Low Profile Water Neck Kit -20

The Low Profile Water Neck Kit -20 from ALLSTAR PERFORMANCE is designed for engine builders and performance enthusiasts seeking a compact coolant passage solution. This specialized water neck assembly replaces the factory unit with a low-profile configuration that reduces overall height while maintaining full cooling system functionality. It is ideal for custom engine bays, tight hood clearance, or race-focused builds.

Constructed from durable cast aluminum, the low-profile design integrates seamlessly with aftermarket intake manifolds and custom headers. This assembly allows coolant to exit the cylinder head at a downward angle, which is intended to enhance circulation patterns within the cooling system. The precision-machined passages ensure optimal thermal efficiency without the bulk of standard cooling components.

This water neck kit is particularly beneficial for small-block and mid-displacement engine swaps, LS conversions, and fuel injection retrofits. It is designed for competition builds where maximizing engine bay space is crucial. Installation requires basic mechanical skills and compatibility with your existing setup.
