Grant Piston Rings began in 1922 during the time of the Ford Model T. Much of Grant’s original recognition came from its support and service to the California race car and hot rod industry.

From Streamliners to racing boats to Grant’s 1952 Ferrari that ran at the Indianapolis 500, Grant has always been involved in high-performance vehicles.
