ARP is the go-to manufacturer in the automotive industry for engine fasteners. Whether it be OEM replacement parts or custom hardware, their dedication to consistent top-notch quality has made them a favorite in the racing world.
These ARP head studs for Audi 20V 5 Cylinder engines are made from premium grade 8740 alloy steel which is rated far superior to many "aircraft" quality competitors. The studs are heat treated to 200,000 psi then thread rolled afterward, giving them twenty times better fatigue strength over studs threaded prior to treatment (a common practice with lesser quality studs). These high-quality head studs will ensure your head gasket stays firmly planted under even the most extreme boost conditions. These parts are great for race engines, manufactured in the U.S.A. and 100% re-usable.
