Known for head studs and head bolts, ARP is the go-to fastener when failure is not an option. Main studs, cylinder head bolts or wheel studs are all critical components where unexpected stretching can result in a detrimental failure. ARP features premium grade 8740 alloy that is a far superior material selection for this application versus a supposed "aircraft" quality product.
