The aFe Pro Series rear differential cover is a direct replacement for the Chrysler Corporate 9.25 (12-bolt) rear axle. It is cast from durable A356 aluminum with reinforced ribs and holds 4 quarts of gear lube at the factory fill line. Built-in external fins transfer heat to the outside air for added cooling, while a large oil level sight glass and a calibration plug set to the factory level help prevent overfilling. Magnetic drain and fill plugs capture metal debris, and the fill plug sits at the end of an extended stick for easier servicing.
