Eagle
Eagle Specialty Products has been a trusted manufacturer of high-performance forged and billet engine components for over 35 years, producing connecting rods, crankshafts, piston rings, and rotating assembly kits that engine builders rely on when stock parts are no longer adequate for the power level being chased. The brand's 4th generation H-beam connecting rods, known as the 4D design, address the most common failure points in previous-generation rods by increasing big-end rigidity through thicker webbing and an improved beam profile that resists bending under high cylinder pressure. Eagle rods are 100 percent CNC machined from 4340 chromoly steel, include ARP 2000 rod bolts as standard, and are popular for both street-strip builds and dedicated track-day engines on a range of domestic V8, LS, and sport compact platforms. Builders who want proven rotating assembly reliability without custom billet pricing consistently choose Eagle as their go-to rod supplier.Popular UpgradesEagle'...
