COMP Cams Lifters 89842C-16 Tool Steel Lifters from COMP Cams are engineered from M2-grade Tool Steel for its hardness and ability to resist abrasion. Lighter weight but with the same strength as regular steel, these heavy-duty lifters are available in 3 different diameters, with each diameter available in a coated, non-coated and non-coated with EDM oiling hole version. The DLC (Diamond Like Carbon), multi-layer coating provides the lifters with extremely slick and hard surface properties, making them resistant to abrasive wear in extreme contact pressure environments and compatible with most any camshaft material. This wear resistant coating also lowers the amount of power required to run an engine's valve train, as well as lowering friction, heat and oil temperatures.
