ARP Head Studs for Nissan Silvia SR20DET

• Brand: ARP
• Part Number: ARP-102-4701
• Country of Manufacture: United States

ARP Pro Series head studs for the Nissan Silvia SR20DET are engineered for professional engine builders demanding ultimate reliability and performance. Manufactured from premium grade 8740 alloy and proprietary ARP2000 alloy, these studs are heat-treated to 190,000 psi (8740) and 220,000 psi (ARP2000), ensuring superior strength compared to standard “aircraft” quality steels.

Each stud is precisely heat-treated and centerless ground for exacting tolerances, resulting in perfect alignment of gaskets and cylinder heads. This meticulous process eliminates common issues found in lesser quality studs, such as improper alignment and uneven clamping force.

Using studs instead of bolts offers more accurate and consistent torque loading. Studs are installed hand tight, allowing them to stretch only on the vertical axis when torqued, which provides even clamping across the cylinder head. This is especially beneficial for engines that require frequent servicing and rapid assembly, such as in racing applications.

ARP is recognized as a leader in fastener technology, manufacturing all products in-house to ensure optimal quality control. These head studs are suitable for both high-performance OEM replacements and demanding motorsport applications.
