It’s designed for street builds, performance upgrades, and engine rebuilds on LS1, LS2, LS3, LSX and many LT-series platforms, delivering reliable sealing around the cam retainer and secure camshaft thrust fastening that resist leaks and movement under load.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this kit restore camshaft sealing and prevent leaks?\u003c\/h3\u003e\n\u003cp\u003eThe koxuyim gasket is die-cut to the same profile as the factory retainer plate gasket, providing consistent compression and sealing surfaces to keep oil within the cam gallery. Proper sealing reduces the chance of oil weeping around the retainer and into accessory areas, maintaining correct oil flow and cleanliness in the valvetrain area.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eExact-fit gasket shape for GM Gen 3–5 LS and LT engines.\u003c\/li\u003e\n  \u003cli\u003eDurable material selected for oil and heat resistance.\u003c\/li\u003e\n  \u003cli\u003ePrevents external oil seepage from the cam retainer area.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat makes the included cam thrust bolts suitable for performance engines?\u003c\/h3\u003e\n\u003cp\u003eThe bolt kit mirrors the ARP 134-1003 High Performance Series specifications used across many LS and LT builds, supplying high tensile strength and consistent clamping force for camshaft thrust control. Stronger bolts reduce stretch and loosening risk during high-RPM or modified engine operation, keeping camshaft endplay within design limits.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eHigh-strength construction for consistent clamping and durability.\u003c\/li\u003e\n  \u003cli\u003eCompatibility with LSX, LS1, LT1, L83, L86, L87, L84, LT4, LQ4, LQ9, LS2, LS3 platforms.\u003c\/li\u003e\n  \u003cli\u003eLowers chance of bolt failure or camshaft movement under stress.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eIs this a direct replacement for the factory part numbers and cross-references?\u003c\/h3\u003e\n\u003cp\u003eYes — the kit is manufactured to match the form and function of common GM retainer plate part numbers (12589016 and listed alternates) and interchange B31822, making it suitable as a like-for-like replacement during rebuilds or repairs. That interchangeability simplifies parts sourcing and ensures the retainer plate mates correctly with OEM housings.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eReplaces GM part numbers: 12589016, BTR89016, 83470, 61220G.\u003c\/li\u003e\n  \u003cli\u003eInterchange: B31822 for broader compatibility.\u003c\/li\u003e\n  \u003cli\u003eDesigned for drop-in fit during routine camshaft service or rebuild.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow should I install the gasket and bolts to get reliable results?\u003c\/h3\u003e\n\u003cp\u003eInstall the gasket on a clean, oil-free retainer face and use the thrust bolts torqued to the manufacturer or ARP-specified values. Clean mating surfaces, inspect for warpage or damage, and follow torque sequence to ensure even clamping and sealing performance.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eClean and degrease mating surfaces before installation.\u003c\/li\u003e\n  \u003cli\u003eUse proper torque specs and sequence; consider thread lubricant if specified.\u003c\/li\u003e\n  \u003cli\u003eInspect retainer plate and cam for wear before final assembly.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho is this for? Mechanics, engine builders, and DIY enthusiasts working on GM LS or LT engines who need a dependable, cost-effective replacement for the camshaft retainer plate gasket and a high-quality cam thrust bolt set. It’s appropriate for everyday drivers, performance projects, and full engine rebuilds where correct sealing and cam control are required without custom modification.\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: Will this fit my LS3 or LS2 engine?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes.
