Callies Ultra connecting rods are produced from extremely clean Timken steel 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.
Ultra I-Beams are available in our standard weight version for extreme duty racing applications of popular Big Block Chevy, Small Block Chevy, Chevy LS, Small Block Ford, Big Block Ford, and Nissan GTR, as well as liteweight versions for select SBC configurations. For superior clamping, a bolt upgrade to Custom Age 625 material is available for all Callies I-Beams.
The Ultra H-Beam configuration was recently added as part of our expanding connecting rod line. Made from the same premium grade Timken material, the Ultra H is designed to satisfy the requirements of the most demanding racing applications.
