In limited-slip differentials, constant high temperatures can break down clutch packs and friction modifiers, resulting in reduced efficiency and compromised traction control. Cast from high-grade A356.0-T6 aluminum alloy, the PPE differential cover adds 0.57 quarts of fluid capacity and features half-inch external cooling fins for long-lasting heat management and performance. Built-in windage scrapers inside the PPE cover ensure precise fluid distribution around the gears. By reducing excessive fluid churning, these scrapers lower heat buildup and minimize parasitic loss, promoting more efficient power transfer. Together with the vertical external fins, they form a strong cross-bracing structure that improves load distribution and enhances impact resistance. The fill plug is precisely positioned at the factory level. Both the fill and drain plugs feature a powerful, high-temperature-rated neodymium magnet that captures ferrous particles for added protection.\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"color: rgb(255, 42, 0);\"\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003ePremium A356.0-T6 heat-treated cast aluminum alloy – a high-strength, thermally conductive material\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003ePrecision-cast using permanent steel molds for a smooth, consistent finish and high dimensional accuracy\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eIncreases oil capacity by 0.57 quarts for higher thermal capacity\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eHalf-inch external fins improve heat dissipation, lower differential fluid temperature, and increase impact resistance\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003ePrecision-placed internal windage scrapers prevent excessive churning, reducing heat generation, fluid aeration, and power loss\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eExternal fins and internal scrapers work together to form an ultra-strong Cross-Bracing structure\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eCast-in gussets for additional differential housing flange support and increased rigidity\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e304 Stainless steel service plugs with high-strength, high-temperature-rated neodymium magnets and Viton O-rings\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cspan style=\"color: rgb(255, 42, 0);\"\u003e\u003cstrong\u003eNotes:\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eThe differential cover is designed to fit SU8 rear axles only.\u003c\/li\u003e\n\u003cli\u003eNot compatible with AAM 9.5\" rear axles with build code SU7\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003ePlease give our sales team a call with your VIN to confirm fitment\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PPE","offers":[{"title":"Raw","offer_id":49746844680330,"sku":"138051400","price":251.99,"currency_code":"USD","in_stock":true},{"title":"Brushed","offer_id":49746844713098,"sku":"138051410","price":269.99,"currency_code":"USD","in_stock":true},{"title":"Black","offer_id":49746844745866,"sku":"138051420","price":269.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0354\/0887\/1562\/files\/138051400.png?v=1784219598","url":"https:\/\/dmaxstore.com\/products\/ppe-9-5-12-bolt-heavy-duty-cast-aluminum-rear-differential-cover-2020-2026-lm2-lz0","provider":"DmaxStore","version":"1.0","type":"link"}
