Water Neck Oulet - GM LS w/Polished Alm Finish

The Water Neck Outlet - GM LS w/Polished Aluminum Finish is a precision replacement cooling system component engineered for General Motors LS-series engines. This polished aluminum water neck serves as the critical junction between the engine block and upper radiator hose, channeling coolant flow at the optimal 75-degree angle to maximize thermal efficiency. Designed for enthusiasts, mechanics, and engine builders working with LS powerplants, this outlet combines OEM-quality construction with a premium polished finish that enhances both performance and engine bay aesthetics.

Manufactured from high-grade aluminum, this water neck outlet features a polished finish that resists oxidation while improving visual appeal in custom builds. The 1-1/2 inch ID hose connection accommodates standard GM LS cooling system tubing, ensuring reliable coolant circulation at operating temperatures. The 75-degree outlet angle is engineered to work seamlessly with factory and aftermarket radiator configurations, reducing turbulence and maintaining consistent coolant velocity. PRW Industries' engineering ensures dimensional accuracy and tight tolerances, critical for preventing leaks and maintaining system pressure integrity.

This replacement water neck is ideal for LS engine swaps, restorations, and high-performance builds where factory cooling components have aged or been damaged. It's a direct bolt-on replacement for stock LS water necks and integrates seamlessly with both street and race cooling systems. Installation requires basic mechanical knowledge and standard hand tools; simply drain the coolant, unbolt the old outlet, and secure the new polished aluminum assembly with factory fasteners. For anyone restoring an LS-powered vehicle or upgrading a cooling system, this outlet delivers OEM reliability with upgraded visual impact.
