The Eagle cast crankshaft for Chevrolet 454 applications is a two‑piece rear‑seal design with a 4.250" stroke and .092" fillet radiuses to boost strength over OE while still using standard replacement bearings. Built as a practical upgrade for pump‑gas, naturally aspirated street engines, it retains common sealing and assembly features for routine engine builds.
