It replaces factory numbers such as 12589016, BTR89016, 83470, 61220G and cross-references B31822, making it suitable for popular engine codes including LS1, LS2, LS3, LSX, L83, L86, L87, L84, LT4, LQ4, and LQ9. The components are designed to seal the retainer plate, limit camshaft axial movement, and resist contamination, delivering improved durability and service life compared with worn or brittle OE parts.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this retainer plate gasket restore engine sealing?\u003c\/h3\u003e\n\u003cp\u003eThe gasket is precision-molded to match the OEM retainer plate profile and mounting holes so it seats reliably under the plate. Proper sealing helps prevent oil leakage and keeps debris out of the timing assembly area, which preserves camshaft geometry and timing performance.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eExact fit to common GM LS\/LT retainer plate dimensions\u003c\/li\u003e\n  \u003cli\u003eMaterial chosen for oil resistance and temperature stability\u003c\/li\u003e\n  \u003cli\u003eIncludes gasket and hardware for one complete retainer plate installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhy include the ARP 134-1003 camshaft thrust bolt kit?\u003c\/h3\u003e\n\u003cp\u003eARP fasteners are made from high-strength alloy and are engineered to withstand repeated torque cycles and engine stresses.

It’s especially useful when replacing a camshaft, repairing front timing components, addressing oil leaks around the retainer plate, or upgrading to more durable fasteners in higher-stress applications. While it’s designed to match OE fitment, confirm engine code and part number compatibility before installation to ensure a correct match for your vehicle.\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 kit fit my LS3 or LT4 engine?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes — the gasket and ARP bolts are compatible with many LS3 and LT4 variants; confirm your engine code and OE part number before ordering.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Should I replace the thrust bolt when changing the retainer gasket?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes — replacing the cam thrust bolt with the ARP kit ensures proper clamping and reduces risk of fastener fatigue.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"koxuyim","offers":[{"title":"Default Title","offer_id":55164034810199,"sku":"B09G2SHNTT","price":32.43,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1050\/1524\/7191\/files\/koxuyim-retainer-plate-gasket-front-view.jpg?v=1790349085","url":"https:\/\/britishgarage.co.uk\/products\/koxuyim-camshaft-retainer-plate-gasket-arp-thrust-bolt-kit-fit-for-gm-ls-lt-engines-direct-fit-seal","provider":"British Garage","version":"1.0","type":"link"}
