How We Forge Precision Connecting Rods

A five-stage production workflow refined over 55+ years of continuous improvement.

Every ROCKET connecting rod passes through a tightly controlled five-step process: CAD engineering, die forging, multi-axis CNC machining, surface treatment & heat treatment, and 100% CMM dimensional inspection. This page walks you through each stage in detail, shares the production metrics that make our output consistent batch after batch, and answers frequently asked technical questions about tolerances, materials, and lead times. Understanding our process helps you specify the right rod for your engine — and know exactly what to expect on delivery day.
