Description

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.
