1994-2024 Diesel HD Heavy-Duty Cast Aluminum Rear Differential Cover Raw Silver (238051000)

Description

Made in the USA from high-quality cast aluminum for strength and optimum heat dissipation. PPEs differential covers offer industry-leading fluid cooling. Equipped with internal heat sinks and external cooling fins, increasing the pans surface area helping dissipate heat. This makes for a much cooler and denser oil. Cool, dense fluid lubricates better, which will extend differential service life.

To keep the fluid clean, PPE installed its exclusive high-powered Neodymium magnet equipped fill plug will pull harmful ferrous metal particles right out of the oil before they have a chance to attack the bearings and gears.

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 .63 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

Notes

• Only works with vehicles equipped with AAM 11.5"-14 axles.
• Not compatible with certain 2003-2012 Dodge Ram HD trucks equipped with Anti-Spin Differential rear axles due to the tone ring sensor; for these applications see the 2001-2019 GM, 2001-2018 RAM AAM 11.5"-14-Bolt Heavy-Duty Cast Aluminum Rear Differential Cover (P/N 138051000).
