The Eagle ESP Forged 4340 steel crankshafts feature a non-twist forging and undergo a multi-stage heat treatment process as well as stress relieving, shot peening, and nitriding. The Eagle ESP Forged 4340 steel crankshafts are magnafluxed and sonic tested to insure quality. Every journal is micropolished to a 3 or better R.A. A 0.125 radius is used to increase strength, so chamfered bearings must be used. All rod throws feature lightening holes to reduce weight. Target bobweight is +/-2%.

Eagle ESP H-Beam connecting rods are forged from 4340 steel and utilize 7/16" ARP cap screw type bolts with precision alignment sleeves that locate the rod cap to help maintain big end bore size and eliminate cap walk. Packaged in a weight-matched set (+or- 1 gram). Sizing is done on the state of the art Sunnen Krossgrinding system. All Eagle ESP Connecting Rods are multi-stage heat treated, magna-fluxed, and sonic tested. The Eagle ESP series connecting rods are manufactured from a two-piece forging. The forging process forces the grain into the shape of a connecting rod, resulting in a superior fatigue life. The rod cap is forged separately so that the grain runs perpendicular to the load forces, which strengthens the rod. Also, a higher content of nickel and chrome is used, which increases the strength and fatigue life without making the rod brittle. Extensive testing has proven the Eagle two-piece forging to be superior to any one-piece forging on the market!
