ARP

ARP manufactures fasteners, including head studs and rod bolts, to tolerances and material specs that exceed factory hardware. We carry their kits, including our Esse Werks collaboration bolt sets, for engines being assembled or re-torqued to handle sustained boost.
WHY WE SHIP ARP
ARP makes the fasteners that hold a build together when cylinder pressure climbs past what the factory hardware was torqued for. Head studs and rod bolts are not where you save money on a high-boost engine, because a stretched factory bolt or a lifted head gasket ends the build. We use ARP hardware because the material spec and the documented clamp loads are consistent part to part, which is exactly what you want in the component you never want to think about again. On any engine going for serious power or a fresh bottom-end assembly, this is the baseline hardware we build on.
