Our Dana 44 heavy duty cover is one of the strongest and lightest covers on the market. The old way of thinking was to make a differential cover out of the thickest material possible, we have turned that idea on its head with our Dana 44 cover. We manufacture these covers from our 1/4" thick Ultra 100 steel, so even though they are thinner than other covers on the market they are still stronger. We are so confident in the strength of this cover that we offer a full replacement lifetime warranty. All covers are fully welded and machined flat, the threaded fill bung is TIG welded in place and the fill plug uses a 9/16 allen wrench. So if you are looking to save weight and have a cover that can handle all of the abuse that you can throw at it our Dana 44 cover is for you! These will fit the old style Dana 44s and the new JK Dana 44s. Mounting hardware is included with this cover. Recommended hardware torque is 15 Ft-Lbs.
