Description
Connecting rods—often called “rods”—link the pistons to the crankshaft, converting combustion force into rotational motion. These components endure extreme stress from constant pushing and pulling forces, making them among the hardest-working parts in any engine. There are two main types: cast and forged. Cast rods are affordable and reliable for standard use, while forged rods, made by pressing heated metal into shape, offer superior strength for high-performance engines. Some engines use billet rods, precisely machined from solid metal for maximum durability. Material, design, and manufacturing method all play key roles in performance and longevity. Whether cast, forged, or billet, connecting rods are vital to engine strength and efficiency.
