Eagle Chevrolet 250 Cid Straight 6 Forged 4340 Steel Extreme Duty H-Beam Rods - Set of 8

Eagle offers a set of forged 4340 steel H-beam connecting rods specifically for Chevrolet 250 cubic inch Straight 6 engines. These are built for extreme duty applications, meaning they can handle significantly more stress than stock rods. If you're rebuilding the top end of your engine for serious competition or pushing the limits, these rods are designed to keep up.

The rods start as a two-piece forging made from 4340 steel, a material known for its strength and durability under high loads. After forging, they undergo a fully machined process, followed by shot-peening and polishing. Shot-peening is a critical step that introduces compressive stress into the metal's surface, which greatly increases fatigue strength and resistance to cracking. The polished finish further refines the surface and helps reduce stress risers. Each rod in the set is weight-matched to ensure consistent balance within your engine, which is crucial for smooth operation and longevity at high RPMs.

For fastener strength, Eagle includes ARP Custom Age 625+ bolts. These are top-tier bolts known for their exceptional tensile strength and reliability, even under extreme cylinder pressure and detonation. The sizing on these rods is held to exact tolerances, ensuring a precise fit during installation. This set is sold as a complete package for your Straight 6 engine, ready for your most demanding competition builds.
