Where are Callies connecting rods made?
Callies Ultra connecting rods are produced from extremely clean TimkenSteel product, that is formulated to our exact specifications. This proprietary steel is forged in Trenton, Michigan, and manufactured 100% in our Fostoria, Ohio facility.
Are H or I beam rods stronger?
“H-beam is a stronger design when bending stress is considered,” Davis said. “H-beam rods are more difficult to machine, so they are often more expensive. I-beam rods are easier to produce and can sometimes be lighter than H-beams. All other variables being equal, H-beam rods are the strongest design.”
Who makes CompStar crankshafts?

Longer rods can improve rod stroke ratio, reducing thrust loading on the piston. A popular misconception is that rod length affects displacement, which it does not. Only cylinder bore and crankshaft stroke alter the displacement of an engine. Longer rods typically require shorter, lighter pistons.
