Frequently Asked Questions

What size oversize is this ring?

0.020" oversize — for cylinders that have been bored 0.020" larger than stock.

Will this fit my stock bore Harley?

No — this is for overbored cylinders. If your cylinders are at stock bore, order the standard-size ring instead.

Is this a complete ring set or a single ring?

This is a single piston ring. Order the quantity needed based on your engine displacement and number of cylinders.

Why three-piece oil rings?

Three-piece oil rings provide better oil control and scraping action than two-piece designs, reducing blow-by and oil consumption.
