Eagle CRS6490F3D ESP 4340 Forged H-Beam Connecting Rods Ford FE
Eagle offers their ESP H-beam connecting rods in a lightweight series. Their lighter weight design provides less rotating mass for flawless high-rpm performance. Their 2-piece, forged, vacuum-degassed, 4340-certified steel construction provides superb strength at a fraction of the weight of most other rods. Each rod is multi-stage heat-treated, X-rayed, sonic-tested, magnafluxed, 100 percent machined, and shot-peened to stress-relieve the metal. The rods have a stout cap screw attachment with precision cap alignment sleeves to positively locate each rod cap.
