{"product_id":"8740-chromoly-head-stud-kit-1","title":"8740 Chromoly Head Stud Kit","description":"The ARP Head Stud Kit is engineered to ensure robust head-to-block sealing in high-performance, low-displacement 4-cylinder engines. Constructed from top-grade 8740 chromoly steel, each stud undergoes rigorous heat treatment to achieve a tensile strength of 200,000 psi, surpassing lesser-quality studs. ARP's meticulous process includes centerless grinding for exceptional straightness and thread rolling post-heat treatment, significantly enhancing fatigue strength by approximately 1000% compared to less rigorous methods.\n\nThis kit provides a higher clamping force essential for maintaining seal integrity, especially in high-boost scenarios. It offers enhanced resistance to head lifting, thereby ensuring greater engine durability and performance. The kit includes 10 ARP head studs, 10 ARP 12-point nuts, 10 custom-designed MAPerformance L15B7 Headstud Spacers for accurate torque application, and ARP Assembly Lube.\n\nThis is a high-performance racing component intended for dual-purpose vehicles and is not an OEM replacement. The kit is specifically designed for the 2016-2021 Honda Civic 1.5T and the 2017-2021 Honda Civic Si models equipped with the L15B7 engine.","brand":"ARP Head","offers":[{"title":"Default Title","offer_id":52686986117432,"sku":"ACR-HON-L15HSK","price":339.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687888137.webp?v=1784879210","url":"https:\/\/store.motormia.co\/products\/8740-chromoly-head-stud-kit-1","provider":"MOTORMIA","version":"1.0","type":"link"}
