2026 RAM 3500 Big Horn Crew Cab 4x4 8 Box: Heavy-Duty Performance Meets Inland Empire Versatility Imagine heading out before sunrise in Ontario, CA, the morning air crisp as you prep for a demanding day at the job site or a long-awaited weekend hauling the trailer out toward the San Bernardino Mountains. You need a truck that doesn&39;t just promise capability but delivers it with the rugged reliability that local professionals and families have depended on for generations. Whether you are navigating the growing commercial corridors of Riverside, CA or managing a property with livestock in the equestrian heart of Norco, CA, this 2026 RAM 3500 Big Horn Crew Cab 4x4 with the 8-foot box is engineered to be your most trusted partner. It balances the sheer muscle required for heavy-duty labor with the approachable, community-focused values of a vehicle designed to protect and provide for your family. Performance & Capability At the heart of this powerhouse is the Cummins High Output 6.7L I-6 diesel direct injection engine, a legendary powerplant that produces an impressive 430HP. This intercooled turbo diesel is built with a durable Iron engine block and features a Longitudinal mounted engine configuration designed for maximum cooling efficiency during those hot climbs through the Cajon Pass. Paired with the 8-Speed TorqueFlite HD Automatic Transmission, the delivery of power is smooth and decisive, whether you are stop-and-go commuting through West Covina, CA or maintaining steady speeds on the open highway. The Four Wheel Drive system is a Part-time 4WD setup, giving you the flexibility to engage extra traction exactly when the terrain demands it. To ensure you stay informed and in control, the dashboard features a Transmission temperature gauge, an Engine hour meter, and a Turbo/supercharger boost gauge. For those navigating steep descents with a heavy load, the Engine retarder system provides essential braking assistance, reducing wear on the 4-Wheel Disc Brakes. The mechanical foundation is rounded out by a Mechanical limited slip differential and a heavy-duty suspension featuring a Rigid axle front suspension and Leaf spring rear suspension, ensuring this RAM remains composed under the heaviest payloads. Technology & Connectivity In todays fast-paced world, staying connected is a necessity, not a luxury. This RAM 3500 is equipped with the Radio: Uconnect 5 Nav w/ 12.0-inch Display, providing a massive, high-resolution hub for all your communication and navigation needs. With Integrated navigation system with voice activation, finding a new job site in Claremont, CA or a weekend campsite is intuitive and hands-free. The system fully supports Apple CarPlay and Google Android Auto via Smart device wireless mirroring, allowing you to access your favorite apps and playlists without fumbling with cords. The tech suite extends beyond the dashboard with 9 USB ports and a Media Hub with 2 Charge Only USBs, ensuring every passengers device stays powered up. For the driver, the 7.0-inch Gauge cluster display provides vital vehicle stats at a glance, while Steering wheel mounted audio controls and Voice activated audio controls keep your focus where it belongs—on the road ahead. Youll also appreciate the Front wireless smart device charging pad, which keeps your workspace clutter-free while maintaining a full battery for your next call. Comfort & Interior Inside the cabin, youll find a refined environment that serves as a mobile office and a family sanctuary. The Black Premium cloth front seat upholstery is both durable and comfortable, featuring Bucket front seats with a Power Adjust 8-Way Driver Seat and Power 2-Way Driver Lumbar Adjust to keep fatigue at bay during long shifts. The Night Edition interior adds a sophisticated touch with Black Interior Accents and Piano black and chrome interior accents, proving that a work truck can also be a high-end space. Practicality is woven into every corner of the interior. The Rear 60/40 Folding Seat and Folding Flat Load Floor Storage allow you to transition from hauling a crew to protecting valuable tools from the elements. Comfort is further enhanced by Automatic climate control and Dual-zone front climate control, while the Heated front seats and Heated steering wheel are welcome additions for those early morning starts. With 2nd Row In Floor Storage Bins, Dual Glove Boxes, and a Full Length Upgraded Floor Console, there is a dedicated place for everything from your tablet to your work gloves. Safety & Driver Assistance Safety is paramount, especially when you are operating a vehicle of this magnitude. This RAM 3500 is outfitted with a Surround View Camera System, giving you an aerial view of your surroundings to make maneuvering in tight Ontario, CA parking lots or job sites much simpler. The Blind Spot & Cross Path Detection system acts as an extra set of eyes, providing alerts when vehicles are in your hard-to-see zones, while the Active Lane Management System helps keep you centered during long commutes. For added peace of mind, the Forward Collision Warning-Plus and Pedestrian/Cyclist Emergency Braking systems are designed to intervene if a potential impact is detected. This truck also features Adaptive cruise control with stop and go, which is a game-changer for navigating the heavy traffic often found in the Inland Empire. Additional safety tech includes Drowsy Driver Detection, ParkSense front and rear parking sensors, and a Trailer Tire Pressure Monitoring System, ensuring that both your truck and your trailer are operating safely at all times. Exterior & Design Dressed in Diamond Black Crystal Pearlcoat, this RAM 3500 makes a bold statement. The Night Edition package transforms the exterior with a Body Color Grille Surround, Gloss Black Nostrils, and Black Exterior Truck Badging, creating a sleek, monochromatic look that stands out in any setting. This model features Dual Rear Wheels (DRW) for maximum stability, mounted on 17-inch Black Machined Aluminum Wheels. The exterior is as functional as it is stylish. The 8-foot box is protected by a MOPAR spray-in pickup bed liner and features LED in-box lighting for working after dark.
