When you put an I-beam and H-beam connecting rod side by side, it becomes obvious how they got their names. The I-beam rod has a very robust appearance with a thick cross-section. These design differences are striking on the surface, and they each have an important purpose when it comes to how the connecting rod is used.
I-beam and H-beam connecting rods are easily identifiable because of their unique shapes. Nick Norris is part of the engineering team behind the design of connecting rods for Callies , and he explains why the material is the most important thing to look at when you select a connecting rod.
Over the years we have seen rods go through a hydraulic situation where the rod is basically turned into an S-shape. While both I-beam and H-beam connecting rods can function in the same settings, one will work much better than the other based on the application. H-beam rods are perfect for engine builds where every ounce counts. The I-beam rod lends itself better the higher compression loads, partially because of the shape up around the pin area.
The I-beam design works best in a build where a power-adder is being used because the rod offers additional strength. This is due to where the weight is added to these connecting rods among other reasons. If you're trying to make a lot of boost, an I-beam connecting rod is the best choice. When you need to lighten up the rotating assembly the H-beam connecting rod should be at the top of your list.
Some of our H-beam rods are a straight beam, while others are a tapered beam. In a high-rpm application, you want to have less weight up on the pin end. I-beam and H-beam connecting rods both vary in design features among manufacturers. You would also want to look at the width of the beam itself. The bolt placement on the rod is also important. H-beam connecting rods have some additional things you want to look at before you pull the trigger on a set, according to Norris.

This decreases the angularity of the connecting rod and thus decreases the side thrust and the resulting wear of the cylinder. Small end and big end 7. Forces Acting on the Connecting Rod 1.
