The H-Beam Connecting rods for Audi/VW 2.0L TFSI (Belt Driven) are crafted from 4340 high tensile steel, engineered for high performance and extreme durability. These rods feature a "straight cut" pin end for increased durability, requiring use with aftermarket pistons. The pin end is ribbed to minimize distortion under heavy inertial loads while reducing excess weight. Bushings are made from AMPCO 18 material, offering excellent resistance to wear and fatigue, and include a radial groove acting as an oil reservoir. The rods are shot peened to relieve stress and undergo multi-stage heat treatment to enhance rigidity. Tight production tolerances ensure perfect fitment and optimized oil clearances, with controlled bend and twist. Each rod includes ARP 2000 cap fasteners rated at 220,000 psi, with optional ARP L19 material at 260,000 psi available as an upgrade, and comes with ARP moly and full fitting instructions.

Additional Machining Processes

• "Straight Cut" Pin End – Suitable for aftermarket pistons.
• 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.
