Connecting rods are one of the hardest working parts in your engine. They are subject to compressive and tensile forces during operation. Our connecting rods are manufactured out of forged steel which provides superior strength and durability. Each connecting rod includes installed pin bushings, and new hardware. All of our connecting rods precision machined and ready to install.
