What does 'plain ring set' mean?

A plain ring set typically refers to the compression rings only. This set does not include the oil control rings, which are usually sold separately or as part of a more comprehensive engine rebuild kit. You'll need to ensure you have the correct oil rings for your application.

Why are these rings 0.040 inch undersize?

These rings are 0.040 inch undersize to accommodate pistons or cylinders that have been machined down to match this specific size. This is common during engine rebuilding when components are honed or bored to a new specification for optimal fit and performance.

Are these rings compatible with California vehicles?

No, these rings are not CARB approved and cannot be shipped to California. Please check local regulations regarding emissions compliance for engine parts in your area.
