Our product line consists of a wide variety of sizes and configurations. We have the ability to manufacture any type of guide needed to fit your specific, individual application. These quality guides are made from severe duty bronze and are designed for long life in “after-market” cylinder heads. For the serious racer, CHE Precision offers an “XP” (Extra Precision) series valve guide, which is used by the industry’s top racing teams. These are made from a special formulation of HT Bronze, developed from over 25 years of extensive research and experience in the racing industry. This particular bronze was specifically developed to provide extended wear properties and extraordinary heat dissipation.
