SBC 4340 H-Beam Rod 6.000in

The MANLEY SBC 4340 H-Beam Rod 6.000in (MPN 14054-1) is a high-performance connecting rod designed specifically for small-block Chevy engines. It is ideal for engine builders and performance enthusiasts who require maximum strength and reliability in high-RPM and high-boost conditions. This rod is particularly suited for applications such as bracket racing, road course driving, and both naturally aspirated and forced-induction builds.

Constructed from 4340 chromoly steel, the SBC 4340 H-Beam Rod features an H-beam cross-section that provides superior rigidity and fatigue resistance. The 6.000-inch length is precision-forged and bushed at the small end, ensuring a consistent piston pin fit while minimizing wear. The cap end is designed to accept 7/16-inch cap screws made from 8740 bolt grade material, which is crucial for maintaining rod geometry under stress.

Engine builders appreciate the consistent dimensional accuracy and material quality of MANLEY connecting rods, which are built to withstand repeated high-stress cycles. The lightweight design of 1.45 lbs helps reduce rotating mass and reciprocating inertia, enhancing engine efficiency and response. This rod is a reliable choice for anyone looking to enhance the performance of their small-block Chevy engine.
