The Eagle Specialty Products SIR6700B connecting rods are engineered as an upgrade from original equipment rods for various V8 applications. These I-beam rods are forged from certified 5140 steel, subjected to a multi-stage heat treatment process to enhance strength, and feature a shot-peened surface finish to improve fatigue life. Designed with precision, the SIR6700B rods boast CNC machined big-ends for consistent sizing and are sold as a weight-matched set to ensure balanced rotating assembly performance. They come equipped with ARP 8740 capscrew rod bolts for proven reliability and a silicon-bronze pin bushing to accommodate full-floating piston pins. Additionally, a pin end oiling hole is incorporated to improve piston pin lubrication. Eagle Specialty Products emphasizes quality control, utilizing multi-stage heat treating, sonic testing, magna-fluxing, and x-ray inspection to ensure a reliable product. These rods are recommended for naturally-aspirated, pump gas, and road car use, representing a quality choice for the weekend racer seeking an improvement over standard components.
