    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.
