        Teraflex HD cover for a Dana 30

        Extremely satisfied with this cover, easy to install and a plus on that drain plug. Dont have to worry about taking off the cover down for an oil change. Looks awesome underneath my 02 TJ.

        Nice fit, looks great! But

        I’m happy with my whole purchase of the Teraflex front and rear covers other than the drain plug in the front cover. The cover is made to help protect the front differential from hits of objects unknown. Then why is a lower drain plug sticking out of the cover at least a 1/4” so it could possibly take that blunt hit and cause really bad damage? The rear plugs are nice an flush- why not the front? Called Teraflex and got a great answer ( not) “we’ve always made then that way”. Ever hear of changes to made something better?

        Impressed with Teraflex!

        I am impressed with the quality of the Teraflex Dana 30 differential cover. It's won't have any problems with rocks or ice. They even sent drain plugs and plugs. I will be checking out their other products.

      2 Top Rated Questions

      What size bolts and threads are these ? The ones that shipped with covers are junk and snapped off in my Diff at 15 ft-lbs now my rig is down until I can reinstall.

      • The bolts are 5/16"x18 and are about 1 1/4"-1 3/8" in length.

      Does this come with a gasket?

      • No this will just be the HD Differential Cover and the included hardware needed for installation.

          I’ve always loved Jeeps from a young age, after moving to Puerto Rico at the age 9 my uncle had a Cherry Red 73 CJ5 which I fell in love with. He would use that Jeep to ride up the mountains on his farm, I knew after seeing that Jeep I would have one. The fact that a Jeep can be so versatile in ever...
