These Speedmsater I-beam connecting rods incorporate all of the best features possible for an I-beam rod, including some strength adders found in H-beam designs. Speedmaster I-beam connecting rods are profiled with clearance for long stroke applications. These connecting rods feature a one-rib cap design for added strength and bearing support, polished beams to eliminate stress risers.
