The I-Beam Connecting rods for Renault 1.8L & 2.0L are manufactured from 4340 high tensile steel, they are designed for high performance, extreme durability and extra rigidity. This “Lightweight” design combines lightweight performance with proven reliability at an extended rpm. The bushings made from AMPCO 18 material for excellent resistance to wear and fatigue and have radial groove for oil reservoir. 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 220,00 psi, optional ARP L19 material available as an upgrade. The Connecting rod kit supplied with ARP moly and full fitting instructions.
