation.

Class-Exclusive Auto-Level Rear Air Suspension

The 2026 Ram 2500 offers an available Class-Exclusive auto-leveling rear air suspension system that enhances ride quality and stability when hauling heavy loads. This system automatically adjusts the rear ride height to maintain a level stance regardless of cargo weight or trailer load, helping optimize handling, steering control, and braking performance under varying conditions.

When towing trailers or carrying heavy payloads, the rear of the truck can sag without proper support. The air suspension counteracts this by inflating or deflating air springs to keep the truck balanced, reducing body roll and improving driver confidence. The system also includes a Bed Lowering Mode, which lowers the rear height to simplify trailer hookups — a practical feature for drivers who frequently manage heavy equipment or cargo.

Combined with the Ram 2500’s class-exclusive five-link coil rear suspension, the chassis is engineered to deliver both heavy-duty strength and refined ride quality that sets it apart from competitors relying on traditional leaf spring setups.

Configuration Factors and Towing Technology

The Ram 2500’s maximum towing and payload ratings vary depending on several configuration factors. These variables mean that the “maximum” figures represent specific optimized builds — not every Ram 2500 on the lot will tow 20,000 pounds.

What Affects Your Towing and Payload Rating

For trailers exceeding 20,000 pounds, a fifth-wheel or gooseneck hitch is required. Additional towing technology — including electronic trailer sway control, available Trailer Reverse Steering Control, and an available 360-degree Surround View Camera system — helps drivers manage heavy loads with greater confidence and control.

Buyers should consult the vehicle’s door label and the official Ram tow rating charts to determine exact capacity for their chosen configuration.
