Eagle's commitment to quality and service has resulted in customer loyalty and satisfaction. This, in turn, has fueled rapid growth over the years. Eagle added crankshafts to our lineup a few years later as well as expanding our offerings in Connecting Rods. Continuous design improvements and improvements in materials and manufacturing techniques have resulted in Eagle being the largest and most respected aftermarket connecting rod and crank manufacturer in the industry. We never stop researching ways to make our products lighter, stronger, more efficient to manufacture, and more diverse. When you stop moving forward, you get passed by the competition.

Why spend time and money reconditioning your stock rods—when you can upgrade to a set of Eagle SIR I-Beam connecting rods for less? They're forged from 5140 steel for outstanding strength and reliability, and they come in both press-fit and bushed pin models. Their lightweight design places less stress on the rest of your rotating assembly to increase engine life and better handle high-rpm use. The rods are X-rayed, sonic-tested, magnafluxed, and shot-peened to stress-relieve the metal. They come with 12-point ARP Wave-Lok rod bolts and are weight-matched to within two grams. The big end sizing is controlled by in-house CNC equipment to ensure precise machining and accurate fitment. Order the individual rod or set recommended for your year/make and engine application.
