Honda H22 A1 ZRP Connecting Rods

Description

Honda H22 H-Beam Connecting Rods are manufactured from 4340 high tensile steel and are designed for high performance and extreme durability. This “Lightweight” design combines lightweight performance with proven reliability at an extended rpm. The bushings are made from Aluminum – silicon/ bronze Aluminum – silicon/ bronze material and have radial groove acting as an oil reservoir. These rods have “Ribbed pin end” that minimizes pin end distortion under heavy inertial loads while saving excess weight. 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. Each rod includes ARP 2000 cap fasteners that are rated at 220,000psi, optional ARP L19 material 260.00psi available as an upgrade and the whole kit is supplied with ARP moly and full fitting instructions. Additional machining processes: Dowel sleeves for perfect fit and accurate re-assembling; Lipped Cap Relief for improved big-end integrity at extreme application; Grooves in Thrust Face for weight reduction. Technical Features: Aluminum – silicon/ bronze bushing with radial groove, Two-Piece forging, Shot Peening, Magnaflux Inspection, Double ribbed caps, Multi Stage Heat Treatment, CNC machining, FEA analysis.
