      Heavy Duty

      Rear differential cover looks nice really thick and heavy duty. I haven’t installed it yet but it looks great. Just make sure you order the gasket because it does come with it.

    • Get one for your build

      This is a very nice looking and well made cover. I was surprised that it's recommended not to use a gasket. Only RTV.

    • Good value. Just needs a few improvements.

      Beefy cast piece with bearing stabilizers. Looks good. Paint not very durable. Needs to be powder coated. Bolts were not long enough for my GM 10 bolt. Comes with metric also??? Went and got 10, 5/16-18 x 1.5" SS bolts - just right.
