BoostLine connecting rods are designed specifically for demanding turbocharged, supercharged, and big nitrous applications. The patented, 3-pocket body forged from premium 4340 steel incorporates the best features of both the H-beam (mass/weight) and I-beam (strength) designs. This provides 60 percent more bending strength compared to common H-beam rods. Each piece is heat-treated, shot-peened, and fitted with ARP-2000 cap screws (strong, malleable, and 220,000 psi rating) before final finish machining. Keep things straight with a set of BoostLine connecting rods (also available individually). Order the connecting rods in the model recommended for your specific engine size.
