The I-Beam “Heavy Duty” series connecting rods for the Honda K24 are designed for high horsepower applications. Constructed from premium 4340-EN24T high tensile steel, these rods feature a specially optimized shape for enhanced performance and durability. The “straight cut” pin end improves durability, necessitating the use of aftermarket pistons. The bushings are made from AMPCO 18 material, providing excellent wear and fatigue resistance, with radial grooves acting as an oil reservoir. Each rod undergoes shot peening to relieve stress and is multi-stage heat treated to enhance rigidity. Tight tolerances in the production process ensure a perfect fit while optimizing oil clearances, with controlled bend and twist. Each rod includes 3/8 ARP 2000 cap fasteners rated at 220,000 psi, with an optional upgrade to ARP L19 material rated at 260,000 psi. The complete kit is supplied with ARP moly and full fitting instructions.
