The BC I Beam rod features ARP’s venerable ARP2000 fasteners, rated to 220,000 p.s.i. This is the same rod as the BC I Beam Extreme, just installed with the more economically priced rod bolts (ARP2000). This I Beam rod is rated in excess of 200HP per cylinder.

The EXTREME edition uses Custom Age 625+ ARP rod bolts instead, and is rated at 300 HP per rod
