• Total system engineering
• State-of-the-art manufacturing
• Precise metallurgy and heat treating
• Exacting machining
• Scrupulous quality control

Valvetrain and its components are a perfect example of AFA’s Total System Engineering and Manufacturing. Exposed to combustion forces inside the cylinder and lubricant on the outside, this highly articulated system requires maximum precision and refined integration of each part in order to function as a whole. Reliability in this area is affected by many external factors. Reliability must be achieved through a careful application of engineering design, metallurgy and precision manufacturing.
