Toyota 4AG 16v / 20v H-Beam Connecting Rods are manufactured from 4340 high tensile steel and are designed for high performance and extreme durability. 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. Note: The big end diameter is 43.00mm
