Shop with Blessed Performance for the PPE Duramax Front Differential Cover for your 2011-2019 GM 6.6L LML/L5P Duramax diesel. This Front Differential Cover increases the fluid capacity by a full 3/4 of a quart. The extra fluid cools quickly because of the added surface area, in the form of external 1/4 inch cooling fins that catch and channel passing air. It is a benefit that makes this pan cool. With their ribbed design these fins exponentially increase the exterior surface area, all of which means more air hitting more areas and thus more cooling of the fluid. The cooling continues inside as 5/8 inch internal fins act as heat sinks to draw away the high fluid temperatures to the exterior fins, where it is simply blown away. One of PPEs high powered Neodymium magnet-equipped 17mm hex head sight level/fill plugs that attracts and holds harmful metal particles are included.
