Switching out the plastic bleeder screw on a Duramax with an aluminum one from ZZ Diesel is a solid choice. It's a durable material that will provide a more reliable and long-lasting solution compared to plastic.
Plastic bleeder screws are prone to wear and tear over time, and the risk of cracking can lead to issues like air leaks. Upgrading to our aluminum bleeder screw, addresses this issue by providing a more robust and durable solution.
