Under repeated high-load use, particularly on fast-road or track-driven vehicles, these fasteners can become a reliability concern.\u003c\/p\u003e\n\u003cp data-end=\"1049\" data-start=\"767\"\u003eXC3 upgraded bolts move to a 12.9 tensile specification, providing a clear strength increase over the factory hardware. The higher tensile rating offers improved resistance to bolt stretch and fatigue, resulting in greater clamping force retention at critical drivetrain joints.\u003c\/p\u003e\n\u003cp data-end=\"1202\" data-start=\"1051\"\u003eThis upgrade provides a stronger, more robust fastening solution for owners seeking improved durability and confidence in demanding driving conditions.\u003c\/p\u003e\n\u003cp data-end=\"1202\" data-start=\"1051\"\u003eReplaces BMW part no. \u003cmeta charset=\"utf-8\"\u003e26117526322\u003c\/p\u003e\n\u003cp\u003eKit Details and Contents:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e6x Cap Head Screw Bolts\u003c\/li\u003e\n\u003cli\u003e12.9 Tensile strength \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eFitment:\u003c\/p\u003e\n\u003cp\u003eBMW M3 E9X Chassis\u003c\/p\u003e","brand":"XC3 Engineering","offers":[{"title":"Default Title","offer_id":52889522045195,"sku":"XC3-PSB-001","price":29.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0744\/8484\/2763\/files\/BMWE9XUPB1.jpg?v=1770716201","url":"https:\/\/www.xc3.co.uk\/products\/xc3-engineering-bmw-m3-e9x-e92-upgraded-propshaft-driveshaft-bolts","provider":"XC3 Engineering","version":"1.0","type":"link"}
