Frequently Asked Questions
How do I select the correct CP piston ring set?
Match the exact bore diameter, ring diameters and thicknesses, groove configuration, material and coating, cylinder finish, intended use, and manufacturer part number.
Are piston rings ready to install without checking end gap?
Do not assume that. Measure every ring in its assigned cylinder and set end gap according to the current CP instructions for the bore, ring material, power level, fuel, boost, and intended use.
Which cylinder-wall finish should be used?
The required hone finish depends on the exact ring material and coating. Follow CP and ring-manufacturer specifications and have a qualified machine shop verify the finished bore.
Installation Instructions
Professional engine machining and assembly are required. Follow the current CP Pistons and engine-builder instructions for this exact part number. Measure every bore and component, verify all clearances and ring gaps, clean all parts and oil passages, use the specified lubricants and fastener procedures, confirm rotating-assembly and piston-to-valve clearance, and complete the required break-in and calibration.
