Valve guides can be manufactured from a variety of materials, but CHE’s Proprietary Blended Bronze Alloys have extraordinary wear resistance and greater thermal properties than all other bronze alloys tested. This material is excellent for extreme temperatures and high RPM engines. Our guides are manufactured for longevity and performance.

Using our Proprietary Blended Bronze Alloy materials in valve guides allows for a more predictable and consistent expansion rate. This will allow you to run tighter stem-to-guide clearances as tight as 0.0006”. A tighter valve keeps unwanted lateral valve movement under control, which in turn reduces wear on the guide, seat and valve face.
