Valve Lifter Sets, R32-R34

High Strength Lightweight Corresponding to high lift camshaft Exchange to solid type   High Strength Chrome-Moly Steel + Cold ForgingWe adopt cold forging process to the high strength chro-moly steel. This enabled to reduce burden to the valves enormously while raising reliability at the super high RPM sharply. Carburizing Surface TreatmentThe surface was treated with the Carburizing process to increase the surface hardness which raises reliability for longer periods of time even in extreme conditions of performance engines. Carburizing is the process of increasing the carbon content in the metals surface through a heat process to implant carbon atoms into the crystal structure of the metal. This will result in a harder outer surface, while the core remains soft and tough. Suitable for High Lift CamshaftsIt is one of the most sufficient ways of making high performance engine to install the high lift camshaft. However, in some engines, it cannot be done to raise the lift without appl
