Over time, high thermal cycles and continuous yoke rotation break down the outer rubber sealing lip, resulting in gear oil leaking onto your undercarriage. When servicing this seal, reusing a stretched or deformed pinion nut is a major liability that can cause the pinion to back off—altering gear mesh and inviting catastrophic differential failure. This premium service bundle removes the risk by replacing worn hardware with trusted Spicer OEM parts, ensuring precise thread engagement, exact torque retention, and factory-fresh fluid sealing.\u003c\/p\u003e\n\u003cp data-path-to-node=\"8\"\u003e\u003cb data-path-to-node=\"8\" data-index-in-node=\"0\"\u003eKit Highlights:\u003c\/b\u003e\u003c\/p\u003e\n\u003cul data-path-to-node=\"9\"\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"9,0,0\"\u003e\u003cb data-path-to-node=\"9,0,0\" data-index-in-node=\"0\"\u003ePremium Dual-Component Bundle:\u003c\/b\u003e Includes one genuine rubber-lipped pinion oil seal and one heavy-duty self-locking pinion yoke nut.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"9,1,0\"\u003e\u003cb data-path-to-node=\"9,1,0\" data-index-in-node=\"0\"\u003eGenuine Spicer OEM Quality:\u003c\/b\u003e Precision-machined to rigid original equipment specifications, using high-performance, oil-resistant elastomers to withstand aggressive gear oil additives and friction.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"9,2,0\"\u003e\u003cb data-path-to-node=\"9,2,0\" data-index-in-node=\"0\"\u003eMaintains Preload Integrity:\u003c\/b\u003e The included heavy-duty self-locking nut ensures that your internal pinion bearing preload remains securely clamped under severe structural loading.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"9,3,0\"\u003e\u003cb data-path-to-node=\"9,3,0\" data-index-in-node=\"0\"\u003eDirect Multi-Platform Fit:\u003c\/b\u003e Mapped as a direct factory replacement for heavy-duty Dana 80 rear axle configurations across major truck manufacturers.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp data-path-to-node=\"10\"\u003e\u003cb data-path-to-node=\"10\" data-index-in-node=\"0\"\u003eVehicle \u0026amp; Axle Fitment:\u003c\/b\u003e\u003c\/p\u003e\n\u003cul data-path-to-node=\"11\"\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"11,0,0\"\u003e\u003cb data-path-to-node=\"11,0,0\" data-index-in-node=\"0\"\u003eMakes:\u003c\/b\u003e Ford \/ Dodge Ram \/ Chevrolet \/ GMC\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"11,1,0\"\u003e\u003cb data-path-to-node=\"11,1,0\" data-index-in-node=\"0\"\u003eCommon Applications:\u003c\/b\u003e F-350 Dually, F-450, Ram 2500\/3500 (with Cummins\/V10 \u0026amp; Manual Trans), Silverado\/Sierra 3500 HD\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"11,2,0\"\u003e\u003cb data-path-to-node=\"11,2,0\" data-index-in-node=\"0\"\u003eAxle Profile:\u003c\/b\u003e Dana 80 Rear Axle Assemblies Only\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"11,3,0\"\u003e\u003cb data-path-to-node=\"11,3,0\" data-index-in-node=\"0\"\u003ePosition:\u003c\/b\u003e Rear Differential Input \/ Pinion Yoke Center Axis\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Spicer","offers":[{"title":"Default Title","offer_id":43563541299274,"sku":"PLAT-SPICER-KIT174","price":44.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0706\/5560\/6858\/files\/10_2debd8f4-1b5c-468a-9a50-6749af320c57.jpg?v=1777818422","url":"https:\/\/platinumperformanceparts.com\/products\/dana-80-pinion-seal-nut-ford-dodge-chevy-dana-80-rear-axle","provider":"Platinum Performance Parts","version":"1.0","type":"link"}
