The third problem is the availability of replacements, this means a lot of these fasteners are not being replaced during engine rebuilds.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eThe OE B58 Girdle fasteners may be fine for OE properties, but they are not adequate for increased output. On bigger power engines we are seeing fretting transfer on the main caps, between the caps and the girdle. Our upgraded hardware helps prevent this damage by preventing movement. These fasteners are a must for big power B58 cars.\u003c\/p\u003e\n\u003cul data-mce-fragment=\"1\"\u003e\n\u003cli data-mce-fragment=\"1\"\u003eSpecifically designed to support the load and tensile requirements of increased output.\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eRequired to reach ASTM conformance certification.  All Material must conform to AMS batch raw materials.\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eThread engagement and shank is optimized for each given bolt in its specific location. \u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eMeet or exceed a minimum allowable tensile strength of 190kpsi.  \u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eCustom age hardened \u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eCorrosion resistant, there is no coating or plate film to wear or degrade.\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eReusable indefinitely unless over yielded past acceptable elongation.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp data-mce-fragment=\"1\"\u003eThis kit contains 20 bolts, use a dab of engine oil and toque to 30ft\/lb\u003c\/p\u003e","brand":"Visconti Tuning","offers":[{"title":"Default Title","offer_id":46265818480836,"sku":"VIS VB58F0102","price":600.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0748\/6216\/6212\/files\/GirdleBolts_540x_a0cefe8f-43bf-4bd0-b099-9d3e4c0e066e.jpg?v=1781684890","url":"https:\/\/wktuning.com\/products\/visconti-upgraded-b58-girdle-and-oil-pump-bolts","provider":"WK Performance","version":"1.0","type":"link"}
