  • Colsibro valve guide set

Colsibro valve guide set suitable for 5/16" valves as fitted in TR2-4A & Morgan + 4 engines.

Colsibro is a high-copper alloy with small additions of nickel and silicon, which combine to increase the strength, hardness and wear resistance of the material. The material is vastly superior to phosphor bronze in this application. It is resistant to galling or nipping up in arduous working conditions. 

Please note that once fitted into the cylinder head honing will be required to ensure the correct fit for the valve, this is a simple task for a competent machine shop.
