ARP studs are precision-engineered engine fasteners, also sold as head studs, engine studs, or high-strength stud fasteners. They are designed to replace factory bolts and studs in demanding engine builds. ARP (Automotive Racing Products) is known for fasteners made for racing, performance, and heavy-duty use.
