COMP Cams is the only aftermarket valve train company in America that provides a Pro Plasma Nitriding Service in-house. Nitriding is a process by which nitrogen is introduced into iron or steel, causing a material's surface hardness to be increased for improved initial and long-term wear characteristics. It is recognized by metallurgists worldwide as the best way to increase the hardness and lubricity of flat tappet cams to enhance break-in and durability. Don't get blinded by shiny surface finishing or heat-treating - nitriding has been race-proven around the world and documented to deliver superior results.
