Forged billet 4340 steel and an "H-Be am" design, gives these rods superior strength over stock rods; includes durable ARP 2000 fasteners and a longer life thanks to the shot-peened finish. They also feature premium bronze wrist pin bushings and are held to very tight tolerances with bores finished to +/- .0001"" and weight to +/- 1 gram per end. These are stock - length rods with a floating style wrist pin.
