Audi / VW 1.4L TSI & TFSI Connecting rods are H-Beam shaped and manufactured from 4340 high tensile steel. These rods have “Rifle Drilled” for extra wrist pin lubrication to prolong longevity. The bushings are made from AMPCO 18 material, for excellent resistance to wear and fatigue and have radial groove acting as an oil reservoir. They also 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. They are designed for high performance and extreme durability.
Each rod includes ARP 2000 cap fasteners that are rated at 220,000 psi , optional ARP 625+ material available as an upgrade and the whole kit is supplied with ARP moly and full fitting instructions.
