Granatelli Motor Sports is a name synonymous with American speed, performance, and engineering excellence. With a legacy spanning more than 70 years, Granatelli is not just a performance parts manufacturer—we are a family-built institution rooted in the history of motorsports, driven by innovation, and trusted by racers, builders, and performance enthusiasts around the world.
Our journey began in the 1940s when three brothers—Joe, Vince, and Andy Granatelli—set out to change the face of American racing. What started with grassroots hot rod building in post-war Chicago quickly evolved into a motorsports empire. The Granatelli brothers became known for pushing boundaries, experimenting with new technologies, and living life at wide-open throttle. Their passion birthed the iconic STP brand, a company that revolutionized automotive additives and became a household name worldwide.
The Granatelli name gained legendary status through its high-profile involvement in IndyCar racing during the 1960s and 70s. Under Andy Granatelli’s leadership, the Granatelli STP teams brought unprecedented innovation to the
Indianapolis 500, including the legendary
Novi turbine-powered cars—machines that forever changed how engineers thought about speed and aerodynamics. Andy’s magnetic personality, combined with engineering brilliance, earned him a place in both the
Motorsports Hall of Fame of America and the
Automotive Hall of Fame.
From sponsoring legends like Mario Andretti and Richard Petty to dominating drag strips and oval tracks, the Granatelli brand earned its place at the heart of American motorsports. But more than fame, our legacy was built on results: faster lap times, stronger engines, and parts that didn’t just meet expectations—they shattered them.
In the 1990s, the next chapter of the story was written with the formation of Granatelli Motor Sports. Founded by JR Granatelli, son of Joe Granatelli, the company bridged the gap between old-school muscle and modern performance. With a sharp focus on computer-controlled engines and emissions-compliant upgrades, JR led the development of industry-first technologies in ignition systems, throttle bodies, electronic exhaust cutouts, and high-output coil packs. The Granatelli name once again became a driving force in innovation—this time in the aftermarket performance sector.
Today, under the leadership of JoJo Granatelli, the third generation is carrying the torch into the future. JoJo is a fabricator, builder, and digital-era motorsports visionary. He has re-energized the Granatelli Motor Sports brand, combining deep technical understanding with a creative flair that connects with both the street scene and the professional racing world. From modern muscle cars to wild turbo builds, JoJo is ensuring that Granatelli Motor Sports remains at the forefront of the performance world.
Based in our state-of-the-art 42,000 sq. ft. headquarters in Oxnard, California, Granatelli Motor Sports designs, engineers, tests, and builds performance products for racers, tuners, and gearheads who demand the best. Our commitment to quality, innovation, and performance is second to none.
