Moroso first pioneered the aluminum water pump for racing over 15 years ago. Over the years, continual improvements have resulted in providing the best cooling system components available for competition use.
Speedway's adjustable water pump is tried, tested and true. It has great flow, superior quality and standard features that are typically only available on water pumps costing twice as much. State-of-the-art aluminum casting and a precision impeller provide equal flow to both cylinder banks. If you're using a cog belt on your race car, this is the pump you want since it's adjustable. The 1/2" mount holes in this pump are larger than normal, allowing it to be moved up or down slightly to help with belt tension.

These spacers are also ideal for clearing the tamper proof bolt on most crate engines. They help in alignment when using a crank trigger ignition as well.
