Engine Connecting Rod 11247624616 for BMW 320i 328i 520i 528i (2012–2019)

The BMW N55 engine utilizes forged steel connecting rods measuring 144.35 mm in length, with a piston pin diameter of 22 mm—specifications typically shared with the S55 engine. In factory applications, this 3.0-liter connecting rod typically features a “cracked” big-end design; however, aftermarket upgrade solutions frequently offer H-beam or I-beam connecting rods forged from 4340 alloy, often paired with 3/8-inch ARP 2000 fasteners to further enhance strength.
