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!
Sold as a set of 8 Eagle ESP H-Beam connecting rods.
