Eagle forged 4340 steel crankshaft with a 4.150" stroke, built for demanding eight‑cylinder builds. The non‑twist forging and .125" fillet radiuses increase strength while the nitrided surface and micropolished finish improve fatigue resistance. Note: some installations require chamfered or narrowed bearings to accommodate the fillet radiuses.
