ARP’s 200-2902 Pro Series flexplate bolt set is aimed at mechanics, engine builders, restorers, and performance enthusiasts who require a higher-strength replacement for stock flexplate hardware. It’s suitable for rebuilds, engine swaps, and high-use or high-vibration applications where reliable clamp and engineered fastener performance matter. Because these bolts are made in the USA and produced from chromoly with a black oxide finish, they offer a balance of durability and corrosion resistance for long-term service. Before purchase, confirm thread size and length match your crank and flexplate specifications; if uncertain, consult the vehicle service manual or ARP’s technical resources to prevent misfit or improper torque application.\u003c\/p\u003e\n\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Are these ARP bolts reusable after removal?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: ARP chromoly bolts can be reused if undamaged, but inspect threads and length; replacement is recommended if stretched or thread-worn.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Do I need special lubricant or torque specs for these bolts?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes—use ARP-specified lubricant and torque values for chromoly fasteners to ensure correct preload and avoid bolt failure.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"ARP","offers":[{"title":"Default Title","offer_id":48084647477406,"sku":"B000CFQ4A8","price":36.48,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0781\/2041\/9486\/files\/arp-flexplate-bolt-kit-front-label.jpg?v=1785861655","url":"https:\/\/northtrailauto.ca\/products\/arp-flexplate-bolt-kit-7-16-20-x-0-680-in-pro-series-chromoly-12-point-head-black-oxide-set-of-6","provider":"North Trail Auto","version":"1.0","type":"link"}
