• Type A .060” – Copper colored. Corrects assembled height and compensates for reduced pressure from “grind-in” when using in-service valve springs.
• Type B .030” – Silver colored. Compensates for loss of spring pressure, especially on new springs due to “heat-set” during break-in period.
• Type C .015” – Black colored. For valve spring balancing.
