Proudly Made in the USA
Here at AFR you won’t find cheap parts made overseas. All of our castings, parts, and manufacturing is sourced and machined here in the United States (baring valves). This small perk is more important than ever considering the current state of affairs we are faced with here in our country. The only exception is our extremely high quality one piece stainless valves which are manufactured in a state of the art world class factory in Argentina. For our intake valves we use 21-4N material and for our exhaust valves we use 23-8N stainless which has superior properties for dealing with the excessive heat the exhaust valve is constantly subject to. Again our competitors cut corners here risking your expensive engines by saving a few bucks on cheaper materials.
