Eagle ESP H-Beam Forged Connecting Rods for the B18C1 B18C5 Engine. By utilizing forged 4340 steel, ARP 2000 fasteners, and state of the art machining system, these con-rods are made of the highest quality and built to be abused.
As a general rule of thumb, we tend to use Eagle Rods on anything that will be making up to 150hp per rod. So if you are planning on making over 600hp on your 4cyl, We suggest that you ask us about one of our stronger rod options.
Eagle Rod features “Two Piece Forging” and high quality H-BEAM Forged 4340 steel for superior fatigue life. Rod caps are separately forged for the grain to be perpendicular thereby strengthening the connecting rod. Eagle also uses special “mix” in their ESP 3-D lines to further strengthen & extend fatigue life without making the rods brittle.
