Ultimate Duty 156mm Long I-Beam Connecting Rods for Evo 8/9

Howards Racing Components 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!

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 (Torque to 70ft 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 634 gram connecting rod that we feel is the strongest and most reliable steel connecting rod available on the market for this application.

Disclaimer

Designed for use with the earlier "6 Bolt" rod bearings for more load capacity, these connecting rods fit most readily with OEM Mitsubishi cranks. For proper fitment of the rods, chamfering of the bearings will be required when used in conjunction with an aftermarket crank. Please consult with your engine assembler.

In order to increase bearing surface area and load capacity these connecting rods utilize rod bearings from the 1990-1992.5 6 bolt 4g63 (ACL Part # 4B1146H).
