KPMI GUIDE MNG. BRZ. IN/EX +0.002

These Engine Builder valve guides have been designed with the price conscious builder in mind. Expect the same exacting KPMI tolerances, but with a reduced toughness / wear-ability when compared to premium C630 Nickel Aluminum Bronze valve guides. The softer Manganese guides are easily reamed, and then can be delicately finished with our high quality ball hones. Now, with any battery operated or electric drill you can ream and hone manganese valve guides in less time and in the absence of expensive honing equipment required to properly size tough Nickel Bronze guides. Additionally, these guides have been designed to be compatible with our uniquely designed guide installation and removal tools. A relief in the seal detail allows for driving force to be applied without causing deformation in harmful areas.
