Whether you are hauling heavy equipment to a job site in Riverside, CA or preparing for a weekend of equestrian activities in the wide-open spaces of Norco, CA, the 2026 RAM 3500 Big Horn Crew Cab 4x4 8 Box is designed to handle the heavy lifting of your daily life. This truck isn&39;t just a vehicle; it is a mobile headquarters for the hardworking professionals and active families who keep the Inland Empire moving. With its massive 8-foot box and rugged 4x4 capability, it bridges the gap between a dependable workhorse and a comfortable family sanctuary, ensuring you never have to choose between capability and community values. Performance & Capability At the heart of this powerhouse is the Cummins High Output 6.7L I-6 diesel direct injection engine, a legendary powerplant delivering 430HP and the kind of low-end grunt required for the most demanding tasks. This iron-block engine is paired with the 8-Speed TorqueFlite HD Automatic Transmission, featuring a Lock-up transmission and Overdrive transmission for optimized efficiency and smooth power delivery. Whether you are navigating the suburban grades of Claremont, CA or maintaining steady speeds on the 10 freeway, the Selectable mode transmission and Engine retarder system provide exceptional control over your load. The mechanical foundation is built for durability, utilizing a Rigid axle front suspension with a Multi-link setup and a Leaf spring rear suspension to maintain stability under heavy payloads. The Part-time 4WD system and Mechanical limited slip differential ensure that when the pavement ends or the weather shifts, your traction remains absolute. For those managing a fleet or a small business, the Engine hour meter and Transmission fluid temperature gauge allow for precise maintenance tracking, ensuring your investment stays on the road longer. This RAM 3500 also features Dual 730 Amp Maintenance Free Batteries and Heavy Duty Engine Cooling to handle the heat and electrical demands of a professional-grade workspace. Technology & Connectivity In todays fast-paced environment, staying connected is a necessity, not a luxury. This RAM 3500 is equipped with the Radio: Uconnect 5 Navigation with 12.0-inch Display, providing a massive, clear interface for all your essential apps. With Apple CarPlay and Google Android Auto integration, you can seamlessly mirror your smartphone for hands-free calls, messaging, and music. The Integrated navigation system with voice activation ensures you find the most efficient routes through the Inland Empire, while SiriusXM with 360L keeps the cabin entertained during long hauls. The tech experience extends to the drivers view with a Cluster 7.0-inch TFT Color Display, providing vital vehicle information in high resolution. To keep your devices powered throughout the workday, the interior features a Dual Wireless Charging Pad and a Media Hub with 2 Charge Only USBs, contributing to a total of 9 USB ports throughout the cabin. With Handsfree Uconnect w/Bluetooth and Steering Wheel Mounted Audio Controls, you can manage your communications and media without ever taking your eyes off the road or your hands off the wheel. Comfort & Interior The cabin of the 2026 RAM 3500 Big Horn is a refined retreat from the rigors of the job site. Featuring Black Premium cloth front seat upholstery, the interior is both durable and welcoming. The Power Adjust 8-Way Driver Seat with Power 2-Way Driver Lumbar Adjust allows you to find the perfect position for long commutes, while Heated Front Seats and a Heated steering wheel provide immediate comfort on those chilly early mornings. The Dual-zone front climate control ensures both you and your passenger stay at your preferred temperatures regardless of the California sun. Practicality is woven into every inch of the interior. The Rear 60/40 Folding Seat and Folding Flat Load Floor Storage allow you to transition from carrying a crew to hauling sensitive gear inside the cab. You will also find 2nd Row in Floor Storage Bins and a Full Length Upgraded Floor Console to keep your tools and personal items organized. For added convenience, the Power Adjustable Pedals and Auto Power-Folding Mirrors make it easy for different drivers to get comfortable quickly.

Safety & Driver Assistance Safety is paramount, especially when operating a vehicle of this magnitude. This RAM 3500 is outfitted with a Surround View Camera System, giving you an aerial view of the truck to make navigating tight parking lots in West Covina, CA or backing into a narrow driveway much safer. The Blind Spot and Cross Path Detection system provides an extra set of eyes when changing lanes with a trailer, while Forward Collision Warning-Plus and Front Collision Mitigation work to prevent accidents before they happen. Additional peace of mind comes from the Active Lane Management System and Adaptive Cruise Control with stop and go, which reduce driver fatigue during heavy traffic. For those who tow frequently, the Trailer Tire Pressure Monitoring System and CTR Stop Lamp w/Cargo View Camera allow you to keep a constant watch on your cargo and equipment. The truck is also equipped with Drowsy Driver Detection and an Emergency Vehicle Alert System (EVAS), showcasing a modern approach to driver awareness and community safety. Exterior & Design Dressed in Diamond Black Crystal Pearlcoat, this RAM 3500 commands attention with the Night Edition package. This aesthetic upgrade includes a Body Color Grille Surround, Gloss Black Nostrils, and Black Exterior Truck Badging for a sophisticated, rugged look. The 17-inch Black Machined Aluminum DRW Wheels and Dual Rear Wheels not only provide the necessary stability for heavy hauling but also contribute to the trucks aggressive stance. Functionality is built into the exterior with LED Headlights, LED Tail Lamps, and LED front fog lights ensuring maximum visibility. The MOPAR Spray in Bedliner protects your 8-foot box from the wear and tear of daily use, while LED Bed Lighting and Forward and Reverse Utility Lights make it easy to work after dark.
