With over one hundred years of precision manufactured Cast-iron piston rings, members of Grant family have been building and racing cars for generations. “Running their flathead ’32 Roadster at the dry lakes, the brothers (Grant and Dick MacCoon – nephews to founder Gerry Grant) gained knowledge in the fact that a piston ring was more than just decoration for a piston. They realized how important the ring was for sealing and helping to dissipate heat under tremendous cylinder pressure.”
