The Eagle forged crankshaft for Chevrolet LS engines features a 3.622" stroke, forged 4140 steel construction, and an integrated 58‑tooth reluctor. It uses a non‑twist forging process with .125" fillet radii—note chamfered or narrowed bearings are required for installation—plus a nitrided surface and micropolished finish. Intended for competition use and high‑strength applications.
