Water Neck Spacers/Risers

Water Neck Spacers/Risers are components designed to adjust the height or angle of your engine's water neck, which houses the thermostat and connects to the radiator hose. These essential parts, often referred to as water neck risers, can be crucial for proper hose alignment and clearance, especially in custom engine builds or when aftermarket components are installed. By providing the necessary elevation, a thermostat housing spacer ensures that your cooling system operates efficiently without kinking hoses or creating undue stress on connections.

These engine coolant spacers play a vital role in optimizing the fitment of your cooling system components. Whether you need to clear obstructions, adjust hose routing for a cleaner look, or accommodate different manifold designs, water neck extensions offer a precise solution. They are available in various heights and angles to meet diverse automotive needs, contributing to a reliable and properly functioning cooling system.
