Heavy Duty I-Beam Connecting Rods for Honda S2000 F20C

The I-Beam "Heavy Duty" series connecting rods are engineered for high horsepower and boost applications in the Honda S2000 F20C. Constructed from 4340 high tensile steel, these rods offer extreme durability and performance. The "straight cut" pin end enhances durability, requiring use with aftermarket pistons. Bushings made from AMPCO 18 material provide excellent resistance to wear and fatigue, featuring a radial groove for oil retention. Shot peened to relieve stress and multi-stage heat treated, these rods ensure increased rigidity. Tight production tolerances guarantee perfect fitment and optimized 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 kit comes with ARP moly and full fitting instructions.
