Enhanced Wear Resistance: The engine camshaft is made from durable grey cast iron, offering wear resistance and fatigue strength. Paired with high-strength lifters and rocker arms, it can withstand thousands of impacts per minute in the engine, reducing wear on the contact surfaces between the cam lobes and lifter pillars. Increased Strength: The cam, after high-frequency hardening, has higher density and hardness, enabling it to resist the corrosion of engine oil and coolant in harsh operating conditions. Restore Engine Performance: If your engine experiences common issues such as early wear on the camshaft journals or signal gears, along with the wear of hydraulic lifters and rocker arms, this lifters camshaft kit provides a one-stop solution.
