Good To Know
Q: Do I need to hone the cylinder before installing this piston kit? A: Yes, honing the cylinder to the proper crosshatch pattern is recommended to ensure ring seating and maximum performance.
Q: Can this kit be used with a stock cylinder? A: Yes, the 0.020 overbore size is designed for cylinders that have been bored or honed to that dimension; verify your cylinder's current bore before ordering.
