According to Nick DiBlasi, Wiseco’s Automotive Product Manager, “The BoostLine connecting rods take the best attributes of an H- and I-beam rod and merges them into one. Even though the BoostLine rod is designed for heavy-duty use, we were able to keep the rod relatively light without compromising strength.”

The challenge was to increase strength while minimizing mass. Generally, H-beam rods tend to concentrate stress at the radius between the beam and the big-end of the rod. The BoostLine 3-pocket plan dramatically improves the rod’s big end stability under tensile loads. Triangles are inherently strong and you can see this influence in the pocket shapes. This strength is especially critical at high RPM, where loads increase across the entire big-end area of the rod.

All Boostline rods are individually inspected using a coordinate measuring machine (CMM) that is used to custom-match sets of rods to incredibly tight tolerances. Most rods are matched to be within 1 to 2 grams of overall mass. When you consider an LS rod weighs 700 grams, that’s an incredibly tight tolerance. To learn more about this, watch the video below.
