Integrated Engineering Forged Connecting Rods - 144 x 20 - Rifle Drilled Audi A4 96-08/Golf R MK6 12-13

Achieve your performance goals with IE H-beam connecting rods that will make your build a success. IE Rods are designed for strength and reliability to support performance builds up to 600 horsepower and torque. Engineered to be fairly light weight for a high power to weight ratio making them the perfect choice for aggressive street builds.

All IE connecting rods are designed on and per engine application basis for factors such as cylinder pressure and rotating assembly mass. Many other brands simply change dimensions and do not engineer for the specific application at hand. FEA and computer simulation software is used to ensure the highest quality product.

The two most important dimensions of a connecting rod are the tolerances and roundness of the crankshaft journals and wristpin bushings. IE Rods are machined in-house on our top-of-the line USA made Sunnen rod hone machine that ensures proper critical roundness. After machine work is finished, every rod set undergoes a strict quality control process to verify all tolerances, weight balance, bolt threads, and surface finishes.

Rifle drilling is a machining process that adds a small hole directly through the center of the connecting rod. This galley force-feeds oil pressure from the crankshaft journal through the rod to the wrist pin bushing. Providing extra lubrication greatly extends engine life and reduces wear on the wrist pin and wrist pin bushing. Rifle drilling upgrade is highly recommended for street cars that will be driven for extended miles.
