BMW Connecting Rods

BMW rods in this category fall into two groups: the standard replacement rods for the N-series four and six-cylinder engines, and the 4340 H-beam rods with ARP2000 bolts that owners order when a B48 or N20 engine is being built or rebuilt for more load. The standard side covers the N12, N13, N14 and N18 engines shared with the Mini, the N20 family in the F20 and F30 cars, and the larger six-cylinder applications in the 328i, 330i and 528i.

Number matching is fairly direct. N20B20B engines take 11247624616, with 11247624615 and 11247589540 as the related references, and that rod is listed for the 320i, 328i, 528i, X1 and X3. The Mini and the small BMW fours are covered by 11247621253, 11249894657 and 11247550568. On the six-cylinder cars 11247558590 and 11247589532 are the numbers to compare with the old rod. For performance builds, 4-TR-005 is the 4340 H-beam rod with ARP2000 bolts, offered for the B48B20 2.0T with a 148MM centre-to-centre length, while 4-TR-012 covers the Mini Cooper S R56, R53 and F56.

The rods are forged from alloy steel and precision machined, with dimensions checked batch by batch, and stock models are dispatched in roughly a week with no fixed minimum order. Send us your VIN or the number on the rod you are replacing and we will verify the correct part before you commit.
