From Forging to Finish: How Manley Performance Connecting Rods Are Made

When it comes to building a reliable high-performance BMW engine, every component matters—and the connecting rod is one of the most critical links between raw power and real-world results. That’s why at 5150 AutoSport, we trust Manley Performance connecting rods.

Recently, Manley offered a behind-the-scenes look at their manufacturing process, and it’s a perfect reminder of what sets them apart:

Each Manley rod begins life as a single-piece steel forging. This raw form is carefully crafted to handle the extreme loads found in high-RPM, high-horsepower environments. 

From there, it undergoes precision CNC machining to transform the forging into a finished connecting rod, built to exacting tolerances and proven designs.

What makes Manley stand out? From start to finish, every rod is machined under one roof by skilled technicians using advanced equipment and rigorous quality control procedures. This level of control ensures not only consistency from rod to rod, but also the kind of durability and performance engine builders can rely on.

At 5150 AutoSport, we don’t cut corners—and neither does Manley. Whether you’re assembling a street build or a competition engine, you can count on Manley rods to take the abuse and keep going.
