All ARP rod bolts are heat-treated before grinding and thread rolling and have a large underhead radius for greater strength. Guaranteed to pass magnetic inspection testing, these bolts are nearly five times stronger than OEM bolts. They're used in applications ranging from stock replacement to Circle Track, marine, and drag racing engines.
