Good To Know
Q: What is the purpose of the .020 over bore sizing? A: This size accounts for a cylinder that has been bored out to remove imperfections or wear and requires a larger piston ring to maintain the seal. A: Correct sizing is vital for preventing engine seizure.
Q: Is ring gap measurement mandatory? A: Yes, you must verify the ring end gap before final assembly to prevent the rings from binding as the engine heats up.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
