Good To Know

Q: Is the gasket set included in this kit? A: Yes, the Namura Standard Bore Size C Piston & Gasket Kit includes a complete set of gaskets needed for the installation, including head and base gaskets.

Q: Can this piston be used without boring the cylinder? A: This is a standard bore piston, so it is designed for use with a stock cylinder bore that is still within service limits; if the cylinder is worn, boring may be required.
