Product Description

The Manley 14028-6 H-Beam Connecting Rod Set is engineered for performance-focused builds of Nissan RB25 and RB26 engine families, offering rugged durability and precision at high RPM and high horsepower levels. Its 4340 forged steel construction and H-beam design help manage the stresses of forced induction, stroker kits, high revs and aggressive tuning.

With a center-to-center length of 4.783" and big-end bore of 2.008", these rods are designed to directly replace stock rods in the RB25DET / RB26DETT applications. The components are shot-peened, stress-relieved, magnaflux inspected and weight-matched to ensure balance and longevity in demanding environments.

Ideal for engine builders and high-performance enthusiasts working on Skyline R32 / R33 / R34 platforms, the 14028-6 provides the foundation for serious power upgrades. When installing, ensure proper rod bearing clearance, fastener torque spec (e.g., ARP 8740/2000 bolts), and full rotating assembly balancing for optimal performance and reliability.
