Viva Chassis traces its roots to the late 1960s, born from a passion for speed, adventure, and the rugged spirit of off-road racing. Our founder, a San Diego native, was first introduced to the world of off-roading during his service in Vietnam, where the thrill of traversing challenging terrain sparked a lifelong obsession. Returning home, he found himself captivated by the emerging off-road scene, particularly the legendary Baja 1000, which quickly became the "off-road Indy 500" for a new generation of racers

As orders increased, Viva Broncos (the original name) expanded operations to a rented garage, producing hand-formed flares, hoods, and other custom parts. The business thrived on personal relationships and a shared love of the sport, delivering parts directly to racing icons and learning from the best in the industry. The early 1970s marked a golden era for off-road racing, and Viva Broncos was at the heart of it—supporting teams, building vehicles, and innovating new products for the growing community

From 1969 to 1975, Viva Broncos was deeply involved in the Baja racing scene, fielding teams, managing pit crews, and overcoming the logistical challenges of desert endurance racing. The company’s vehicles and parts were tested in the harshest conditions, leading to constant improvements and a reputation for durability and performance. The founder’s own Bronco, "Hot Ginger," became a fixture at races, and the shop’s after-race gatherings were legendary for their camaraderie and storytelling

In January 2024, Viva Chassis kicked off the highly anticipated VIVAZILLA project—a bold step forward in performance and customization. The VIVAZILLA lineup includes everything from bare frames and four-link coilover suspension setups to rolling chassis, full chassis builds, and complete vehicle builds. At the heart of the project is the powerful VIVAZILLA engine, designed as a drop-in solution for virtually any application you can dream of. Customers can also rely on Viva Chassis to help source the right transmission and transfer case to complete their setup. While the Whipple Supercharger is an exciting optional upgrade, every VIVAZILLA engine comes standard with the Indy Power Products front accessory drive and a KMF oil pan—raising the bar for performance and reliability across the board.
