What Is Ultimate Duty?
Manufactured exclusively for MAPerformance by Howards Racing Components we developed these connecting rods to fulfill the needs of the hardcore enthusiast. Designed to handle 1000+ horsepower in a 4 cylinder application these truly are ultimate duty connecting rods!
Research & Development
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. 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 product that we feel is the strongest and most reliable steel connecting rod available on the market for this application.
