    Description

    Eagle SIR5956FB Forged I-Beam Connecting Rods & Ross 80555 Aluminum Forged Piston Set assemblies for a small block Ford. (Set of 8)
    ALL SOLD TOGETHER!
    USED with less than 20 hours on them.
    Bought them a while back for my ford 408 stroker project but later ended up selling the whole project. Nothing wrong with them. May have a few scuffs around the edges but nothing serious. Very useable still.
    A couple Pistons have exhaust valve marks in them but nothing major. Just a little carbon on top yet they all look like NEW still. Great buy if you need to save money for that budget build!
    DOES NOT COME WITH BEARINGS AND PISTON RINGS!!! PISTONS & ROD ASSEMBLIES ONLY!!!
    Summit Racing Offers these exact parts which can all add up to around ,000. So who ever buys these will be getting a GREAT DEAL!

    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 cheaper? 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. These 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.
