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.
