PPE HD Cast Aluminum Rear Diff Cover 9.25"-12-Bolt: Dodge Ram 1500 1994 - 2026

PPE Rear Differential Cover1994–2024 Dodge Ram 1500 9.25"-12-Bolt 238051320 Overview: The PPE Rear Differential Cover is a heavy-duty upgrade designed specifically for Dodge Ram 1500 models equipped with the 9.25" 12-bolt rear differential from 1994 through 2024. Crafted to enhance durability and thermal management, this cast aluminum cover protects your differential while improving fluid capacity and heat dissipation. It is ideal for truck owners who demand reliable performance under heavy loads, towing, or off-road conditions where excessive heat buildup can compromise differential components and traction control. By addressing the common issue of heat degradation in differential fluid, the PPE cover helps extend the life of gears, bearings, and limited-slip clutch packs. This ensures consistent power transfer and better traction, making it a smart investment for enthusiasts and professionals alike. Key Features: This rear differential cover incorporates advanced engineering features to optimize performance and protection: Constructed from high-grade A356.0-T6 cast aluminum for superior strength and corrosion resistance Increases fluid capacity by 0.5 quarts, improving lubrication and cooling Half-inch external cooling fins enhance heat dissipation to maintain optimal operating temperatures Internal windage scrapers reduce fluid churning, lowering heat buildup and parasitic power loss Strong cross-bracing structure formed by vertical external fins improves load distribution and impact resistance Factory-level positioned fill plug for easy and accurate fluid maintenance High-temperature-rated neodymium magnets in both fill and drain plugs capture ferrous particles to protect internal components Construction & Design: The PPE differential cover is precision cast from premium A356.0-T6 aluminum alloy, known for its excellent strength-to-weight ratio and thermal conductivity. This material choice ensures the cover can withstand harsh operating conditions while effectively dissipating heat generated by the differential during heavy use. The design incorporates half-inch external cooling fins that increase surface area for improved heat transfer. Internally, windage scrapers are engineered to direct fluid flow precisely around the gears, minimizing turbulence and reducing heat generation. The vertical fins also act as a robust cross-bracing system, enhancing structural rigidity and protecting the differential housing from impacts and deformation. Installation & Fitment: The PPE Rear Differential Cover is a direct bolt-on replacement for Dodge Ram 1500 trucks equipped with the 9.25" 12-bolt rear differential from model years 1994 through 2024. Installation requires no modifications, making it a straightforward upgrade for DIY enthusiasts or professional mechanics. The cover includes factory-positioned fill and drain plugs to simplify fluid servicing and maintenance. What's Included: Heavy-duty cast aluminum rear differential cover Fill plug with high-temperature neodymium magnet Drain plug with high-temperature neodymium magnet Installation hardware Detailed installation instructions Ideal For: This differential cover is perfect for Dodge Ram 1500 owners who frequently tow, haul heavy loads, or drive off-road and require enhanced differential protection and cooling. It benefits those looking to extend the life of their differential components, improve traction control reliability, and reduce maintenance intervals caused by heat-related fluid degradation.
