H-Beam Connecting Rods for Audi / VW 2.0L TFSI (Belt Driven)

The H-Beam Connecting Rods are crafted from 4340 high tensile steel, engineered for high performance and exceptional durability. They feature a straight cut pin end for enhanced strength, designed specifically for use with aftermarket pistons. The ribbed pin end minimizes distortion under heavy inertial loads while reducing excess weight. The bushings are constructed from AMPCO 18 material, providing excellent wear and fatigue resistance, and include a radial groove that acts as an oil reservoir. Each rod undergoes shot peening to relieve material stress and is multi-stage heat treated to enhance rigidity. The precise tolerances in the production process ensure optimal fitment and oil clearances, with controlled bend and twist characteristics. Each rod is equipped with ARP 2000 cap fasteners rated at 220,000 psi, with an optional upgrade to ARP L19 material rated at 260,000 psi. The complete kit includes ARP moly and comprehensive fitting instructions.

Additional Machining Processes

• Straight Cut Pin End - Suitable for aftermarket pistons.
