This ARP exhaust manifold bolt kit is built to solve that problem with strength you can count on, especially when your truck is working hard or making more power than stock. Right away, you get a more secure hold that helps keep the manifold tight against the head, even as temperatures climb and drop during daily driving. Additionally, this added clamping force goes a long way in preventing leaks that tend to show up over time with factory bolts. The hex head design also makes installation straightforward, which is always a win when you are working in tight engine bay spaces. What’s more, the durability of these fasteners means you are not revisiting the same repair down the road. It is the kind of upgrade that makes sense whether you are maintaining a work truck or building something with more performance in mind. Once installed, you can focus on driving instead of chasing exhaust issues.\u003c\/p\u003e\n\u003ch4\u003eEngineered Fastener Strength Built For Extreme Cummins Exhaust Conditions\u003c\/h4\u003e\n\u003cp\u003eThe ARP 447-1101 exhaust manifold bolt kit is designed for 2003-2025 Dodge Ram Cummins 5.9L and 6.7L engines, providing a durable solution for high heat applications. Each fastener is manufactured from premium 8740 chromoly steel, delivering excellent tensile strength and resistance to fatigue under repeated thermal cycling. Furthermore, the black oxide coating adds corrosion resistance, helping the hardware maintain integrity in harsh exhaust environments. The hex head design allows for easy installation with standard tools, while also improving engagement in confined areas around the manifold. Proper clamping force is critical in preventing manifold movement, which can lead to gasket failure or warping over time. Additionally, this kit is designed to maintain consistent sealing pressure, supporting long term reliability in both stock and performance setups. It is important to note that the OEM heat shield is not compatible with this kit due to the hardware design. Altogether, this setup delivers a well engineered fastening solution built to handle the demands of Cummins exhaust systems.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e Fitment: \u003c\/strong\u003e 2003, 2004, 2005, 2006, 2007, 2008, 2009, 2010, 2011, 2012, 2013, 2014, 2015, 2016, 2017, 2018, 2019, 2020, 2021, 2022, 2023, 2024, 2025 Dodge RAM 2500\/3500 5.9\/6.7L Cummins No Spacers\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNotes:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eFits 2003-2025 Cummins 5.9L and 6.7L engines\u003c\/li\u003e\n\u003cli\u003eOEM heat shield cannot be reused\u003c\/li\u003e\n\u003cli\u003eDesigned for exhaust manifold applications only\u003c\/li\u003e\n\u003cli\u003eFollow ARP torque specifications during install\u003c\/li\u003e\n\u003cli\u003eARP lubricant recommended for accurate torque\u003c\/li\u003e\n\u003cli\u003eEnsure mating surfaces are clean and flat\u003c\/li\u003e\n\u003cli\u003eCheck manifold for warping before install\u003c\/li\u003e\n\u003cli\u003eIdeal for high heat and performance applications\u003c\/li\u003e\n\u003cli\u003eNot a direct reuse of factory hardware specs\u003c\/li\u003e\n\u003cli\u003eProfessional installation recommended for best results\u003c\/li\u003e\n\u003cli\u003eVerify proper tightening sequence during install\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ARP","offers":[{"title":"Default Title","offer_id":54046016143644,"sku":"ARP447-1101","price":74.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0738\/2279\/8108\/files\/arp-447-1101_xl.jpg?v=1776366241","url":"https:\/\/www.alligatorperformance.com\/products\/arp-447-1101","provider":"Alligator Performance","version":"1.0","type":"link"}
