The HD Ram comes in Tradesman, Big horn, Laramie, Rebel/Power Wagon, Limited Longhorn, Limited. Two engines are available 6.4L V8 405 horsepower and a diesel 6.7L intercooled turbo 6-cylinder 430 horsepower mated to an 8-speed automatic transmission.
Ram HDs can be ordered with either rear-wheel drive or 4-wheel drive. In 4-wheel-drive models, a front-axle disconnect system can help improve fuel economy. The Ram 3500 utilizes a Hotchkiss leaf-spring rear suspension, while 2500s have replaced leaf springs with a 5-link coil spring setup. Front suspension is now courtesy of a 3-link system. 2500s can be optioned with heavy-duty air suspension in place of the coil springs, which allow for driver-controlled load-leveling with precise, individual adjustment. Leaf-sprung 3500 dual-rear-wheel trucks with maximum tow packages also feature the air suspension system.
Ram understands that its trucks must last a lifetime. To stand behind them, Ram offers a 5-year or 100,000 miles warranty for diesel powertrains and 5-year or 60,000 miles for the gas powertrain.
On the interior, Ram HD trucks have been reconfigured to provide increased creature comforts. Available amenities include soft-touch instrument panels and door trim, 2-tone upholstery and contrasting stitching. Wood and metal inlays accent the interior and a largest-in-class 12-inch full-color touchscreen display serves as central command for the Ram HD. Heated and ventilated seating and a heated steering wheel are also available. Buyers can choose between bucket seats or a 40/20/40 bench configuration. In either case there's a multi-media port in the center with USB, SD and auxiliary inputs.
Each Ram HD offers a different set of interior appointments and equipment that can be tailored to fit basic work needs or provide a relatively luxurious cabin. Two different UConnect systems with the 12-inch touchscreen are offered both with Bluetooth hands-free connectivity. The top system also provides wireless Internet connectivity, as well as HD Radio and SiriusXM compatibility.
These are some of the standard equipment on the base Trademan trim, 17-inch steel wheels, cruise control, tilt adjustable steering wheel, Class V hitch receiver, seven pin harness, push button start, front vinyl bench seat, 5-inch touchscreen infotainment, 6-speakers, rear camera, and 5 USB ports.

The 2025 Rebel HD and Power Wagon offers an off-road-focused model that features a lifted suspension, skid plates, and an electronically locking rear differential. The Rebel is offered exclusively on the 2500 model, four-wheel drive is standard. The Rebel 2500 shares much of the Power Wagon's undercarriage, including its three-link live-axle front suspension, five-link coil-sprung rear axle with a limited-slip differential and electronic locker, skid plates, and 33-inch off-road tires. Styling is largely derived from the Power Wagon, but the Rebel gets a unique Mopar power-bulge hood. The Power Wagon standard equipment list includes its 2-inch suspension lift, 17-inch bead-lock-capable wheels, lockable front differential, and the Articulink front suspension with its detachable front anti-roll bar. Also, the Power Wagon's standard 12,000-pound Warn winch is an option on the Rebel. HD Rebel offers a few critical options you can't get on a Power Wagon, including one that is nothing more than legendary, The Cummins 6.7-liter, six-cylinder turbodiesel. The Rebel also comes with a set of stiffer springs found on other HD rams and an optional rear air suspension.
The Limited Longhorn tops the Laramie with more luxury features, such as rain sensing wipes, projector beam headlamps, LED bed lighting, spray-in bedliner, remote tailgate release, ambient lighting, premium leather interior, bucket ventilated front seats, driver seat memory, and integrated navigation with voice activation.
The most luxurious Limited adds 20-inch wheels, power running boards, wireless charging pad, 12-inch touchscreen infotainment, RamBox (short bed only), and blind spot monitor with rear cross traffic alert.
The Ram 2500 and 3500 both carry over with minimal changes for 2025.
Ram 2500 models are built to handle the most extreme towing tasks, while the 3500 models are aimed at commercial use and marketed towards ranchers and construction crews. Even compared to other automakers' heavy-duty trucks, the Ram 2500 and 3500 HD models have some of the best-appointed, most luxurious and most attractive interiors available in any pickup.
