What’s the difference between H-Beam and Extreme Duty?
The H-Beam rods are rated for 900 HP, come with ARP 2000 rod bolts and the part numbers end with 3D. The Extreme Duty rods are rated for 1200 HP, come with ARP 625+ bolts and the part numbers end with XD.
Eagle H-Beam (3D) 3rd Gen Design rods utilize large-scale manufacturing to keep costs low, but only use ASME-certified 4340 steel, ARP bolts and silicon-bronze bushings. Eagle H-Beam rods are the preferred choice for high horsepower, high RPM competition engines utilizing nitrous, forced induction or exotic fuels. The 3D H-Beam rods come with 3/8″ ARP 2000 bolts. These are recommended for use up to 900hp (4 cyl) and 1500hp (6 cyl) in turbocharged applications.
Eagle Extreme Duty (XD) rods feature the same time-tested 3rd generation design, but further surface polishing improves fatigue life by removing microscopic pits and inclusions where fatigue cracks begin. In addition, ARP’s premium fastener material, Custom Age 625+, is used. ARP Custom Age 625+ material boasts a typical tensile strength of 245,000 psi vs. ARP 2000’s 220,000 psi. It comes with a hefty price tag, though. The rods are not for the faint of heart. Power ratings have not been established for these rods. Honestly, we just haven’t had any fail yet. They are not indestructible, though. We feel the power capabilities to be somewhere in the 1200 hp range for 4 cylinder and 1800 hp for 6 cylinder applications.
