Constructed from premium A356.0-T6 heat-treated cast aluminum, this upgraded cover is engineered to help manage differential temperatures, increase fluid capacity, and provide added strength for towing, hauling, and performance applications.\u003c\/p\u003e\n\n\u003cp\u003eThe precision-cast design features external cooling fins that help dissipate heat, while internal windage scrapers help control fluid movement around the gears. By reducing excessive fluid churning and aeration, the scrapers help minimize heat buildup and parasitic power loss. Together, the internal scrapers and external fins create a reinforced cross-bracing structure for improved rigidity and impact resistance.\u003c\/p\u003e\n\n\u003cp\u003eThis PPE differential cover increases fluid capacity by approximately 0.63 quart, providing additional thermal capacity for demanding driving conditions. Cast-in gussets reinforce the differential housing flange, while stainless steel service plugs feature high-temperature neodymium magnets to capture ferrous metal particles from the differential fluid. Viton O-rings help provide a secure seal at the service plugs.\u003c\/p\u003e\n\n\u003cp\u003eDesigned as a heavy-duty upgrade for compatible GM and Ram trucks, the PPE Cast Aluminum Rear Differential Cover combines improved heat management with durable construction to help protect critical drivetrain components over the long haul.\u003c\/p\u003e\n","brand":"PPE (Pacific Performance Eng.)","offers":[{"title":"Raw","offer_id":67880079065453,"sku":"PPE-238051100","price":287.99,"currency_code":"USD","in_stock":true},{"title":"Brushed","offer_id":67880079098221,"sku":"PPE-238051110","price":305.99,"currency_code":"USD","in_stock":true},{"title":"Black","offer_id":67880079130989,"sku":"PPE-238051120","price":305.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0892\/2487\/2301\/files\/PACIFICPERFORMANCEENGINEERING_PACIFICPERFORMANCEENGINEERING_9_3e3d8f1b-4b04-482d-83f1-3ae9a487d7f9.jpg?v=1793640559","url":"https:\/\/dieselpowerproducts.com\/products\/ppe-heavy-duty-cast-aluminum-rear-differential-cover-aam-11-5-14-bolt-01-19-gm-2500hd-3500-01-18-ram-2500-3500","provider":"Diesel Power Products","version":"1.0","type":"link"}
