{"product_id":"arp-professional-series-cylinder-head-stud-kit-for-toyota","title":"ARP Professional Series Cylinder Head Stud Kit for Toyota","description":"The ARP 203-4206 is a professional series cylinder head stud kit engineered for Toyota 1.6L (2TC) and 1.8L (3TC) engines. This kit ensures enhanced sealing and durability for high-performance applications. ARP Pro Series head studs are favored by professional engine builders for their robust construction and reliability.\n\nConstructed from premium grade 8740 alloy (rated to 200,000 psi), these studs are heat-treated to ensure complete penetration and superior strength. The manufacturing process includes centerless grinding for exceptional straightness and concentricity, allowing gaskets and cylinder heads to glide into place with perfect alignment. Furthermore, ARP studs are thread rolled after heat-treat, a process that significantly increases fatigue strength by approximately 2000% compared to studs threaded before heat-treating.\n\nThis kit features a durable black oxide finish and includes 12-point nuts for secure tightening. The meticulous manufacturing tolerances and quality materials contribute to a more consistent clamping force, which helps prevent head gasket failure and ensures optimal engine sealing. ARP studs are stamped with their logo as an assurance of quality, making them a trusted choice for serious engine builders in all forms of racing.\n\nThese head studs are designed for specific Toyota engines, namely the 1.6L (2TC) and 1.8L (3TC) variants. The product is sold as a kit and is not vehicle-specific in its general listing, meaning customers are responsible for confirming fitment for their particular application.","brand":"ARP Head","offers":[{"title":"Default Title","offer_id":52686988083512,"sku":"203-4206","price":168.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687888287.jpg?v=1784879224","url":"https:\/\/store.motormia.co\/products\/arp-professional-series-cylinder-head-stud-kit-for-toyota","provider":"MOTORMIA","version":"1.0","type":"link"}
