ARP 208-4304 Head Studs for Honda H22A4 VTEC
- Brand: ARP
- Part Number: ARP-208-4304
- Country of Manufacture: United States
ARP Pro Series head studs are engineered for professional engine builders seeking uncompromising strength and reliability. Manufactured from premium grade 8740 alloy and proprietary ARP2000 alloy, these studs are rated significantly higher than typical “aircraft” quality steels. Each stud is vertically placed in special racks and heat-treated to 190,000 psi for 8740 material and 220,000 psi for ARP2000 material, ensuring thorough heat penetration and consistent material properties.
Unlike lower quality alternatives, ARP studs are centerless ground and thread rolled after heat treatment, resulting in exceptional dimensional accuracy and surface finish. This precision allows gaskets and cylinder heads to align perfectly during installation, improving assembly and reducing the risk of misalignment.
Studs provide more accurate and consistent torque loading compared to bolts, as they are installed hand-tight and only experience stretch along the vertical axis during torque application. This results in more uniform clamping force across the cylinder head, which is critical for high-performance and racing applications that require frequent servicing and reliable sealing under extreme conditions.
ARP is recognized as a leader in fastener technology, with all aspects of manufacturing controlled in-house to ensure optimum quality.
