Overview

The Pacific Performance Engineering cast-aluminum rear differential cover is a high-strength, thermally conductive upgrade for 2023-2026 Ford Super Duty F450, F550, and F600 trucks equipped with the Dana M315 axle. It features 0.5-inch external cooling fins to lower fluid temperatures and increases total oil capacity by 0.8 quart.

Internal windage scrapers are integrated into the cover to reduce fluid churning, which helps minimize power loss and heat generation. The assembly includes 304 stainless steel drain and fill plugs equipped with high-temperature neodymium magnets to capture ferrous particles.
