19C RAM 2500/3500 DIFFERENTIAL COVER REAR 9.25IN BRUSHED

This heavy-duty cast aluminum rear differential cover is designed to help cool the 11.5” or 11.8" rear axle in 2019-2025 Ram 6.7L Diesel and 6.4L V8 trucks. It features specially designed internal heat sinks and external cooling fins to reduce friction, optimize lubrication, and dissipate heat, preventing degradation of differential fluid. Cast from high-grade A356.0-T6 aluminum alloy, the cover adds 0.7 quart of fluid capacity, increasing thermal stamina. Built-in windage scrapers ensure precise fluid distribution, reduce churning, lower heat buildup, and minimize parasitic loss, promoting more efficient power transfer. The vertical external fins and internal ribs form a strong cross-bracing structure for improved load distribution and impact resistance. The fill and drain plugs feature powerful, high-temperature-rated neodymium magnets to capture ferrous particles. It also includes a 1/8-inch NPT port for an optional temperature probe.
