Replace your cylinder head bolts with high-strength ARP head studs for improved head gasket sealing under the most demanding racing conditions!
Cylinder head studs provide more accurate and consistent clamping force because the fastener does not twist when you apply your torque wrench. This means more reliable head gasket sealing, particularly in high-compression applications. Studs only get installed once (rather than at every rebuild), which reduces the chances of damage to the female threads in the block. Head studs also help to locate the head gasket and cylinder head, which can mean faster rebuilds or trackside servicing.
ARP cylinder head studs are made from 8740 chrome moly steel, heat-treated to 200,000 psi tensile strength with J-form threads that are rolled (not cut) after heat treatment (not before) for unmatched strength and precision.
This set fits the Audi 2.7L V6 twin turbo engine (1999-2002 Audi B5 S4 / RS4 Quattro). Includes sixteen M11 cylinder head studs, matching nuts, and a packet of ARP assembly lube.
Note: The star-drive nuts in this kit require a special ARP Head Bolt Socket for Audi 2.7L V6 Biturbo, Part No. ARP920-0002 (sold separately).
