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.

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.
HOURS: 11:00 am to 6:00 pm Monday - Friday Eastern Standard Time
