In limited-slip differentials, constant high temperatures break down clutch packs and friction modifiers, resulting in reduced efficiency and compromised traction control. Built for the AAM 10.5-inch 14-bolt rear axle under 2003-2013 Ram 2500 trucks, the PPE Rear Differential Cover is cast from high-grade A356.0-T6 heat-treated aluminum alloy, adds 0.5 quart of fluid capacity, and carries half-inch external cooling fins in a brushed finish.\u003c\/p\u003e\u003cp\u003eExternal cooling fins pull heat out of the fluid and add impact resistance, while precision-placed internal windage scrapers keep fluid distributed around the gears and cut the excessive churning that causes heat, aeration, and parasitic power loss. Together the fins and scrapers form an ultra-strong cross-bracing structure, backed by cast-in gussets that support the differential housing flange. The fill plug sits at the factory level, and both service plugs carry high-temperature neodymium magnets to capture ferrous particles.\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp class=\"isSelectedEnd\"\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003ePremium A356.0-T6 heat-treated cast aluminum alloy construction\u003c\/li\u003e\n\u003cli\u003ePrecision cast in permanent steel molds for dimensional accuracy\u003c\/li\u003e\n\u003cli\u003eIncreases oil capacity by 0.5 quart for higher thermal capacity\u003c\/li\u003e\n\u003cli\u003eHalf-inch external fins lower differential fluid temperature\u003c\/li\u003e\n\u003cli\u003eInternal windage scrapers cut churning, aeration, and power loss\u003c\/li\u003e\n\u003cli\u003eFins and scrapers form an ultra-strong cross-bracing structure\u003c\/li\u003e\n\u003cli\u003eCast-in gussets add housing flange support and rigidity\u003c\/li\u003e\n\u003cli\u003e304 stainless plugs with neodymium magnets and Viton O-rings\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e \u003c\/p\u003e\u003cp class=\"isSelectedEnd\"\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eBrand: PPE\u003c\/li\u003e\n\u003cli\u003ePart Type: Rear Differential Cover\u003c\/li\u003e\n\u003cli\u003eMaterial: A356.0-T6 Heat-Treated Cast Aluminum Alloy\u003c\/li\u003e\n\u003cli\u003eFinish: Brushed\u003c\/li\u003e\n\u003cli\u003eCasting Method: Precision Cast, Permanent Steel Mold\u003c\/li\u003e\n\u003cli\u003eDifferential: AAM 10.5 in, 14-Bolt\u003c\/li\u003e\n\u003cli\u003eAdded Fluid Capacity: 0.5 Quart\u003c\/li\u003e\n\u003cli\u003eExternal Fin Height: 1\/2 in\u003c\/li\u003e\n\u003cli\u003eInternal Scrapers: Precision-Placed Windage Scrapers\u003c\/li\u003e\n\u003cli\u003eService Plugs: 304 Stainless Steel\u003c\/li\u003e\n\u003cli\u003ePlug Magnets: High-Temperature Neodymium\u003c\/li\u003e\n\u003cli\u003eOEM Reference: MOPAR 5086801AC\u003c\/li\u003e\n\u003cli\u003eWarranty: Limited Lifetime\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e \u003c\/p\u003e\u003cp class=\"isSelectedEnd\"\u003e\u003cstrong\u003eIncluded:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e(1) PPE Cast Aluminum Rear Differential Cover\u003c\/li\u003e\n\u003cli\u003e(1) 304 Stainless Steel Fill Plug with Neodymium Magnet\u003c\/li\u003e\n\u003cli\u003e(1) 304 Stainless Steel Drain Plug with Neodymium Magnet\u003c\/li\u003e\n\u003cli\u003eViton O-Rings\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e \u003c\/p\u003e\u003cp class=\"isSelectedEnd\"\u003e\u003cstrong\u003eFitment:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e2003-2009 Dodge Ram 2500 5.7L HEMI (AAM 10.5 in 14-bolt rear)\u003c\/li\u003e\n\u003cli\u003e2003-2009 Dodge Ram 2500 5.9L\/6.7L Cummins (AAM 10.5 in 14-bolt rear)\u003c\/li\u003e\n\u003cli\u003e2010-2013 Ram 2500 5.7L HEMI (AAM 10.5 in 14-bolt rear)\u003c\/li\u003e\n\u003cli\u003e2010-2013 Ram 2500 6.7L Cummins (AAM 10.5 in 14-bolt rear)\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e \u003c\/p\u003e\u003cp class=\"isSelectedEnd\"\u003e\u003cstrong\u003eNotes:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eLimited Lifetime Warranty\u003c\/li\u003e\n\u003cli\u003eWarranty does not cover modifications, alterations, or misuse\u003c\/li\u003e\n\u003cli\u003eFits the AAM 10.5-inch 14-bolt rear axle on 2003-2013 Ram 2500 trucks only - verify the axle tag before ordering\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PPE","offers":[{"title":"Default Title","offer_id":48921879019677,"sku":"238052010","price":314.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0645\/2504\/1821\/files\/2380520101.webp?v=1789658439","url":"https:\/\/rudysdiesel.com\/products\/ppe-brushed-aam-10-5in-14-bolt-rear-differential-cover-for-2003-2013-dodge-ram-2500-5-7l-hemi-6-7l-cummins","provider":"Rudy's Performance Parts","version":"1.0","type":"link"}
