Specs At A Glance

Good To Know

Q: Are these rings compatible with a standard bore cylinder? A: No, these are .020 over size and require a cylinder bored to 99.5mm; they will not fit a standard bore.

Q: Do the rings come pre-gapped? A: The rings are pre-gapped but should be measured and adjusted to your specific cylinder clearance during installation.

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