Specs At A Glance

Good To Know

Q: Will these rings fit a cylinder that has been overbored? A: No, these are standard bore rings and are intended for stock cylinder dimensions. If the cylinder has been bored oversize, you will need rings matched to that oversize.

Q: Do I need to check ring end gap before installing? A: Yes, always verify ring end gap against your service manual specification before assembly. Proper gap prevents binding and poor sealing.

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