Millennium Technologies Information

Millennium Technologies is a family-owned manufacturing and surface engineering company, born and raised in Plymouth, Wisconsin. Founded in 1997, we remain committed to operating locally, with all core manufacturing, coating, and quality functions performed in-house. We operate under a quality-first manufacturing philosophy built on process control, repeatability, and continual improvement. Excellence is achieved through disciplined systems, competent personnel, and validated processes—not speed or cost alone. Our quality management approach emphasizes accountability, traceability, and conformance to customer, regulatory, and performance requirements. Millennium Technologies specializes in advanced Nickel Silicon Carbide (NSC) coatings and precision manufacturing. Our coating processes are engineered, monitored, and controlled to deliver superior hardness, adhesion, roundness, and wear resistance, resulting in reduced friction, improved thermal efficiency, and extended service life. We are trusted by more OEMs than any other aftermarket plating provider due to consistent results and proven field performance. Over 25+ years, we have grown into a vertically integrated manufacturing operation offering precision machining, surface engineering, cylinder and head services, crankshaft repair, big bore manufacturing, and dyno validation. This integrated approach allows for full process oversight, reduced variability, and verification prior to delivery. Revolution Performance is a Millennium Technologies Harley-Davidson big bore product line manufactured under the same controlled processes and quality standards applied across all operations. Millennium Technologies supports motorcycles, powersports, automotive, racing, watercraft, and specialty performance markets—delivering precision, consistency, and performance without compromise.
