Good To Know
Q: How do I identify if I need .020 over rings? A: You need these if your machine shop has machined your cylinder block by .020 to remove surface scoring.
Q: What is the importance of the bore size? A: The bore size determines the diameter of the cylinder, and the ring must match this diameter to seal combustion gases.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
