The 2026 RAM 3500 Big Horn Crew Cab 4x4 8 Box is a machine built for those who demand uncompromising strength without sacrificing the comforts of a modern mobile office. Imagine heading out from your home in Riverside, CA, with a heavy trailer in tow, feeling the confidence of a truck engineered to dominate the steep grades and open highways of the Inland Empire. Whether you are hauling equipment to a job site in Fontana, CA, or preparing for a weekend getaway with a massive fifth-wheel camper, this RAM 3500 provides the stability and presence required for the most demanding tasks.

Performance & Capability

Under the hood of this Bright White Clearcoat powerhouse lies the legendary Cummins High Output 6.7L I-6 diesel direct injection engine. This intercooled turbo diesel powerplant delivers a staggering 430HP, providing the raw mechanical force needed to move heavy loads with ease. Paired with the 8-Speed TorqueFlite HD Automatic Transmission, the drivetrain is optimized for smooth power delivery and durability. The Four Wheel Drive system features a part-time 4WD transfer case, allowing you to engage extra traction exactly when the terrain demands it.

To ensure long-term reliability in varying climates, this truck includes an ENGINE BLOCK HEATER and heavy-duty engine cooling. The Mechanical limited slip differential and 3.42 Axle Ratio work in harmony to provide consistent grip, whether you are navigating the suburban streets of West Covina, CA, or traversing loose gravel on a remote work site. Drivers can monitor every aspect of the powertrain through the Engine hour meter, Transmission fluid temperature gauge, and Turbo/supercharger boost gauge, ensuring you are always aware of the vehicle's vitals during heavy use.

Technology & Connectivity

The interior of this Big Horn is centered around the impressive RADIO: UCONNECT 5 NAV W/12.0 INCH DISPLAY. This massive touchscreen serves as the hub for all your media and navigation needs, featuring Integrated navigation system with voice activation to help you find the most efficient routes. With Apple CarPlay and Android Auto smart device wireless mirroring, your favorite apps and contacts are always within reach without the clutter of cables.

Connectivity is a priority in this Crew Cab, featuring 5 USB ports and a Remote USB Port - Charge Only to keep every passenger's devices powered. The Alexa Built-In virtual assistant allows for hands-free commands, while the 9 Alpine Speakers w/Subwoofer provide a premium audio experience for your daily commute. For those who need to stay connected on the move, the 4G LTE Wi-Fi Hot Spot capability transforms the cabin into a functional workspace, no matter where your projects take you.

Comfort & Interior

Inside the spacious cabin, you are greeted by a refined Black interior featuring Premium cloth front seat upholstery. The 40/20/40 Split Bench Seat configuration offers versatility, while the Power Adjust 8-Way Driver Seat with Power 2-Way Driver Lumbar Adjust ensures you remain comfortable during long stints behind the wheel. On chilly mornings, the HEATED SEATS & WHEEL GROUP provides immediate warmth through the Heated Front Seats and Heated Steering Wheel.

Practicality is woven into the design with Folding Flat Load Floor Storage, Front Center Seat Cushion Storage, and 2nd Row In Floor Storage Bins. The Dual-zone front climate control allows both the driver and passenger to set their preferred temperatures, while Rear under seat climate control ducts keep those in the back comfortable. Every detail, from the Piano black and chrome interior accents to the Leatherette steering wheel, has been selected to create an environment that feels both rugged and upscale.

Safety & Driver Assistance

Safety in a vehicle of this size is paramount, and the 2026 RAM 3500 is equipped with a comprehensive suite of protective technologies. The Surround View Camera System provides an aerial view of the truck, making it significantly easier to navigate tight parking lots or hitch up a trailer. This is complemented by the ParkSense front and rear parking sensors and the Back-Up Camera. For highway driving, the Adaptive Cruise Control with stop and go and Forward Collision Warning-Plus provide an extra layer of awareness.

The BLIND SPOT & CROSS PATH DETECTION system is specifically designed to account for the length of the vehicle, providing alerts when vehicles enter your hard-to-see zones. Additional safety features include Pedestrian/Cyclist Emergency Braking, Electronic stability control with anti-roll, and a total of 6 airbags. The Trailer brake controller and Trailer Reverse Guidance ensure that when you are towing, you have maximum control and visibility of your cargo at all times.

Exterior & Design

The exterior of this RAM 3500 makes a bold statement with its Bright White Clearcoat finish and Sport Appearance Package, which includes a body-color grille surround and painted front and rear bumpers. This model is configured with Dual Rear Wheels and 17 inch Polished Aluminum Wheels, providing the wide stance and increased payload capacity necessary for heavy-duty applications. The 8 Box provides ample room for cargo, protected by a MOPAR spray-in pickup bed liner.

Functionality is enhanced by LED Headlights, LED front fog lights, and LED Tail Lamps, ensuring excellent visibility in all weather conditions. The 5TH WHEEL/GOOSENECK TOWING PREP GROUP means this truck is ready for the biggest trailers right from the start. Practical touches like the MOPAR Deployable Bed Step, Power Telescoping Mirrors, and LED in-box lighting demonstrate that this truck was designed by people who understand the needs of truck owners.
