Their patented 3-pocket design was specifically engineered for demanding turbocharged, supercharged, and big nitrous applications, and provides 60 percent more bending strength compared to common H-beam rods! BoostLine connecting rods are machined from premium 4340 forged steel and feature high-quality ARP 2000 bolts standard, with even stronger ARP 625+ Custom Age bolts available in sport compact applications.
Each BoostLine rod is designed and finish machined in the USA in Mentor, Ohio, and inspected on aerospace-grade CMM (Zeiss Coordinate Measuring Machine) equipment.
