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.
