Callies Ultra connecting rods are produced from extremely clean TimkenSteel that is formulated to our exact specifications. This proprietary steel is forged in Trenton, Michigan, and manufactured 100% in our Fostoria, Ohio facility. Pride in workmanship, and attention to detail are qualities you’ll discover during careful examination of our finished product. Each step of the manufacturing history of every Ultra connecting rod is meticulously maintained by our manufacturing team. You can be confident of the material and workmanship of these quality components.
The Ultra H-Beam configuration was recently added as part of our expanding connecting rod line. Made from the same premium grade TimkenSteel material, the Ultra H-Beam connecting rod is designed to satisfy the requirements of the most demanding racing applications.
