Ram 2500 vs. GMC 2500: Detailed Specs Comparison

Below, we’ve compared the Ram 2500 and the GMC Sierra 2500’s key specifications.

Engine Performance and Drivetrain

The GMC Sierra 2500 HD and Ram 2500 offer 2WD and 4WD options and two powerful engine choices to meet various performance needs.

Choose between the GMC turbo-diesel or gas-powered engines. The standard 6.6-liter V-8 gas engine produces 401 horsepower and 464 lb-ft of torque. Upgrade to the 6.6-liter Duramax turbo-diesel V-8 for a more robust performance; it generates 470 horsepower and 975 lb-ft of torque. Both engines mate with an Allison 10-speed automatic transmission.

The Ram 2500 features a standard 6.4-liter HEMI V-8 engine outputting 410 horsepower and 429 lb-ft of torque. There’s also a 6.7-liter Cummins turbo-diesel I-6 engine you can opt for if you need more power; it produces 370 horsepower and 850 lb-ft of torque.

Towing Capacities

Get the most out of your heavy-duty truck; its massive towing capacities are perfect for hauling a travel trailer for a fun family road trip or trailering your boat to a relaxing day on Lake Erie. The GMC Sierra 2500 offers a maximum 22,070-pound tow rating when equipped with the crew cab, long bed, 2WD, and turbo-diesel engine.

Add the Max Trailering package to your Sierra 2500 HD to improve towing overall. It provides a 12-inch rear axle, gooseneck or fifth-wheel prep, and bed-stamped holes with installed caps. There’s also a 3500 HD package with upgraded shocks, leaf springs, and frame. For even more convenience, the ProGrade trailer system provides hitch guidance with a hitch view and an in-vehicle trailer app for improved precision while driving and reversing with a trailer attached.

With its turbo-diesel engine, the Ram 2500 offers a maximum towing capacity of 19,990 pounds. The HEMI V-8 engine can only tow up to 17,730 pounds. Ram provides an available trailer reverse steering control for easier reversing with an attached trailer. It also offers live tire pressure readings on the available digital instrument cluster and a factory-installed rear-axle crossbar for a fifth-wheel/gooseneck prep.

Truck Bed and Cargo Capacity

The GMC Sierra 2500 has two bed lengths and capacities. The standard truck bed provides 69.50 cubic feet of cargo volume, and the long bed boasts 83.5 cubic feet. Whatever the length of your bed, loading and unloading is easy with the GMC MultiPro tailgate, which is either standard or available on select 2500 HD trims. This versatile six-function tailgate enhances your cargo loading experience and includes hitch area lighting and power lock and release features.

In comparison, the heavy-duty Ram truck has room for improvement. The Ram has a 6.4-foot box with 57.5 cubic feet of cargo volume or an 8-foot box with 74.7 cubic feet. However, Ram compensates for the smaller bed sizes by offering the optional RamBox cargo management system, which features two lockable, drainable storage bins with LED lighting and a driver-side 115-volt power outlet.

Cabin Configurations and Seating Capacity

Customize your heavy-duty work truck cabin to meet your seating capacity needs. The Ram 2500 and GMC Sierra Heavy Duty regular cab are ideal for seating three people. Consider the GMC’s double or crew cab options if you need to accommodate up to six people. The Ram 2500 crew cab can seat six with its 8-foot box, while the 6.4-foot box configuration seats five.

Select the GMC regular or crew cab for the best available headroom and legroom. These GMC 2500 HD cabin configurations provide 43.03 inches of front headroom, 44.53 inches of front legroom, 40.12 inches of second-row headroom, and 43.40 inches of second-row legroom.

The Ram truck’s best available headroom and legroom is in the mega cab. This cabin provides 40.9 inches of front legroom, 43.1 inches in the rear, 40.9 inches of front headroom, and 40.3 inches in the rear. While this is the most spacious Ram 2500 cabin, it only seats up to five.
