Description
ARP head studs replace the factory torque-to-yield head bolts with reusable, precision-made studs that deliver higher, more consistent clamping force. They are the go-to upgrade for keeping the heads sealed and preventing head-gasket failure on modified, high-boost or rebuilt diesels. Studs thread into the block by hand, so all torque is applied on one axis for accurate preload, and the block threads are spared from repeated bolt cycles.
