  • Service: Eagle connecting rods and cranks are designed and manufactured to our specifications. Some simply purchase generic products and package in their boxes without having any control or input in production. Eagle uses only certified steel in production of their steel cranks and rods. No shortcuts are taken that might compromise the quality of the finished piece. We use multi-stage heat treating, sonic testing, magna-fluxing, and x-ray to ensure a reliable product. While Eagle may not be the least expensive
