Howards Ultimate Duty Billet Steel Rods (DSM 6 Bolt with 22mm Wrist Pins)

The research phase for these connecting rods consisted of a process called Finite Element Analysis which helped us to determine the weakest points of the factory connecting rod design. Using that information we developed a prototype using state-of-the-art CNC equipment that included the finest high nickel AQ4340 billet steel material, Ampco 18 bronze wristpin bushings, Manton alignment sleeves, and massive 7/16" ARP 2000 series fasteners (torqued to 70 ft lbs using the supplied lubricant). In the final development phase the prototype was heat treated, fully stress relieved, and shot peened to ensure that no stress risers or surface imperfections remain. The end result: A 652 gram connecting rod that we feel is the strongest and most reliable steel connecting rod available on the market for this application.
