Billet Water Neck 1-1/2in Black

The Billet Water Neck 1-1/2in Black by Allstar Performance is a precision-engineered coolant outlet component designed for custom engine builds and cooling systems. It provides builders with the flexibility to optimize coolant flow direction and routing in tight engine compartments. This product is particularly useful for those fabricating custom cooling systems or upgrading from standard fittings.

Machined from solid billet aluminum and finished in satin black, this water neck features a 1-1/2-inch hose connection port that accepts standard hose barbs and adapters. The billet construction reduces the risk of coolant seepage and micro-fractures under sustained high-temperature cycling. Allstar Performance's precision tolerances ensure a leak-free seal when properly mated with quality hose clamps and compatible fittings.

This water neck is ideal for engine swaps and custom cooling systems, making it a valuable addition for enthusiasts working on hot rods or performance vehicles. Its black powder-coat finish resists corrosion and enhances the overall appearance of the engine bay. Whether you're upgrading an existing setup or building a new engine from scratch, this component offers both functionality and aesthetic appeal.
