Enhance Differential Protection and Performance. This AFE Pro Series Rear Differential Cover is designed to deliver better protection, cooling, and serviceability to your vehicle’s rear differential. It holds additional fluid compared to stock covers, helping reduce operating temperatures during towing, off-roading, or prolonged high-speed use. The integrated sight glass and magnetic drain plug simplify fluid checks and maintenance, making it a perfect upgrade for performance and utility-focused builds.
High-Strength Build for Long-Term Durability. Constructed from durable die-cast aluminum and coated with a black textured finish, this differential cover resists both corrosion and impact damage. Machined fins on the outer surface help dissipate heat, while the large oil cavity supports extended use and protection under load. It’s made to handle extreme conditions while maintaining fluid integrity and component reliability.
Installation. This product installs by removing the factory cover and sealing the new unit in place with RTV and included stainless hardware. The fluid refill is required after installation.
Application. This AFE Pro Series Rear Differential Cover fits 2003–2018 RAM 2500 models equipped with AAM 11.50 or 11.80 rear axles.
