Eagle SIR6385B SIR 5140 Forged I-Beam Connecting Rods Chevrolet 502 Big Block

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 (3/8 on small block 7/16 on big block) 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. Perfect choice for Small Block engines producing up to 500 horsepower and Big Block engines producing up to 700 horsepower.
