I-Beam Series Connecting Rods for Audi 5.2L R8 V10 / Lamborghini Gallardo/Huracan

Designed for high horsepower applications, these connecting rods are crafted from 4340 high tensile steel, offering exceptional performance and durability. The rods feature a "straight cut" pin end, necessitating the use of aftermarket pistons. The bushings are made from AMPCO 18 material, providing excellent resistance to wear and fatigue, and include a radial groove for oil reservoir functionality. Shot peened to relieve stress and multi-stage heat treated, these rods ensure increased rigidity and durability. The production process maintains tight tolerances for perfect fitment and optimized oil clearances, with controlled bend and twist.

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
