Specs At A Glance

Good To Know

Q: Should I check the end gap before installation? A: Yes, verifying the ring end gap inside the cylinder is vital to prevent seizing during heat expansion.

Q: Are these rings suitable for stock pistons? A: These rings are designed for specific over-bore pistons and must be matched to the correct piston brand and specification.

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