MIA's Description

Excessive heat can degrade differential fluid, leading to wear. This PPE differential cover is cast from high-grade A356.0-T6 aluminum alloy, adding 0.6 quart of fluid capacity and featuring half-inch external cooling fins for superior heat management. Built-in windage scrapers ensure precise fluid distribution, reducing heat buildup and minimizing parasitic loss. The vertical external fins and internal scrapers form a strong cross-bracing structure that improves load distribution and enhances impact resistance. Both the fill and drain plugs are equipped with powerful, high-temperature-rated neodymium magnets to capture ferrous particles. Comes with a limited lifetime warranty.
