The BC625+ Series rods are designed for high horsepower, high boost and extreme rpm applications where nothing but the best rod will do. Features include ARP's premium Custom Age 625+ bolt rated to 280,000 p.s.i. for ultimate fastening capabilities as well as aluminum-bronze bushings to insure long, reliable service, no matter what the boost, nitrous or RPM.
