Ultra4 Racing operates within the events services sector, organizing a distinctive off-road racing series built around unlimited four-wheel-drive vehicles that compete across rock crawling, high-speed desert racing, and short-course formats. The concept grew from the Griffin King of the Hammers event and has expanded into a national schedule featuring regional East and West championships and a three-race pro series. The organization is based in Temecula, California, and Ultra4 Racing is overseen by Hammerking Productions, which is based in Lake Arrowhead, California. The audience includes off-road racing teams, sponsors, venues, and fans seeking structured competition and exposure across multiple disciplinas. In the broader industry, Ultra4 Racing sits as a multi-discipline platform with a national calendar tied to regional championships and a pro series, within the events services and motorsports space. A notable development in 2023 was a partnership with Volta Power Systems to establish a technology demonstration hub for electric off-road racing at the King of the Hammers event in Johnson Valley.
