The I-Beam Connecting rods for Honda K20 are manufactured from 4340 high tensile steel, they are designed for high performance, extreme durability and extra rigidity. The bushings made from Aluminum – silicon/ bronze alloy and have radial groove for oil reservoir. They are shot peened to relieve stress from the material and multi-stage heat treated to increase rigidity. The tight tolerances in the production process, ensure a perfect fitment while optimizing the oil clearances. Bend and twist is tightly controlled.
