- Brand: ARP
- Part Number: ARP-218-4702
- Country of Manufacture: United States
ARP Pro Series head studs are engineered for professional engine builders demanding the highest level of reliability and performance. Manufactured from premium grade 8740 alloy and proprietary ARP2000 alloy, these studs offer tensile strengths of 190,000 psi (8740) and 220,000 psi (ARP2000), exceeding typical "aircraft" quality standards. Each stud is heat-treated individually for consistent strength and durability.
Precision manufacturing ensures exact tolerances, allowing gaskets and cylinder heads to align perfectly during assembly. This results in a smoother installation process and superior clamping force compared to conventional bolts. The use of studs, rather than bolts, minimizes distortion and provides more accurate and consistent torque loading, as the stud stretches only along the vertical axis when torqued.
ARP head studs are centerless ground and thread rolled after heat-treatment for maximum fatigue strength. This attention to detail ensures long-term reliability, especially in engines that are serviced frequently or subjected to high-performance conditions.
ARP is recognized as a leader in fastener technology, supplying high-performance hardware for professional motorsport and OEM applications worldwide.
