GM LS 4340 Forged H-Beam Rods

The EAGLE GM LS 4340 Forged H-Beam Connecting Rods are essential components for any serious LS engine build, catering to both mild street performance and extreme competition power. These rods are designed for builders and enthusiasts who require reliability under high RPM operation and aggressive ignition timing.

Constructed from premium 4340 steel, these connecting rods offer exceptional tensile strength and fatigue resistance, making them suitable for both forced-induction and naturally aspirated applications. The H-beam design efficiently distributes loads, reducing stress concentration and extending component life in high-boost scenarios.

Ideal for LS1, LS2, LS3, and LSx variants, these rods are perfect for those looking to increase horsepower through turbocharging, supercharging, or nitrous oxide systems. Note that installation requires proper resizing and honing to specification, and high-quality fasteners must be sourced separately to ensure optimal performance.
