{"product_id":"pro-series-head-bolt-kit","title":"Pro Series Head Bolt Kit","description":"The ARP Pro Series cylinder head bolt kit (PN 134-3610) is engineered for enhanced performance and reliability in Gen III and Gen IV LS engines, specifically those from 2004 onwards. These bolts are constructed from cold-forged material, ensuring superior molecular integrity and durability under high stress conditions. They undergo a rigorous heat-treatment process prior to thread rolling and machining, achieving a substantial tensile strength rating of 190,000 psi.\n\nIt includes hardened parallel washers that distribute load uniformly across the cylinder head surface, leading to precise torque readings and a more secure engine assembly. Available with both hex and 12-point heads, these bolts offer versatility in installation.\n\nCompatibility Note: This kit is designed for LS engines that utilize all same-length head bolts, commonly found in 2004 and later Gen III\/Gen IV LS applications. It is important to note that this kit will not fit earlier LS blocks that use two different bolt lengths. For 2000 LS1 models, the 134-3609 kit is recommended, as 2004 models saw a switch to equal-length bolts for this part number.","brand":"ARP Head","offers":[{"title":"Default Title","offer_id":52686988345656,"sku":"ARP-134-3610","price":151.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/662150772.jpg?v=1784879226","url":"https:\/\/store.motormia.co\/products\/pro-series-head-bolt-kit","provider":"MOTORMIA","version":"1.0","type":"link"}
