ARP Cilinderkopbouten D16A9
ARP Pro Series cylinder head studs are cold-forged to ensure molecular integrity. They’re heat-treated prior to thread rolling and machining. ARP Pro Series kits are also available with 12-point nuts, and all studs come complete with hardened parallel washers for an even load distribution and accurate torque readings.
