The ARP 207-5401 Main Stud Kit is engineered to provide the clamping force necessary to prevent main cap walk and ensure bottom-end stability under extreme boost and high-RPM conditions. Manufactured from premium 8740 chromoly steel, these studs are heat-treated and precision-machined to exceed OEM specifications.
