ProX piston rings are made by OEM factories to exact specifications. ProX uses well-known brands like Rikken Japan, TP, and NPR to ensure high-quality performance. These piston rings are compatible with cast iron bores, nickel ceramic platings (Nikasil), boron composite, and electrofusion bores. For OEM cylinders with chrome bores, ProX supplies a different piston ring as part of the ProX piston kit. Manufactured in Japan and designed as OEM replacements, these rings offer superior performance and reliability.
