That focus on fastener integrity still drives the company today: ARP studs and bolts are precision heat treated, centerless ground for concentricity, and thread rolled after heat treat for maximum fatigue strength, all manufactured in the USA.\u003c\/p\u003e","brand":"ARP","offers":[{"title":"Default Title","offer_id":51978905747777,"sku":"ARP203-6001","price":63.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0835\/9362\/5921\/files\/arp-m9-rod-bolt-kit-for-85-89-toyota-mr2-4a-ge-2519966.jpg?v=1784507710","url":"https:\/\/lunaticsco.com\/products\/arp-toyota-4age-m9-rod-bolt-kit","provider":"Lunaticsco","version":"1.0","type":"link"}
