Eagle forged 4340 steel crankshafts are great for high performance applications. They feature non-twist forging, undergo a multi-stage heat-treatment process, and are stress-relieved and shot-peened. These cranks are X-rayed, magnafluxed, and sonic-tested, so you know you're getting a top-quality piece. Each crankshaft has chamfered oil holes for improved oiling, a .125 in. radius on rod and main journals for increased strength, and the journals are precision-ground and micro-polished to less than 5 R.A. A target bob weight of +/- 2 percent greatly reduces balancing time. Many options are available; order the model recommended for your year/make and engine application.

Free your engine's horsepower on the wings of Eagle H-beam connecting rods. Their 2-piece, forged, vacuum-degassed, 4340-certified steel construction provides outstanding strength, while still weighing much less than stock rods. Each rod is multi-stage heat-treated, X-rayed, sonic-tested, magnafluxed, 100 percent machined, and then shot-peened to stress-relieve the metal. The rods have precision cap alignment sleeves to positively locate each rod cap, silicon bronze bushings for floating pin models—and are available in stroker models that allow additional cam-to-rod clearance for large stroke combinations. They come standard with 190,000 psi rated ARP 8740 and 230,000 psi rated ARP 2000 rod bolts, or 265,000 psi rated ARP L-19 bolts as upgrades. Instructions and rod bolt lubrication are included. Order the model designed for your vehicle year/make and engine application.
