Overview 

The PP Rod LS 6.125" H-Beam FI Connecting Rods are engineered for high-performance LS V8 engine builds, offering exceptional strength, balance, and durability. Forged from premium 4340 high-tensile steel, these rods are heat-treated, shot-peened, and CNC-machined to ensure precise tolerances and long-lasting performance under extreme conditions. With a center-to-center length of 6.125 inches, they are ideal for stroker or forced induction (FI) applications. The robust H-beam design enhances structural rigidity, making them well-suited for high RPM and high-horsepower use. Each rod includes full-floating bronze wrist pin bushings (compatible with .927–.928" pins), and the big-end is fitted with 7/16" ARP fasteners—available in 8740, ARP 2000, or L19 for various power levels up to 1,600 horsepower. The rods are weight-matched within a few grams, and the set undergoes thorough non-destructive testing including magnaflux and sonic inspection to ensure integrity. Designed to handle the demands of modern turbocharged, supercharged, or nitrous-fed LS builds, this set of 8 is ready for serious performance.
