About Silver Seal Products Co., Inc.

Silver Seal Products Co., Inc.
In 1959, E.L. "Spike" Havens understood the need for a product that would enable engine builders to renew the life of worn valve springs. Spike invented, patented, and launched the manufacturing of the VSI, the Valve Spring Insert. Designed with heat slashing serrations, VSI still remains a truly unique product in today's market. It is the primary element on which Silver Seal Products Co. has advanced to the forefront.
