  • Fabricated Look, Affordable Price: Get a sleek, performance-inspired appearance without the high cost of custom fabrication.

  • Durable Construction: Made from 6061 T6 billet aluminum for maximum strength and heat resistance.

  • Finish: Available in silver anodized for corrosion resistance and clean aesthetics.

  • Cast vs. Billet Aluminum: Process Differences:

    • Cast Aluminum is produced through a casting process, where molten aluminum is poured into molds, making it ideal for parts with complex shapes and varying thicknesses. This method provides good strength and corrosion resistance.
    • Billet Aluminum, on the other hand, is crafted from a solid block of aluminum through forging and machining. This process results in higher strength and durability, making it suitable for high-precision and demanding applications.

Good but not great.

The quality of the machining of the aluminum is great but the powder coat isn't the best. Not terrible but good enough for going in an offroad truck. Packaging could have been better too. Pricing was great but if you want a high quality looking valve cover, buy the raw aluminum ones and powder coat them yourself.

Aluminum Valve covers

I wasn't sure what to expect with these. I have the Holley sniper EFI Valve covers on one of my Hemi engines. I wanted to get another set of those but they're discontinued. These are definitely a good alternative, machined from one piece and they look awesome.

Thanks for the review!!!Very much looking forward to your feedback pictures.
