4330 Steel I-Beam Connecting Rods, 6.125" Length, H-11 Bolts

These rods are engineered to withstand the immense forces generated by engines producing up to 1,500 horsepower, operating at speeds of 8,500 RPM, and under significant boost pressures of up to 30psi. Manufactured in the USA, these connecting rods utilize high-grade 4330 steel forgings. This premium material choice ensures optimal grain flow and guarantees the removal of any surface inclusions, contributing to their exceptional strength and durability. The I-beam design provides a robust yet lightweight structure, ideal for demanding engine builds. Each rod measures 6.125 inches in length and is designed for a 2.100-inch rod journal size and a .927-inch piston pin size. These connecting rods come equipped with high-strength Crower H-11 tool steel bolts. These bolts are renowned for their durability, boasting a tensile strength of 220,000 psi. They feature 12-point heads for secure tightening and have rolled threads after the heat-treating process to further enhance their resilience and prevent fatigue failures under extreme stress.
