Alum Water Neck 1.50IN Hose GM LS1 LS2

The Alum Water Neck 1.50IN Hose GM LS1 LS2 from REDHORSE PERFORMANCE is a specialized aluminum water neck adapter designed specifically for GM LS-series engine builds. This component is essential for those upgrading their cooling systems, installing custom radiators, or transitioning between engine platforms, serving as a critical interface between the engine block and coolant hose routing.

Constructed from lightweight aluminum, this water neck features a 1.50-inch hose outlet diameter, ensuring compatibility with standard 1.5-inch coolant hoses commonly used in performance cooling systems. The aluminum material not only reduces overall engine bay weight but also provides excellent thermal conductivity for optimal coolant flow and heat dissipation. Its precision-machined design guarantees a leak-free connection when properly installed with quality hose clamps.

LS enthusiasts performing engine swaps, radiator upgrades, or custom cooling system designs will find this direct-fit water neck particularly valuable. It simplifies coolant system layout and eliminates the need for adapter stacking, which is crucial when space is limited in modified or swapped LS applications. However, it is important to verify compatibility with specific LS1 and LS2 setups to ensure optimal performance.
