    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.

      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.

      Great upgrade

      This is a far beefier piece then what you start with. It's solid and looks great when installed.

      Good looking

      The diff cover is a good thickness. Thicker than the OEM, that's for sure. If you like to keep your underside looking in uniform than , front and rear will help your look. I'm a jeep owner that will slightly wash the underside but, also spray paint as well. Keeps it looking clean after the dirty days?

      Easy and looks great

      The only reason that it takes a little longer to install is because you have to do a fluid change at the same time, replace the gasket, and retorque the bolts. The installation is no different than a factory cover.

      Good quality and value

      Typical Teraflex no frills high quality product. Solid and perfect finish. The D30 was powder coated inside and out. Recessed bolt design offers protection against flattened bolt heads and there is a drain plug in the front that is positioned to fully drain the housing where the OEM drain will not. Drain plug is not magnetic though so you will still want to wipe gunk from OEM magnetic plug. Only gripe is the 9mm hex fill plug means you have to make sure you throw one of those in the tool bag.
