Description

The Mag-Hytec AA14-12.0 Rear Differential Cover is constructed from high-quality cast A356-T6 aircraft aluminum in the USA, designed to keep your differential remarkably cooler than a stock cover. It features external cooling fins, an increased fluid capacity of 8 quarts, and a magnetic drain plug for superior protection and easier maintenance. An O-ring seal eliminates the need for messy gaskets, and a pre-tapped 1/8 NPT port is included for a temperature sender.
