Ultra Rods are proudly made entirely in the USA from start to finish.
The process begins in Trenton, Michigan at Trenton Forging Company , where each forging is produced with the strength and quality serious performance demands. From there, the forgings are sent to our facility in Fostoria, Ohio, where every Ultra Rod is fully machined, finished, inspected, and prepared by our team in house.
At Callies, American manufacturing is more than a label. It is the people, precision, craftsmanship, and pride behind every part we produce.
From raw forging to finished connecting rod, Ultra Rods are built with one goal in mind: delivering uncompromising strength and performance for engine builders who expect the best.
Forged in Michigan. Manufactured in Ohio. Proven everywhere. https://www.callies.com/connecting-rods/
