Set of 6 138mm connecting rods to be paired with our pistons specially designed to work with the 138mm length and 21mm pin.  These rods are for a honda B18c but also fit on the M5X crankshaft.  Requires use of a B18c rod bearing.
Weight is 589 grams with bolts.  This is an extreme duty rod designed for the highest cylinder pressure applications possible with a steel rod.  If you want the strongest possible rod without going to aluminum rods, this is the rod for you.
 
"BoostLine connecting rods are designed from the ground up for high-power forced induction and nitrous applications. A patented, 3-pocket design, forged from premium 4340 steel, maximizes strength while minimizing rotating weight. This revolutionary design dramatically improves the rod's big-end stability under tensile loads and provides a 60% improvement in bending strength and 20% stress reduction in tension compared to H-beam designs. All of these benefits make BoostLine rods ideal for high-cylinder pressure engine combinations."
