2026 Ram Heavy Duty near Elizabethton, TN

The 2026 Ram Heavy Duty lineup includes the Ram 2500 and Ram 3500 in Regular Cab, Crew Cab, and Mega Cab configurations with available 4x2 and 4x4 drivetrains. The platform uses a longitudinal front-engine layout with a ladder-type frame, steel cab construction, and a double-wall steel pickup box. Ram builds the heavy-duty lineup at the Saltillo Truck Assembly Plant in Coahuila, Mexico. The truck range is engineered for towing, hauling, payload management, off-road capability, and long-distance transport applications through multiple powertrain, suspension, axle, and chassis configurations.

Heavy-Duty Engine Configurations Designed for High Output

The standard gasoline engine in the 2026 Ram Heavy Duty lineup is the 6.4-liter HEMI® V-8. This 90-degree gasoline V-8 uses variable cam timing and displaces 392 cubic inches, or 6,417 cubic centimeters. Bore and stroke measurements are 4.09 inches by 3.72 inches. The engine uses pushrod-operated overhead valves with 16 valves, eight deactivating lifters, and eight hydraulic lifters equipped with roller followers.

The HEMI® V-8 produces 405 horsepower at 5,600 rpm and 429 lb-ft of torque at 4,000 rpm. The maximum engine speed is electronically limited to 5,800 rpm. Fuel delivery comes through a sequential multiport electronic returnless fuel injection system. Engine construction includes a deep-skirt cast-iron block with cross-bolted main bearing caps and 356 aluminum cylinder heads with hemispherical combustion chambers. The compression ratio is rated at 10.0:1.

The engine operates on 87-octane unleaded regular gasoline. Oil capacity measures 7.0 quarts, while coolant capacity is 16.6 quarts. Emissions equipment includes three-way catalytic converters, heated oxygen sensors, cooled electronic exhaust-gas recirculation, and individual cylinder fuel control systems.

The available 6.7-liter Cummins® Turbo Diesel I-6 high-output engine uses an inline six-cylinder layout with turbocharging and intercooling. Total displacement measures 408 cubic inches, or 6,690 cubic centimeters. Bore and stroke dimensions are 4.21 inches by 4.88 inches. The diesel engine uses pushrod-operated overhead valves with 24 valves and hydraulic lifters.

Output ratings reach 430 horsepower at 2,800 rpm and 1,075 lb-ft of torque at 1,800 rpm. Maximum high-idle engine speed is 3,200 rpm. The engine uses electronic high-pressure common-rail fuel injection and a compacted graphite iron block paired with a cast-iron cylinder head. The compression ratio measures 16.2:1.

The diesel engine operates using ultra-low-sulfur diesel fuel. Oil capacity is rated at 12.0 quarts with filter, and coolant capacity measures 23.8 quarts. Emissions control systems use selective catalytic reduction technology.

Eight-Speed Automatic Transmission Systems

The 2026 Ram Heavy Duty lineup uses ZF TorqueFlite HD eight-speed automatic transmissions across both gasoline and diesel applications. The 6.4-liter HEMI® V-8 pairs with the TorqueFlite HD 8HP75 automatic transmission. The 6.7-liter Cummins® turbo diesel pairs with the TorqueFlite HD 8AP1075 automatic transmission.

Both transmissions use adaptive electronic control systems and support automatic operation or Electronic Range Select manual gear control. The transmission design uses five clutch packs with only two open clutches in any gear. A torque converter lockup system with a turbine torsional damper supports low lockup speeds through first to eighth gears.

Gear ratios remain identical across both transmission variants. First gear uses a 4.71 ratio, second gear uses 3.14, third gear uses 2.10, fourth gear uses 1.67, fifth gear uses 1.29, sixth gear uses a direct 1.00 ratio, seventh gear uses 0.84, and eighth gear uses 0.67. The reverse gear ratio measures 3.30.

The gasoline-powered configurations use available axle gear ratios of 3.73 and 4.10. Diesel-powered models use a 3.42 axle ratio.

Four-Wheel Drive Transfer Case Systems

The 2026 Ram Heavy Duty lineup offers several transfer case configurations for 4x4 models. Trucks equipped with the 6.4-liter HEMI® V-8 use the BW 44-46 or BW 44-47 transfer case systems. These systems operate as part-time electric-shift transfer cases with selectable 2WD, 4WD High, Neutral, and 4WD Low modes.

Models equipped with the high-output 6.7-liter Cummins® diesel engine use the BW 44-48 transfer case. This transfer case also operates as a part-time electric-shift system with identical operating modes.

All listed transfer cases use a 2.64 low-range ratio. None of the systems includes a center differential.

Axle Construction and Structural Components

Front axle equipment on 4x4 models includes an AAM 9.25-inch beam front axle with center disconnect functionality. Power Wagon® models include locking differentials for additional traction management during low-grip operation.

Rear axle configurations vary by model. Ram 2500 and Ram 3500 models use an AAM 11.5-inch beam rear axle. Ram 3500 Max Tow configurations upgrade to an AAM 12.0-inch beam rear axle.

Suspension Architecture for 2500 and 3500 Models

The 2026 Ram 2500 uses a three-link front suspension with a track bar, coil springs, a stabilizer bar, and a solid axle design. Four-Wheel Drive Power Wagon® models add a disconnecting sway bar system.

Rear suspension on the Ram 2500 uses a five-link design with a track bar, coil springs, a stabilizer bar, and a solid axle. Optional airbags are available on certain 4x4 configurations.

The Ram 3500 uses a three-link front suspension with a track bar, coil springs, a stabilizer bar, and a solid axle arrangement. Rear suspension systems use two-stage longitudinal leaf springs with a solid axle. Supplemental airbags are available as an option.

Brake Systems and Steering Hardware

Front brake assemblies on the 2026 Ram Heavy Duty use 14.17-inch by 1.54-inch disc brakes with twin-piston pin-slider calipers and antilock braking systems. Rear brake assemblies use 14.09-inch by 1.34-inch disc brakes with twin-piston pin-slider calipers and ABS functionality.

Power assist systems differ between models. The Ram 2500 gasoline models use a dual-rate tandem diaphragm vacuum-assist system. Ram 2500 diesel models and all Ram 3500 models use hydro-boost brake assist systems.
Steering uses a hydraulic-assist configuration across the lineup.

Electrical Systems and Charging Components
