{"product_id":"8740-chromoly-steel-connecting-rod-bolt-kit","title":"8740 Chromoly Steel Connecting Rod Bolt Kit","description":"The ARP EJ20\/EJ25 Main Bolt Kit is a high-performance replacement for factory fasteners, engineered to meet the demanding standards of professional engine builders.\n\nThe design incorporates a reduced wrenching head, a large underhead radius, and rolled threads. The threads are rolled after heat-treating, providing approximately 2,000 percent better fatigue strength compared to bolts threaded before heat treatment. This meticulous process ensures utmost reliability under extreme conditions. Hardened, parallel-ground washers are included with each kit for a complete and robust installation.\n\nThis main bolt kit is designed for Subaru EJ20 and EJ25 engines. Applicable vehicles include various Subaru Legacy, Impreza WRX, WRX STI, and Baja Turbo models, as well as the Saab 9-2X Aero. The kit is intended as a direct replacement for OEM fasteners, offering a significant upgrade in strength and durability for performance-oriented builds.","brand":"ARP","offers":[{"title":"Default Title","offer_id":52686984151352,"sku":"ARP-260-5401","price":414.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/660676773.jpg?v=1784879196","url":"https:\/\/store.motormia.co\/products\/8740-chromoly-steel-connecting-rod-bolt-kit","provider":"MOTORMIA","version":"1.0","type":"link"}
