Frequently Asked Questions

Q: When should I use this +0.010-inch ring set?

A: These rings are specifically designed for 212cc HEMI Predator engines that have been bored out by 0.010 inches. You should use this set when your cylinder has been machined to a 70.25mm bore to ensure a proper seal and optimal compression.

Q: Do I need to gap these rings before installation?

A: Yes. Always check your end gap according to your engine builder's specifications before final assembly. Proper ring gapping is essential to prevent the rings from binding as the engine reaches operating temperature.

Q: Can I use these rings on a standard bore HEMI engine?

A: No. These rings are oversized and will not fit a standard bore cylinder. If you are running a standard bore 212cc HEMI engine, please use the standard ring set instead.

Q: How do these rings improve engine performance?

A: By providing a precise seal for your oversized bore, these rings minimize blow-by and reduce friction. This improves volumetric efficiency, allowing your engine to maintain better compression and deliver more consistent power throughout the RPM range.
