Constructed from high-quality cast aluminum right here in the USA, this differential cover from Mag-Hytec keeps your differential remarkably cooler than your stock cover. This dramatic increase in heat dissipation happens for three reasons: First, the cast aluminum deals with heat in a vastly better manner than the stock steel pan. Second, Mag-Hytec designed the cover with external cooling fins to get rid of heat fast. Third, this cover holds more fluid than stock. Cool, dense fluid is always a good way to keep temperatures under control. The combination of cooling fins and additional fluid make for an exceptional upgrade to protect your differential.

Mag-Hytec also made sure this cover comes with a host of other features. To keep your fluid clean, the cover comes standard with a magnetic drain plug--designed to pull harmful ferrous metal particles right out of the oil long before they have any chance of hurting your differential. Next, the cover features a pre-tapped 1/8 NPT port for those who wish to install a temperature probe--capped with a stainless steel plug when not in use. Finally, an o-ring is used to seal the cover instead of messy sealant and gaskets. This cover allows you to drive your truck hard without fear of heat damage!
