Continuing a relationship that extends through numerous Martelli Brothers events, California 300 officials are pleased to announce that Assault Industries will once again be the Official Trophy Sponsor of this year’s event. Top finishers in the 2023 California 300, returning to Barstow, California on October 4-8, will once again receive custom-built trophies from Assault, while fans and racers alike will get to see both the trophies and Assault Industries UTV accessories on the Start/Finish Line Midway all race week long.

“Again and again, Marcelo and the Assault Industries team manage to outdo themselves on our race trophies, and we feel this year’s California 300 will be no exception,” said California 300 CEO Matt Martelli. “The care they put into designing our winner’s hardware is only matched by the design and durability of their off-road accessories.
