This ARP thermostat housing bolt kit is one of those upgrades that instantly gives you more confidence every time you button things up. Right away, you get better clamping force than factory hardware, which helps keep the thermostat housing sealed tight and free from annoying coolant leaks. Additionally, the 12 point head design makes installation smoother, especially when you are dealing with tight spaces around the front of the engine. It is a simple swap, but one that adds long term value whether you are refreshing your cooling system or doing a deeper engine service. What’s more, the corrosion resistant construction holds up against heat and coolant exposure, so you are not dealing with rusted or worn bolts down the road. This is the kind of upgrade that keeps your engine bay looking clean while also improving reliability. Once installed, it is one less thing you have to worry about every time you pop the hood.\u003c\/p\u003e\n\u003ch4\u003ePrecision Fastener Design Built For Duramax Cooling System Reliability\u003c\/h4\u003e\n\u003cp\u003eThe ARP 130-7403 thermostat housing bolt kit is engineered for GM 6.6L Duramax engines from LB7 through LBZ, ensuring proper fitment and consistent performance. Each fastener is manufactured using high quality stainless steel, which provides excellent resistance to corrosion in coolant exposed environments. Furthermore, the threads are precision formed to deliver accurate torque readings, helping achieve proper preload during installation. This is critical for maintaining even clamping force across the thermostat housing, which directly impacts gasket sealing and long term durability. The 12 point head design allows for improved tool engagement, reducing the risk of rounding while also making access easier in confined areas. Additionally, the bolts are designed to be reusable, making them a dependable choice for future maintenance or upgrades. This kit is ideal for both stock applications and modified builds where reliability is a priority. Altogether, it delivers a well engineered fastening solution that supports consistent cooling system performance.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFitment: \u003c\/strong\u003e\u003cspan class=\"TextRun SCXW154874320 BCX0\" lang=\"EN-US\" data-contrast=\"auto\"\u003e\u003cspan class=\"NormalTextRun SCXW154874320 BCX0\"\u003e2001, 2002, 2003, 2004, 2005, 2006, \u003c\/span\u003e\u003c\/span\u003e2007 GM Sierra\/Silverado 2500HD\/3500HD 6.6L Duramax LB7\/LBZ\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNotes:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eFits Duramax LB7 through LBZ engines only\u003c\/li\u003e\n\u003cli\u003eDesigned specifically for thermostat housing use\u003c\/li\u003e\n\u003cli\u003eARP thread lubricant recommended for installation\u003c\/li\u003e\n\u003cli\u003eFollow ARP torque specs for proper sealing\u003c\/li\u003e\n\u003cli\u003eNot intended for other engine applications\u003c\/li\u003e\n\u003cli\u003eEnsure mating surfaces are clean and flat\u003c\/li\u003e\n\u003cli\u003eInspect gasket or seal before reinstalling\u003c\/li\u003e\n\u003cli\u003eProper torque sequence helps prevent leaks\u003c\/li\u003e\n\u003cli\u003eIdeal for cooling system service or upgrades\u003c\/li\u003e\n\u003cli\u003eCompatible with stock and aftermarket housings\u003c\/li\u003e\n\u003cli\u003eAllow engine to cool before installation\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ARP","offers":[{"title":"Default Title","offer_id":54045887987996,"sku":"ARP130-7403","price":17.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0738\/2279\/8108\/files\/71ejOr_kNiL._AC_UL495_SR435_495.jpg?v=1776357758","url":"https:\/\/www.alligatorperformance.com\/products\/arp-arp130-7403","provider":"Alligator Performance","version":"1.0","type":"link"}
