What is the primary benefit of a steel top ring?

A steel top ring offers improved durability and better heat resistance compared to standard cast iron rings. This makes it a strong choice for engines that experience higher temperatures or pressures, such as those with forced induction or high compression ratios.

What does the '1.2,3mm' refer to in the product name?

This refers to the dimensions of the piston rings included in the set. You'll receive a 1.2mm top ring, a 2mm second ring, and a 3mm oil control ring, which are common sizes for many performance engine builds.

Can this piston ring set be shipped to California?

No, this piston ring set is not CARB approved and cannot be shipped to California due to emissions regulations.
