Eagle ESP H-Beam connecting rods are forged from 4340 steel.

7/16" ARP capscrew 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!

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