Note for Pistons, Rings, Rotors, Rods and engine internals
Unless otherwise specified, some brands supply brake rotors, pistons, strut mounts, rods and rings separately. In some cases, titles may indicate plural, or 'set' - eg the term “ring set” often refers to the rings for a single piston only.

4340 ROD 6.125" 2.10" LW
Eagle now offers their CRS lightweight H-beam connecting rods in their Featherweight series. The lighter 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. They come with 220,000 psi rated ARP 2000 cap screw rod bolts, instructions, and rod bolt lubrication.
