Connecting Rods So Many Choices - Engine Builder Magazine

Sep 01, 2008 · The two basic styles of connecting rods are I-Beam and H-Beam. Some rod suppliers only make I-Beams, others only make H-Beams, and some offer both types or variants of the I-Beam design. The I-Beam design is used for most stock connecting rods because it provides a good combination of light weight and strength.
