A connecting rod for an internal combustion engine including an elongated rod portion. Also, a first annular portion is integral with a first end of the rod portion. The first annular portion has a bore therethrough for engaging an engine piston pin. Additionally, a second annular portion is integral with a second end of the rod portion. The second annular portion is opposite the first annular portion. The second annular portion is divided into symmetrical halves that form a distal member and a proximal member. Lastly, an alignment portion is integral with each side of the distal member and the proximal member. Whereby, the proximal member and distal member are coupled by placing a rod bolt into each alignment portion.
