Specs At A Glance

Good To Know

Q: Do I need to hone the cylinder before installing these rings? A: Yes, always hone the cylinder to the correct crosshatch pattern to ensure proper ring seating and oil retention.

Q: Can these rings be used with overbore pistons? A: No, they are designed for standard 82mm pistons; using them with overbore pistons will result in improper gap and sealing.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
