Proudly made in the USA, Wagler Competition Products 6.6L Connecting Rods are forged by Trenton Forging in Trenton, Michigan with the forging made from 4340ACQ certified material. The updated I-Beam design handles greater horsepower and torque than previous versions. This has been enhanced by adding beam thickness, adding strengthening ribs, 3D profiling, and larger radiuses to reduce stress risers.

Wagler Competition Products integrated a state-of-the-art Tongue & Groove with locator design that keeps the end user in mind to align and lock cap to eliminate offset caps and maintain a true bore.
