Carrillo "H" Beam Rods: Fatigue is the major cause of connecting rod failure. At Carrillo Industries, they use proprietary steel, manufactured and forged to our own custom specifications. After experimenting with virtually every other reasonable material, we have found this chromium / nickel / vanadium / molybdenum FORGED alloy to be the best product to meet our stringent requirements for strength and durability.Our connecting rods are fully machined to guarantee the removal of all surface imperfections in the forging. After heat treatment, each connecting rod is 100% magnaflux inspected and hardness checked, then machined to final size. Each set of rods is balanced and then shot peened to achieve the ultimate in strength and fatigue properties.
