Good To Know

Q: Do these rings require gap filing before installation? A: Always check ring end gap against cylinder bore specifications and file carefully if needed to avoid breakage.

Q: Can these rings be used with any piston brand? A: They are designed for Namura pistons but may work with other brands if the ring groove dimensions match; verify compatibility.
