aFe POWER Pro Series Rear Differential Cover Black w/Machined Fins - #46-71150B - RAM Trucks 19-25 L6/V8 (AAM 11.5/11.8/12.0-14)

The aFe POWER Differential Cover or "Diff Cover" in short, seals the differential and helps protect the gears, bearings, and fluid inside. It helps keep the oil inside and contaminants out. While the stock covers are good for normal use, our covers are made from cast aluminum and iron, with cooling fins, reinforced ribs, or drain/fill plugs for better performance and ease of maintenance.

• Increased oil capacity over stock for better performance over a longer duration
• Neodymium magnetic drain plug is used for maximum gear protection
• Built-in internal and external fins transfer heat from the oil to the outside air for maximum cooling
• Calibration Plug Prevents Overfilling
