Honda B18C I-Beam Connecting Rods

Crafted from 4340 high tensile steel, these I-Beam connecting rods are engineered for high performance, extreme durability, and enhanced rigidity. The aluminum-silicon/bronze alloy bushings feature a radial groove for an oil reservoir, ensuring optimal lubrication. The rods undergo shot peening to relieve material stress and multi-stage heat treatment to maximize strength and rigidity. Precision manufacturing ensures tight tolerances for perfect fitment and optimized oil clearances, with controlled bend and twist.
