For this purpose, ARP head studs stand unmatched. Currently, there isn't a ready-made kit for the L15B7 engine, but by integrating select ARP components with custom-designed spacers, we've developed a solution that meets both our requirements and those of others.\u003cbr data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003eARP selects top-grade 8740 alloy for their studs, which undergoes a rigorous heat treatment process to reach a tensile strength of 200,000 psi, ensuring thorough heat penetration and a quality far surpassing that of inferior studs found in the market, which are often processed inadequately.\u003cbr data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003eAfter heat treatment, ARP takes the additional step of centerless grinding each stud to achieve unparalleled concentricity. This meticulous process, involving around ten fine adjustments, yields a product of exceptional straightness.\u003cbr data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003eMoreover, ARP's method of thread rolling the studs post-heat treatment significantly enhances their fatigue strength by approximately 1000% compared to those threaded before heat treatment, a prevalent but inferior industry method. Despite the higher cost due to the wear on tools, this process is a testament to ARP's commitment to excellence.\u003cbr data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003e\u003cstrong\u003eKey Features:\u003c\/strong\u003e\u003cbr data-mce-fragment=\"1\"\u003e- ARP head studs for unmatched reliability.\u003cbr data-mce-fragment=\"1\"\u003e- Made from 8740 chromoly steel with 12-point nuts for superior strength.\u003cbr data-mce-fragment=\"1\"\u003e- Includes a correctly sized spacer to ensure accurate torque application of the head studs.\u003cbr data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003e\u003cstrong\u003eBenefits:\u003c\/strong\u003e\u003cbr data-mce-fragment=\"1\"\u003e- Provides a higher clamping force to maintain seal integrity.\u003cbr data-mce-fragment=\"1\"\u003e- Offers enhanced resistance to head lifting in high-boost scenarios, ensuring engine durability and performance.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eApplications:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e2016 - 2021 Honda Civic 1.5T\u003c\/li\u003e\n\u003cli\u003e2017 - 2021 Honda Civic Si\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eWhat's In The Box?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e10 - ARP Headstuds\u003c\/li\u003e\n\u003cli\u003e10 - ARP Nuts\u003c\/li\u003e\n\u003cli\u003e10 - MAPerformance L15B7 Headstud Spacers\u003c\/li\u003e\n\u003cli\u003e1 - ARP Assembly Lube\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e*High-performance racing component.
