Speed Factory Racing 138mm connecting rods, set of 6
  • Speed Factory Racing 138mm connecting rods, set of 6

    H-Beam connecting rods to pair with our M50/M52 pistons designed to use a 138mm honda rod. The longer length improves rod stroke ratio and reduces reciprocating weight due to the lighter 21mm wrist pin like a euro S50 or S54. These fit on the crankshaft with no modification as the big end is the same size as the bmw crank. As it is a honda rod you will need to use a Honda B18c connecting rod bearing. These are sutable for turbo applications up to about 900 whp, 700 ft lbs. They are also a perfect choice for NA or supercharged applications.

    Weight is 528 grams with included ARP bolts.
