JDY Performance Tapered I-Beam Conrods — Audi 2.5 TFSI OEM Pistons

Audi 2.5TFSI EA855 (DAZA / DNWA / DNWC / DXHA)

JDY Performance tapered i-Beam connecting rods for Audi 2.5TFSI EA855 engines are engineered specifically to work with OEM pistons, making them the ideal upgrade for hot street and track builds without the need for custom pistons.

Designed to support up to ~900 HP when paired with hybrid turbochargers, these rods deliver the same strength, material quality, and reliability as JDY¡¯s proven 2.5TFSI conrods¡ªwhile featuring a precision-tapered small end to perfectly match the factory piston pin design.

Each rod is manufactured from high-strength steel, precisely machined, weight-matched, and thoroughly inspected to ensure consistency and durability under extreme cylinder pressures.

To maximize longevity and reduce wear at high RPM and load, JDY rods feature optimised oiling pathways for both the wrist pin and crank journal, ensuring stable lubrication in demanding conditions.
