Countless hours of research and development is performed in order to complete a set of cams that meets the Tomei standard. The end result is a high quality product that produces effective and reliable results.

Every cam is engineered on super precise CNC machines and incorporate magnesium phosphate coating to prevent direct contact with other valvetrain components. Additionally, every cam lobe is treated with a ‘wavy groove’ to promote oil lubrication and prevent cam locking.
