They fit many GM LS-family engines and are precision-machined to tight tolerances so the valvetrain maintains consistent operation whether used in daily drivers, performance street cars, or race applications.\u003c\/p\u003e\n\n\u003ch3\u003eWhich LS engines will these 7.400\" pushrods fit?\u003c\/h3\u003e\n\u003cp\u003eThese pushrods are specified at a stock length of 7.400\" and a 5\/16\" diameter, matching the factory sizing used across numerous LS-series V8s.

The result is a more rigid link between lifter and rocker, which helps maintain accurate valve motion at higher RPM and under heavy spring pressure.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e4130 chromoly construction for superior rigidity and fatigue resistance\u003c\/li\u003e\n  \u003cli\u003ePrecision-machined ends to ensure consistent seating and alignment\u003c\/li\u003e\n  \u003cli\u003eTight manufacturing tolerances for predictable valvetrain geometry\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eAre these pushrods suitable for performance builds or only stock replacements?\u003c\/h3\u003e\n\u003cp\u003eThey are designed to serve both roles. For stock-replacement needs they restore original valvetrain geometry and durability; for mild to moderate performance upgrades they provide extra strength where factory pushrods may flex. For extreme high-lift or competition-level builds, check spring pressures and valvetrain specs to confirm compatibility.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eIdeal for street performance, weekend track use, and towing\/heavy-duty applications\u003c\/li\u003e\n  \u003cli\u003eWorks with OEM and many aftermarket rocker\/lifter combinations (confirm clearance)\u003c\/li\u003e\n  \u003cli\u003eNot a substitute for specialized pushrods specified by race engine builders when extreme spring pressures or length modifications are required\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat installation and verification steps should I follow?\u003c\/h3\u003e\n\u003cp\u003eInstallation follows standard pushrod replacement practice: confirm engine is at TDC on compression for the cylinder being adjusted, swap pushrods one at a time to retain lifter oiling, and verify valve lash or hydraulic preload per the cam and lifter type. After installation, run the engine and recheck clearances.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eReplace one pushrod at a time to keep lifters properly oiled\u003c\/li\u003e\n  \u003cli\u003eVerify pushrod length, valve lash, and lifter preload per engine specs\u003c\/li\u003e\n  \u003cli\u003ePerform a post-installation recheck after initial run-in\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho this is for: The Michigan Motorsports 7.400\" chromoly pushrods suit car owners, mechanics, and builders who need a strong, accurately made pushrod for GM LS engines. Choose these when you want a durable OEM-length replacement that resists flex under higher RPM and provides reliable valvetrain performance for street, sport, or light competition use. If your project demands custom lengths or extreme competition valvetrain components, consult a builder or measure your valvetrain geometry before ordering.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Do these pushrods require any modification to fit LS engines?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: No modifications are typically needed for supported LS models; they are stock-length 7.400\" 5\/16\" pushrods designed for direct fitment.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Are these pushrods suitable for high-RPM performance engines?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes, 4130 chromoly construction increases rigidity for higher RPM use, though verify spring pressures for extreme competition builds.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"Michigan Motorsports","offers":[{"title":"Default Title","offer_id":48081505288350,"sku":"B083C216MH","price":174.48,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0781\/2041\/9486\/files\/michigan-motorsports-front-packaging_3443d49e-e6fe-4389-95a7-d1506247bbe1.jpg?v=1785806919","url":"https:\/\/northtrailauto.ca\/products\/michigan-motorsports-7-400-chromoly-ls-pushrods-stock-length-5-16-4130-steel-oem-fit-durability","provider":"North Trail Auto","version":"1.0","type":"link"}
