9.75-12" Heavy-Duty Cast Aluminum Rear Differential Cover | 09-21+ F150

FEATURES

• Premium A356.0-T6 heat-treated cast aluminum alloy – a high-strength, thermally conductive material
• Precision-cast using permanent steel molds for a smooth, consistent finish and high dimensional accuracy
• Increases oil capacity by 0.43 quart for higher thermal capacity
• Half-inch external fins improve heat dissipation, lower differential fluid temperature, and increase impact resistance
• Precision-placed internal windage scrapers prevent excessive churning, reducing heat generation, fluid aeration, and power loss
• External fins and internal scrapers work together to form an ultra-strong Cross-Bracing structure
• Cast-in gussets for additional differential housing flange support and increased rigidity
• 304 Stainless steel service plugs with built-in high temperature rated neodymium magnets and Viton O-rings

PPE’s differential covers offer industry-leading fluid cooling. Keep your Ford rear differential running cool and clean with an upgraded cover from PPE. Made from high-quality cast aluminum for strength and optimum heat dissipation.

Increased fluid capacity provides increased thermal stamina. This new cover is equipped with internal heat sinks and external cooling fins which increase the pan’s surface area helping dissipate heat. This keeps your differential oil running cooler, the oil will keep its viscosity, helping extend differential service life. 

To help keep fluid cleaner, PPE includes our exclusive fill plug featuring a high-powered Neodymium magnet that will pull harmful ferrous metal particles right out of your oil before they have a chance to do damage.
